| I would like to learn about differences between available varieties of Hoya pottsii varieties . I thought it might be a good idea to have a thread about them . It will be nice to have picture of a typical leaf and if available, flower . Growing tips, additional info such as fragrance and habits would make it even better. Is anyone interested in contributing? |
|
|||
| I will post pics of the leaves of the H. pottsii I have. It is suspected that many Hoyas we know by other names (H. aldrichii and many more) are really different forms of H. pottsii...it is a widespread species. Leap. The net will appear. |

| I have a pottsii (came as an unrooted cutting a few years ago as a NOID) but was later told it was a Pottsii... Mine grows outside most of the year and gets a few hours of sun...gets watered 2x a week in warm/hot weather and once a week in the winter...I've not noticed much fragrance to mine though...  Below was purchased as H. nicholsoniae...the leaves are a little similar to me to the Pottsii? but the leaves are not as thick as my Pottsii...   Does anyone know if Pottsii and Nicholsoniae are related...different clones?  |
|

| Nancy, that first photo is not H. pottsii...looks more like H. acuta or .....? Do you have picture of the flowers? H. nicholsoniae IS a H. pottsii. Here is a line from the Liddle Catalogue: 18 I pottsii syn.nicholsoniae 'Kuranda Qld.' very dark red leaves,flowers yellow,pink tinged white corona. $5.50 The "18" refers to his number IML 0018. H. pottsii are like all the H. lacunose out there...same species but different clones of the EXACT same plant. If you will note, the venation of the two are not alike. H. hellwigiana is also considered a H. pottsii. Like all Hoyas (even plants for that matter) the same plant grown in different environments can vary...and H. pottsii has been found in many different places in Australia (Mt. Lewis, etc.) as well as on some of the islands. WHY they get different names is the subject of a bad novel....mostly the names are not recognized as being 'legal' but they are common names. The differences in the plants can be thickness of leaves, recurved margins, color of flowers, long leaves vs. fat leaves..... Leap. The net will appear. |

Here are some H. pottsii. H. pottsii 'Nicholsinii'  H. pottsii IML 0616 Mt. Lewis  H. pottsii IML 0039  H. pottsii IML 0039 Leap. The net will appear. |

| I am still confused. If someone showed me a few leaves, I do not think I can say which pottsii it is. I have pottsii chiang mai, no blooms yet. Here is an article at Simone's website . So many variants of pottsii listed here but not much about how to tell them apart. My computer automatically translates from German to English. Not sure if everyone can read it.-http://www.simones-hoyas.de/Hoya%20nicholsoniae.html Here is picture of pottsii chiang mai I have and leaves are very thick. It is making new leaves and I have to see if they get red in stronger sun light.  |
|
|||
| Alka....yes, that is H. pottsii 'Chiang Mai'.... Maybe I am missing something...but I guess I don't understand your questions. H. pottsii is ONE SPECIES because all of the clones/variations confirm to the 'type' (the piece that was submitted when it was published). There is NOT going to be a large difference; perhaps in the amt. the leaf turns color in UV light, perhaps longer than wider...perhaps? There is not going to be a noticeable difference because they are all H. pottsii. It is like wanting to know the difference between Cocker Spaniels from England, France, the US and Poland.... Leap. The net will appear. |

| What I would like to understand is the differences between pottsii clones and also would like to see various pottsii pictures . If someone is new to Hoyas, like to collect a few pottsii , this information will help. Even if people are not able to tell much difference, hopefully they can refer to pictures (and information) here for guidance. For example, you just recognized mine was pottsii chiang mai. How do you tell it apart from nicholsoniae? You would say leaves are thicker, leaves turn red in sun, flowers are big and yellow etc etc ( I am just making up the difference since I do not know it myself, to elaborate on my question). I know it is just like lacunosas and pubicalyxes but one can still point out differences in leaves or flowers. ( When I joined this forum, I asked same questions about them too and I still find it tedious to get info because you can not find it in one place). With all the growers here, may be we can develop a nice guide. I just notice that IMLs 0037, 0038, 0018 are all listed as nicholsoniae on Simon'e website. Though he does say where each one is from but the buyer would like to know the difference in the appearance of leaves/flowers. Having all the information in a place helps a lot. This is the best I can explain . *-* Recently went to the orchid show and someone was selling a pottsii. Now, without knowing difference, I could be buying another chiang mai or a clone I already have. Seller did not have labels on the cuttings and he himself was unable to guess what cuttings he was selling. He had a laminated poster showing flowers and would say this cutting with this leaf has these flowers. I bought a cutting that may turn out to be a fitchii. You should have seen the crowd there. Lot of people do not care for the names.  |

| H. pottsii 'Chiang Mai' usually has thick leaves when grown in normal conditions...and you told us it was Chiang Mai...I was only agreeing with you. Looking at it more closely, I doubt it is H. pottsii. It seems to be tri-nerved with very prominent veins, and if you look at the other pictures I posted...the venation is very different. I should have looked more closely. I have 4 pottsii. I have put up the pictures. I suggest you Google David Liddle's 2013 Catalogue and read his descriptions of the various H. pottsii but I really don't know any more than I have already posted. While he often mentions the flower color, this is NOT a constant. Let's use the analogy of dogs: Labradors from England and Labradors from France have the same defining traits, yet they are different. OFTEN the French breeds tend to be larger, heavier boned. But they are Labradors and in a picture hard to tell apart. Often a mutt can look just like a Labrador and a Labrador can look like a mutt (mixed breed). Hoyas are no different. There are so many seedlings out there given names that are wrong. I cannot say "because the leaf is longer than...." because on the same plant I can have short fat leaves and long thinner leaves. In the past when I have tried to help, I have received emails telling me I am a pushy know-it-all and that I offend everyone...and if anyone feels that way, I apologize. I seem to be the only person going out on a limb to say anything. Perhaps there are others out there who have more to say and better information. GREAT!!!! Please come forward. Leap.

