This Chinese flower is probably the rarest Phal I own and I am so happy it finally bloomed. It is a miniature with few leaves, long root system and no noticeable scent.
The section Aphyllae can be difficult to tell apart, one of the ways to do so is to review the rear of the lip. Stobartiana does not have a spur or nipple as Fig2 and Fig 3 show. Others in this section do, for reference I add Fig 4 that shows a hainanensis with a spur.
Fig2 stobartiana with NO nipple/spur
Fig3 stobartiana with NO nipple/spur
Fig 4 hainanensis with nipple/spur
