    This plant originated with Fred Hillerman years ago & I was fortunate to secure a division some time back. The original plant is labeled Jumellea pachyra but I'm not absolutely convinced of the ID. The flowers open yellow & turn white later. The growth habit is a bit rangy with lots of basal offsets. I grow it bright, hot & humid - it's hanging on the warm end of the GH high in the peak near the exhaust fans. Any thoughts on the ID would be appreciated.

    Not sure on the ID, but that's another I'd love to find.

    Beauty, J.pachyra should have very short spur 12mm so it is NOT for sure, but maybe it is Jumellea rigida because of this visible fine central keel on the lip? And plant habit looks rather similar as well:

    http://www.flickriver.com/photos/tags/Jumellea+rigida/interesting/

    rigida:
    leaves 8 to 10 length: 8-12/1.2-1.6 cm
    pedicel with ovary: 4.5-6.5 cm
    sepals: 2 cm
    petals: 1.7 cm
    lip: 2 x 0.7 cm
    spur- S shaped 9-10cm

    "wonderful scent at night"

    I think you may be right. The only thing that doesn't fit precisely is the dorsal sepal - mine seems to be a bit more reflexed than the photos in the link. Might be due to differences in flower age. Funny ... I'd keyed on rigida a couple of years ago as well but then I ran into "rigida" in a California nursery ... that was completely different ... and so ruled mine out as something else.

    Thank you for the input. Greatly appreciated.

    Beautiful plant!

    As for the ID -- I may have to sit down with the angraecoid bible and see what I can find. :) And it is entirely possible that the plant at the nursery you saw was mislabeled. That has certainly been known to happen a time or two. :)

    In my opinion it is J.rigida!!
    Great blooming!!

    DO you give it cold during winter, with less water??

    Thanks Giles. Rigida seems to be the consensus.

    The root tips on this plant definitely cover with velamen in the winter so I pull back on the water quite a bit - it probably sees water one to twice a week only. It's in a large hanging basket in the higher part of the GH. Nothing really gets cold in there - even in the winter - absolute lowest is 55F. On dreary days it never really gets much warmer than that - maybe 59 or 60F max.

    I have a couple of rigida and the *only* time I saw blooms was when I put the plant outside for a season. As I recall they need pretty much the strongest light possible and aren't frequent bloomers, so keep up the good work!

    I decided not to put any Angs outside this year and I noticed that quite a few that I would normally have put out on the back patio seem to have suffered. But the flip side is that if I *had* put them out, they would have experienced 61 days over 100 F. and almost zero natural waterings and regular humidity readings in the teens. Freakin' La Nina blows. :mad:

    Hmmm ....

    I think you should send that to California for closer inspection.

    Awesome! This is a cool Jumellea, good on ya for growing it all these years.

    I highly recommend Phillip Cribb's Field Guide to the Orchids of Madagascar for its massive taxonomic key and gorgeous photos. Your ID quandary for this plant makes me wish I had a personal copy to refer to help you. Using that key is more efficient that reading and analysing every description in Stewart's Angraecoid Orchids.

    Jumellea rigida is an intermediate/cool grower because it comes from 1500 to 2400 metres. If indeed your plant is J. rigida, your night temperatures being on the cool end or warm (or warm end of intermediate) would no doubt be responsible for making your plant the happy creature it is.

    I've been waiting for the price to drop some more. When Stewart's book was published I paid top dollar 'cause I couldn't live without it ... and then watched the price fall like a stone. I bought a second, brand-new copy the other day for $7.95.