Carol, I do value whatever information you or anyone can provide. Feel free to tell all you know and if it gets a bit spicy , I can handle that.  Now. Yes I know I said it is pottsii chiang mai . By the way it is IML 0087. Came from a very reputable and kind grower who has been growing for long time. And I trust him . I think the reason you also agreed is probably because it does look like pottsii chiang mai . Here is another (chiang mai leaf ) close up-  You mentioned something about leaf being 'trinerved' . Are you saying tri nerved hoyas are NOT pottsii? Just trying to understand. Here a picture of recently bought Hoya pottsii ;)  Leaf on second picture hoya is much thinner, lighter ( less weight) and smaller but that will probably change. I do not have name on that one but I trust the grower. Now see the one I think may be fitchii. Very thin leaves with lot of reticulation-  I am not sure if fitchii looks like that. And I can not trust that seller from what I saw. So I will probably be asking you all what it looks like. Hope the cutting roots. Here is another picture in which 2 very beautiful hoyas look almost identical (nichiolsoniae and hellwigiana) . Sorry for dark picture.-  If they didn't have tags, I would be totally lost. Just trying to illustrate my point so we can have some good information. No intent to point fingers here. I am just trying to learn about these hoyas. But Carol is right that it would be nice to hear from others too. Come on everybody. Share your valuable insights here please.  |
|
|||
| Hellwigiana IS another pottsii, that's why they look alike. From the first photo of Chiang Mai, I couldn't see the entire venation...it looked somehow different. The other photos do show it. The H. fitchii looks correct. As with ANY of them, you won't be 100% sure until the flower. But I would say 999999999.9% sure. The size of the leaf is different, the recurvature is different...from pottsii. Leap. The net will appear. |

| Thanks for the pointers, Carol. So far, on the basis of this discussion and what I have, pottsii should have these characteristics- leaves are generally heart shaped, thick , flatter or re-curving like ones you showed and NOT trinerved. Right? I would love to learn what a trinerved leaf looks like. Any pictures? I hope there are more people out there , growing pottsii !  |

| http://forums.gardenweb.com/forums/load/hoya/msg110247172060... Lots of links, ideas, articles to search here, Alka. I post this, only as an FYI...not as an endorsement of anything said or implied. Leap. The net will appear. |
|
|||
| Thanks for the link Carol. I saved one link in the article. Second link mentioning pictures ,did not lead to Hoya pictures. After reading all that, I did not find much about pottsii. May be never will . I do understand nothing is definite here and there is a lot of confusion. Do you have link to C.B. article and Stemma article with this discussion ? May be that will help some.  |
|
|||
| You will find the Stemma article on the Hooked on Hoya home page. BTW, if you haven't read them, you should. CB writes a diatribe, PS The Hoyan and there are years of her articles that have good information and a lot of opinions. You can get there from Google. Leap. The net will appear. |
|
|||
| Thanks Carol. Stemma article is very good. Lot of uncertainties about pottsii a a group but at least it lists a few characteristics. Good description and photo of chiang mai there . Good description of trinerved vs triplinerved leaf in that article. Guess I just have to wait to lean how to distinguish one from another. I read a few articles from CB but I forgot the name of her journal. Thanks for letting me know. |
|

Sorry for the late reply, Thanks Carol for your comments and insights...below are a few pictures of the blooms (the one I was told was a pottsii) the first picture I posted above...the leaves were not as red when I first received it...once I moved it where it received direct sun of course it got more color...   |
|
|||
| Nancy...if you look at the pottsii leaves in the photos I posted, you'll see that they have palmate venation (more than one single main vein) while yours has pinnate venation (one center vein down the middle of the leaf).... Venation in leaves is one of the major 'clues' when looking for identity... From your flowers, I would say yours is H. acuta or H. parasitica...lovely coloration in the leaves!!!!! Lovely plant. Leap. The net will appear. |

We found H.nicholsoniae at the top of the Funicular , above Cairns in about 2004. Here is a picture of the leaf. Up until today I didn't know what H.pottsii looked like. I know now. Read the original description from China too, (actually it was found in Macau) and how it grew from a leaf etc. Very interesting. Our leaf has 5 distinct palmate veins. Have no idea what the flowers look like, but this is the leaf. Does it look different to anyone. ?? Dorothy. |
|
|||
| Looks like H. pottsii to me, Dorothy... So many Hoyas with separately published names look like H. pottsii to me: aldrichii, hellwigiana, cominsii...I think when DNA is done there's going to be a HUGE lump of them. Leap. The net will appear. |
