Thunia marshalliana - Orchid Board

Amazed that this orchid doesn't have it's thread yet.

Thunia alba (syn Thunia marshalliana as I just found out)

Easy to grow if you know what to do. Don't water until the new growth is 3-5cm / 1-2 inch. Then water regulary untill the leaves fall down then no water untill the new shoot arrives. Flowers every year with beautifull white flowers with a nice scent. Only downside is that in the warm summer the flowers last only a week.

Some people say it's a bit susceptible to mites but I've been growing mine in the living room for 3 years without any problems.

Very nice. I love the contrasting bronzy brown markings on the ruffled lip.

I didn't know Thunias are members of the Coelogyne alliance. You learn something new every day, I suppose.

Just found out that the name is a synonym according to Kew it should be Thunia alba.

Also the family doesn't seem to be clear after some extra checks I've found Coelogyninae and Thuniinae as subtribe both have Arethuseae as tribe both on Wikipedia even (different languages). So I assume it's splitters versus lumpers again.

It is lovely! That lip color is wonderful.

This is one of my favourites, and it's nice to hear that the flowers last longer than a DAY which is typical for most of these 'bamboo' orchids, at least most of those in the genera arundina and sobralia. How large does it get? I really dig the colour combo.

In regards to the taxonomy, I don't believe the Thunia have anything to do with the coelogyne. Not sure where on wikipedia you found that info - couldn't seem to find it myself but if you can link it here, that'd be great.

The earliest shared classification stage is the epidendroideae subfamily (which basically includes almost all orchids except the ones with pouches..and vanilla), within which are the tribes Arethuseae and Coelogyneae. The other bamboo orchids (sobralia, arunidna, thunia) are under Arethuseae, and the coelogyne relatives (coelogyne, blettia, pleione) are under Coelogyneae. Hope that makes sense

Wikimedia = Familia: Orchidaceae • Subfamilia: Epidendroideae • Tribus: Arethuseae • Subtribus: Coelogyninae • Genus: Thunia Thunia - Wikimedia Commons (same as Dutch Wikipedia)

Wikipedia (English) = Family: Orchidaceae Subfamily: Epidendroideae Tribe: Arethuseae Subtribe: Thuniinae
Genus: Thunia Thunia - Wikipedia, the free encyclopedia

Other linky = Coelogyninae

What can I say Taxonomy......

The plant is about 50-70cm or 20-30 inch. Mine is 50 cm but I've seen taller. The canes get to about 3 cm / 1 inch in diameter.
