patent acutes tips. The peduncle is dilated at its top to form a flat torus 

 which can produce 10 or perhaps more flowers, expanding successively 

 and persisting each 24 hours. It is involucrated by two large bracts the 

 inferior of which envelopes with its wide base 3/4 part of the circumfe- 

 rence, and sometimes the whole of it and is 65 mm. long. The opposite 

 innermost bract is lanceolate (50 mm. long) and closely appressed agâinst 

 it. So they form together an involucrum much resembling that of A'. /«vo/u- 

 crata (Stahlianthus Gaonepain) but not connate. The fertile bracts which 

 follow have the same shape but are much smaller and diminish towards 

 the centrum in size and consistence, the outermost ones are pointed, 

 reticulate, and coloured, the innermost thin and hyaline, they do not alternate 

 but are inserted spirally, of inaequal size, the larger outermost forming 

 an inner involucre to the entire head. The outermost are 20 or 25 mm. 

 long, the innermost 15—10 mm. Each bract bears one flower and an 

 opposite small bracteole which is oblong, thin, hyaline binerved and 

 bidentate. the teeth being separated by an obtuse sinus. It makes quite the 

 impression of being composed of two connate bracteoles; length about 

 15 mm., teeth 2 mm. 



The bracts are much shorter than the corolla tube and have no part 

 in protecting the bud; this is exclusively covered by the tubular calyx 

 and by the convolute and long acuminate petals which perforate the calyx. 



The flowers vary in length from 60 to 120 mm., the calyx from 30 

 to 60 mm. The latter is often pink-coloured. The lobes of the labellum 

 are always very asymetrical, the inner edge being much more convex than 

 the outer, they vary in length and width, measuring mostly half the length of 

 the labellum, sometimes however a litle more. The staminodes are in the 

 genuine form always oblong rounded at boths ends or acute at the top 

 and with a small mucro, but in numerous forms as f.e. in both forms 

 designed by Wight Ic. 1029 they are obovate-lanceolate. The appendage 

 of the connective, bifid to the middle in the genuine form, is often 

 not bifid tnit 3 dentate with a shorter middle tooth or irregularly 4 

 dentate.
