Lip sessile on the base of the column and parallel to it, equal in length 

 to the sepals, fleshy, ovate-oblong, concave, blunt, without lobes or teeth ; 

 spur minute. Column half as long as the sepals and lip, wingless. 

 Anther terminal, two-celled, convex, rather broad. Pollinia 4, free, 

 waxy, and without appendages, unequal in size, obovoid. 



As regards habit and external appearance this genus very closely 

 resembles Tipularia^ to which it is indeed allied. It differs however 

 from that genus notably in its pollinia having no appendages. The 

 column in this is shorter than in Tipidaria, and the lip has no lobes of 

 any kind and only a minute straight pouch, scarcely amounting to a 

 spur; whereas in Tipularia the spur is much longer than the ovary and 

 much curved ; the lip is also different in the two. The pollinia of this 

 are in fact like those of the aphyllous genus Gorallorhiza in form. In both 

 genera the masses are unequal : the anterior pair being the larger. The 

 column in this is also like that of Gorallorhiza^ except in the absence of 

 any trace of wings : the lip of this is however sessile on the column, 

 whereas in Gorallorhiza the lip is clawed at the base. In Tipularia 

 the inflorescence is a scape rising from the base of the leaf-bearing 

 pseudo-bulb, whereas in Didiceia the inflorescence proceeds from the 

 apex of the pseudo-bulb. 



The genus is dedicated to its original Collector Dr. D. D. Cunning- 

 ham, F. R. S., C. I. E., and the consonants in the name proposed for it, 

 are derived from his initials. 



DiDiCiEA CuNNiNGHAMi, King and Prain. Terrestrial, with a small 

 pseudo-bulb bearing from its side a single leaf and from its summit a 

 scape 5 to 9 in. long about one-third of which is spike. Leaf broadly 

 ovate, 3-nerved, sub-acute the edges undulate, slightly narrowed at the 

 base to the narrow channelled petiole ; length 1*5 in., breadth '85 in. ; 

 petiole '5 in., slightly expanded at the base. Scape with two or three 

 distinct blunt convolute sheaths ; spike 1 to 1* 5 in. long, laxly-floweied, 

 elongating in fruit. Flov^ers '1 in. long : floral bract minute, triangular, 

 shorter than the pedicel of the ovary. Sepals and petals sub-equal, 

 narrowly oblong, blunt ; spur of the lip very short, pointed. 



Sikkim: in the Lachen Valley; the exact elevation unknown, 

 but probably about 12,000 feet ; in flower in July. Cunningham (with- 

 out note of locality or elevation) ; Pantling No. 896. 



This was originally collected by Dr. D. D. Cunningham, F.R.S., 

 C.I.E., in the Sikkim Himalaya in 1889. It has more recently been 

 brought in by the collectors of the Botanic Garden, Calcutta.
