I'm very interested in Chinese deciduous Phalaenopsis (subgenus Aphyllae) and Parishianae, but it's been a bit tough to figure out how to grow them. Here is a previous ST thread where I asked for some help. I've had this P. wilsonii for about 3 years (and it was already mature plant). First winter, I kept it too warm, above 65F (and maybe too much water). Second winter, I went to the opposite; kept it at 7C (45F) for 2 months with watering once every 5-7 days, and short day light (9-10hours). I had a high hope, but it didn't. This winter, I didn't pay much attention; I kept it at 18C (65F) max 10-13C (50-53F) min and watered every day with 12hour light. Finally a success! I know that it is not a super difficult species, but I'm still pretty excited about this. But P. malipoensis in the previous thread hasn't flowered yet, it makes flower shoot(s) every year, but it is at a weird time of the year, and the flower buds don't appear. Phalaenopsis wilsonii on Flickr Notice the short, nipple-like spur, bottom side of the lip, opposite from the side-lobes of the lip, just below "hinge" of the lip. It is a bit difficult to see in the next photo because the spur in the shadow. It is right side of the yellowish area of the lip. Taxonomy of subgenus Aphyllae is pretty confusing (more details below). This short spur is supposed to be one of the distinguishing character of this species from P. taenialis (=P. braceana) according to the Stig Dalstrom's articles: Dalstrom, S. Phalaenopsis taenialis. Orchids. August 2010: p. 468-471 Dalstrom, S. and P. Ormerod, Green Phalaenopsis Orchids. December 2010: p. 706-709 Phalaenopsis wilsonii side view on Flickr Phalaenopsis wilsonii lip from the bottom on Flickr Phalaenopsis wilsonii lip on Flickr Phalaenopsis wilsonii plant on Flickr Flower color changes to greenish/broze color after the flowers were pollinated. Phalaenopsis wilsonii after pollination on Flickr According to Dalstrom, the treatment of this group by Christenson's book is not quite right. So there should be 5 species in subgenus Aphyllae. Here is my understanding from Dalstrom's articles. --- pinkish flower * P. taenialis (=P. braceana) - pink, but stress can cause orange-yellowish flower - long spur, size similar to lateral lobe - warty root. - P. braceana originally from Bhutan- But Cribb found it in SW Yunnan * P. wilsonii (=P. chunxiongensis, nipple larger?) - pink, rose, mauve flower - short nipple like spur - verrucose (warty) root -- green/brown flower * P. honghensis - copper brown flower (but green or deep pink possible?) - well defined spur - Based on Liu's cultivated plants from Yunnan * P. strobartiana (=P. hainanensis) - olive green to bronze flower - short nipple like spur - flat roots, mildly verrucose -- flowers are distinct from the rest * P. natmataungensis - dark brownish stripes and marking on the sepals and petals, not confusing. - From N. Myanmar, in 2003, described in 2010.
