long: the central lobe is 8 lines from the back of the crests to the 

 rounded apex, and 7 lines broad. The entrance to the spurred 

 basal sac is guarded by two prominent rounded crests, between 

 which is a less prominent ridge ; these protuberances rapidly pass 

 on the disc into diverging flexuose swollen veins. The blunt spur 

 is 2 lines long, and terminates a sac of about the same length. 

 The column is 4^ lines long by 1^ broad ; the pollinia resemble 

 those of L. mediocris. 



Closely allied to L. vmliocris, but distinguished by its more 

 oblong sepals, petals broader below than above, oblong (not or- 

 bicular) median Hp-lobe with swollen elevated veins, and distinct 

 spur. 



Lissochilils cornigerus, sp. nov. Bracteis cauhnis tubulosis 

 sub apice acuto liberis, racemi triangulari-setaceis caducis, pedi- 

 cellos (cum ovariis) longos baud squantibus ; floribus mediocribus, 

 sepalis 5-nerviis apiculatis, dorsali cuneato-ligulato acuto, lateralibus 

 ligulatis; petalis oblanceolatis obtusis, labelli pandurati auriculis 

 rotundatis ascendentibus, lobo medio crispulo, carinis geminis super 

 calcaris cornuti orificium incrassatis, mediana tenuiore interjecta. 



Hab. Drv grassy plains, 4-5000 ft., Kahimbe, eastern side of 

 Albert Edward Nyanza, Aug. 1894, No. 8031. 



The slender flowering- stem is 2 ft. long, including the 8-flowered 

 raceme (about 5 in.). The stem-bracts are much shorter than the 

 internodes, the lowermost being 2f in. long. The long-pointed 

 floral bracts reach f in. ; the slender pedicels, with ovary, an inch. 

 The sepals are 10 lines long, the dorsal 2i, the lateral 2^ lines 

 broad. The petals are 9 lines long by 4 broad. The blunt lip is 

 9 lines by 6, the basal auricles 3 lines broad ; the horn-like 

 recurved spur is 4 lines long. The column is nearly 4 lines long 

 and 1 broad. 



Near the last species, but differs in its smaller flowers, especially 

 the lip, and marked horn-like spur. 



Var. MINOR. Planta minor, floribus minoribus cum colore 

 saturiori. 



Hab. Buddu (Uganda, W. of Victoria Nyanza), Feb. to Mar. 

 1894, No. 7486. 



The slender flowering-stem is about 21 in. long. The 5-nerved 

 sepals are 9 lines long, the dorsal 2 lines broad, the lateral 2^. 

 Petals 8 by 3 lines ; lip 8 by 6. Spur 3 lines long. 



Also differs from the type in its evidently much deeper-coloured 

 flowers, which moreover appear six months earlier in the year, 

 though tbe two localities are only about 100 miles apart. August, 

 Mr. Scott Elliot tells me, is about the height of the dry season, and 

 February to March about the beginning of the rains. 



Lissochilus gracilior, sp. nov. Planta minor gracilis, floribus 

 minoribus longe pedicellatis, bracteas triangulo-setaceas triplo

 latis, petalis oblongis, labelli pandurati ahs rotundatis, lobo medio 

 late oblongo obtuso, basi super calcar conicum carinis ternis,
