superiores, cire. 15, lanceolatae acutae totae niveae vel summo apice 

 punctulis raris vix distinctis purpureis notatae. 



Bracteolae tubum coroUae superantes Flores inter minores bractea toti 

 inclusi. Corollae tubus latus. Faux cupularis, ostio lato. Staminodia magna 

 apice rotundata subflabellata. Labellum late unguiculatum, lamina latiore 

 quam longa, lobo mediano brevissimo bilobo, baud prominente, a lateralibus 

 semi-orbicularibus non nisi plica separato. Filamentum circ. aequilongum 

 ac latum. Anthera magna calcaribus validis thecis subaequilongis basi 

 curvatis ceterum subrectis acutis, lingula connectivi brevissima. 



Tuber and rhizomes as in C. purputascens. As there the orange-yellow 

 colour of the rhizomes (176) is mixed with a brown tinge and at the top 

 the colour of the section passes into a nearly pure yellow. 



The largest pendulous tubers, on 160 mm. long fibres are ovate, 

 with a blunt top, 50X 25. The endodermis is gold-yellow (236), the rest 

 very light-ash-coloured. ■ • 



The leaves of a young vigorous plant with 5 leaves are elliptical with 

 an obtuse, nearly rounded base and short-stalked, (petioles 35—60, sheaths 

 150—260). The broad edges of the sheath with the ligula-lobes project 

 laterally on each side to 5 mm. of the base of the petiole. At the inner 

 side the latter converge to form a "V". 



As well the sheath-edge as the ligula are very finely or hardly puberulous; 

 the latter is very finely ciliated. The leaves are long 300 X 145, 390X1^0, 

 260X120, 340X160. P = 2,2. 



Of an old flowering plant with 7 leaves, where the spike appeared 

 laterally between the sheaths, the petioles are long 100 — 320. The oldest 

 leaf 400X180, the youngest 600X 140. P. is on average 3,1, In this 

 plant the ligula is less protruded laterally and some of the projecting tops 

 are coarsely ciliated, the base of the leaf is more acute. 



The colour of the leaf is dark-green (304), much darker than in related 

 species, the nerve is colourless, without any brown, even in the first-formed 

 leaves; the surface is hairy when young, as it is in the preceding species, 

 but less copiously and the hairs are shorter. 



The central spike has two sterile bracts and no peduncular-leaf. The 

 inflorescence is often 170 X 80 — 100. It is very finely hairy like the peduncle 

 which is about as long. 



The coma-leaves (about 9) are as in C. purpurascens much longer 

 and more acute than the floral-bracts, 60 — 75 mm. long, they end in a mucro. 



The 6 lower bracts are somewhat longer than broad; the average 

 floral bracts more narrowly ovate than in C. purp/zrascens; in dried material 

 this difference not to be observed. The outer sterile leaf of a rather 

 large spike with 40 bracts was 60X45; the average floral-bracts (40 - 45) X 30, 

 having 17—20 mm. wide pouches.
