difference between H. brevialata and H. incurvula

I posted this on another thread but thought I would post it here too.

These are pictures that show the difference between brevialata and incurvula. It was posted on DG a few years ago by Carol Hawaii. I don't know how to make a link to the post.

    You make some excellent points about the differences among different specimens collected and even without that it's a bit bold to draw too many conclusions from comparing two individual leaves. I'm sure we've all experienced how much variety can be produced in leaves grown in varying conditions. Or as you point out, simply due to the plant's disposition to throw dissimilar leaves.

    It is so frustrating that digital copies of every Hoya publication aren't readily accessible. I know what to ask Santa for now.

    This is an interesting topic...the difference between H. brevialata and H. incurvula are as stark as night and day. H. brevialata may have differences in the shape and size of its leaves, but the leaves on H. incurvula are all very similar. My H. incurvula has zero roundish leaves, the leaves are longer than they are wide. My H. incurvula was a gift from Chris Burton. I think the problem with this discrepancy started with a nursery (maybe two or three of them) that sold H. brevialata as incurvula or incurvula Sulawesi (which was the name on the one I purchased from Gardino's...now almost everyone on Ebay is selling brevialata as incurvula Sulawesi. I firmly believe that they are selling the plants with the name that they purchased the mother plant as...not an attempt to mislead anyone. There's only one Ebay seller that's selling brevialata as brevialata. I contacted her and thanked her for correctly ID-ing the plant. Chris Burton has an excellent article on the differences between these two hoyas...the differences are unmistakeable!! (see the link provided by Mike). If your plant has mostly roundish leaves, with an occasional oblong leaf, you have brevialata! My H. incurvula has never produced a "roundish" leaf...they are all oblong...and look absolutely NOTHING like brevialata...even the leaf colour is very different, as are the growing requirements. Brevialata has "cupped" shaped leaves....incurvula never has cupped shaped leaves...the leaves more closely resemble a miniature H. meliflua. Hope this helps!! Fondly, Patrick

    Wonderful post, Patrick. Your well-articulated description along with the picture in CB's article make the distinguishing features very obvious. Thanks! This is a breakthrough for me, even though I've poured attentively through numerous threads and articles on the topic. Now I can collect these with confidence (something I've avoided till now). ^_~ Which is lucky b/c I can't get enough of those fuzzy little sphere blooms.

    Love the "miniature H. meliflua" remark, which is just the sort of thought that pops out of my head when I am trying to describe one of my plants.

    You mention the growth requirements being different. How so?

    Patrick... thank you.. I was able to understand one of these posts.... finally... b/c my first thought regarding the pic that ?? I don't remember now who posted it regarding ID of her plant (Denise???), looked like my newly purchased brevi... now I understand the difference, but have to admit to a bit of "newbie pride"... I wasn't too far off the mark... if the experts are discussing the subtle (or not) differences. Your post was perfect for me!... I definitely have a Brevi... and will hopefully upon the success of getting the stem of the nummalaroides to root, have that one as well. thanks Eileen

    G.G., H. brevialata hates being wet...water lightly and allow to dry out before watering again. If watered too much or too often, it quickly dies. H. incurvula is tolerant of more moisture and more frequent watering. H. incurvula is very difficult to find. I was truly blessed with the gift from Chris. I could not locate this plant anywhere...other than as H. brevialata!

    Eileen...I'm so glad I was able to help you. Best wishes on rooting your H. nummularoides...not a difficult one to root. Fondly, Patrick

    I totally agree that's an awesome gift! I'm glad we have at least a couple of these plants amongst us so that the rest of us can get ourselves turned around straight. ^_^

    I'll have to keep my eyes open for this elusive prey.

    Mike, where is yours from?

    GG both of my plants have come from Paul Shirley but they were not identified by him.

    The first plant is Hoya sp Sulawesi GPS 8810. This plant has very consistent leaves as per Hoya incurvula. I am still waiting for flowers on my plant but there are photos on Paul Shirley's site.

    The second plant is Hoya sp Sumatra GPS 1775 and it shows both classic Hoya incurvula leaves as well as some that are larger and more rounded but not to the degree that Hoya brevialata shows. This may also be the plant that Dale Kloppenburg named Hoya andalensis but if it is it has much smaller flowers.

    Several of the Thai growers have these plants available but not necessarily under the proper name. I am keeping the names that my plants came with but I do expect that one or both are Hoya incurvula. Also when you see Hoya andalensis for sale and you are lucky enough to see the leaves it often turns out to be Hoya brevialata as well.

    Here are some photos of the leaves of these two plants. If you run your cursor over the photos the names will appear.
