length, and 6-8 lines wide. Tlie slender puberulous peduncle only 

 reaches 2;^ in. ; the longer of the two is about 12-llovvered ; the 

 membranous setaceous bracts are 8-2 lines long ; the stalk, with 

 ovary, slightly longer. The sepals are 2^ lines long, the very acute 

 dorsal one 1^ lines broad, the two lateral 1^ lines at the base ; the 

 petals are 2 lines by ^ line. The lip is 2^ lines long, including 

 the apiculus, by 2-|- broad ; the column ^ line long by f line broad. 

 The anther-cap is small and rounded ; the pollmia roundish, and 

 attached by a short band to the gland. 



Polystachya nigrescens, sp. nov. Planta sicca nigrescens, 

 caule tenui elongalo a foliorum vaginis obtecta, foliis ligulatis 

 vel oblongo-ligulatis apice obtuso mtegris ; racemo terminali, 

 bracteis triaugulari-subulatis ; sepalo dorsali a basi truncata ovato 

 apice abrupte acuto marginibus incurvis, lateralibus intequaliter 

 triangulis valde apiculatis antice in galeam brevem productis ; 

 petalis e basi angusta spathulatis apiculatis, labello breviter unguicu- 

 lato oblato antice triangalari et piloso, disco cum callo linguiformi 

 instructo ; columna brevi, ovario 8-alato. 



Hab. Euwenzori. Among tree-ferns, Wimi, 7-80U0 ft., June 

 (rains), No. 7897. In heather, Butagu, 9-10,000 ft., July (rains), 

 No. 7958. 



Erect plants 9-12 in. high, turning black on drying. Leaf- 

 blades 3-4 in. long, ■§— |- in. broad. The peduncle bears an elongated 

 acuminate bract with an amplexicaul base below the short terminal 

 raceme, which is 2^ in, or less in length. The bracts (J in. long) 

 exceed the short pedicels, which, as all the flowers present have 

 been fertilized, is easily distinguished from the ovary. The dorsal 

 sepal is 3 lines long by 1^ broad, the lateral 4 by 3^ lines ; the 

 petals are 2f lines by f line in the broad upper part. The lip is 

 4 lines long, including the claw (1 line), and 3 lines at its broadest ; 

 it is drawn out into a blunt triangular tip, which is pilose on the 

 upper surface, the hairs being sparsely continued back to the 

 tongue-like callus. The short column is f line long. Fruit 

 narrowly clavately oblong, nodding, 1 in. long. 



Is near the Madagascar species P. rosea KidL, but has larger 

 flowers and a more leafy stem with only one sheathing bract below 

 the inflorescence.
