Near Tainia cordifolia HOOK, f . ; but differs by the much broader sepals, 

 ungriiculate lips, and much narrower lanceolate leaves. 



It is with some hesitation that I have referred this plant to Tainia. It 

 bears some resemblance to Tainia and Acanthepldppium in its terrestrial 

 habit, large membraneous plicate petiolate leaves, few-large-flowered short 

 lateral racemes, and in having lateral sepals aduatiug to the foot of 

 the column, erect petals, footed column and 8 poUinia. Besides, it 

 resembles the former more affirmatively by the long slender column with 

 wings towards the apex and solitary leaves ; while its affinity with the latter 

 is more emphasized by the short lateral sheathed raceme, lateral sepals 

 adnating to the long foot of the column to form a large pouch-like spurr- 

 ed mentum, mobile small stipitate lips with broad incurved lateral lobes 

 and a small triangular terminal lobe, and long footed column. But it differs 

 from Tainia on one hand by the short few flowered sheathed raceme, lateral 

 sepals adnatiug to the long foot of the column to form a large pouch-like 

 spurred mentum, mobile small stalked lip with broad incurved lateral lobes 

 and a small triangular terminal lobe, and by long footed column ; while on 

 the other it is distinguishable from Acantliepkippium by the long slender 

 column winged towards the apex, solitary leaves, not fleshy flowers, and 

 free sepals. Upon considering all the characters above mentioned, I am very 

 much inclined to regard the plant as representing a new genus, Tainiopsis, 

 just intermediate between the two named genera. What is rejected from one 

 genus is accepted by the other, and vice versa. The two (Tainia and 

 Acanthepkippium) may be united to one and the same genus, when the characters 

 which separate each other are connected by the one represented by this new 

 orchid ; or the three may be regarded as distinct. In my opinion, however, 

 the new genus Tainiopsis should be regarded as a valid one, so long as 

 the two (Tainia and Acanthephippium) should stand as distinct ones.
