Hoya polystachya, tjadsmalangensis, macrophylla (non variegated or albomarginata...just the plain jane macro), or clandestina. Until it blooms, it may be next to impossible to know for sure, as all thses have similar leaves. Definitely not merrillii!

You could probably rule out tjadsmalangensis and macrophylla, if the leaves don't redden in high light...still looking up more info.

Nevermind, lol. You can rule out tjadsmalangensis, but macrophylla is a stable green UNLESS it is variegated or albomarginata. New leaves may be reddish.

Thank you so far, Aurora ! The closest foliage match I ever could make using the images on Google was the Macrophylla with the yellow edge, but without the yellow. That one has pretty much the exact same veinage as mine.

Thanks, Marco

This is my new Hoya Merrillii. The leaves are dark glossy green but no where near the length of yours. I purchased it from Gardinos that grows it outside in FL.

Could it be Hoya rigida? It looks similar to mine...

Pug, you have an EXCELLENT point. It does look like a couple of my rigidas, as well!

I'm not sure, Pug. This group they're in all look so similar. The vein pattern is exactly like Aurora's two pics. All I know is that it won't blush in direct sunlight. It tried to make 3 peduncles on the end of 2 barren vines early this spring and they were a pinkish/red color. Then it got cold for 4 nights and they turned solid and died.

Marco

Its definitely similar so its a pretty good guess,lol...

I am easy to please, Pug, lol. The leaves are rigid, that's for sure ! The Google images look similar but some had leaves that are wider in the middle (like Monicas Merrillii) or red blush. Mine are just shaped like daggers. Watch the silly thing make a bloom that is nothing like we are thinking, wouldn't that be a hoot ! My thanks for everyone of you and your effort to help me ID this one. I appreciate it greatly !

Marco

Monica, that Merrillii of yours from Gardino's is beautiful !

Marco

It could be a reverted macrophylla albomarginata...mine reverts occasionally. Waiting for this one to flower is going to be a challenge for my patience, lol!

And I thought the few Pubicaylx's that I have are confusing. I will bring it back into the front, nearer the sun and see if it will bloom. Thank you aurora ! I appreciate your sleuthing ! I will try to assist you by getting this mystery to flower.

Marco

Thanks Marco. I was very pleased with my last order from Gardinos.

Yes Monica, they sure are great people. You have gotten some really beautiful plants from them. Did your Merrillii come with any reddish leaves or was it all green ? I got an Iligiorum from them last November and it's growing wild.

Marco

Gardino is great, I've gotten several of my Hoyas from them...

Merrilli is one of theml purchased 2011 :o)

Nice one Pug. It was a picture like this that had me question my plant's ID. I saw the beautiful red tips and went , WOW ! mine don't do that ! That's when I started digging into my plants true ID. Has it bloomed for you ?

Marco

Hi Marco, my plant is a beautiful, dark and glossy green one. I love it! Now if it turns a reddish color like Pug's I may have to carry it around with me because I wouldn't be able to stop looking at. lol

Maybe they need to mature more before they take on the red tones? Not sure. I currently have it in a north/east window.

I'll throw out yet another suggestion... looks close to aldrichii as well...

Denise in Omaha

No Denise, they all are the same thickness, thinner than the leaves on the Nicholsoniae I got from you. They are stiff as a board once the are fully mature.

Marco

I'm still inclined to say polystachya...but, until it blooms, it will remain a mystery!

aurora, I am leaning in that direction as well. The leaf vein pattern and texture are identical. I have got to get this sucker to bloom ! Thanks for all the work trying to solve this for me. I appreciate everyone's input.
