Closely allied to the Tropical American L. elata^ Lindl., of which Ridley makes it 

 a variety, but differs in its proportionately shorter, crenulate and rather more fleshy 

 lip. It is also near the Indian L. bituberculata, Lindl. Barter notes the flowers as 

 " deep red," but a plant from Mr. Scott- Elliot, which flowered at Kew, had green 

 sepals and petals and a dull purple lip. Ridley refers Wilford's specimens to the 

 following species, but both flowers and leaves agree with the present one. 



2. L. ^ineensis, Lmdl. Bot. Reg. t. 1671. Pseudobulbs oblong 

 or sometimes hardly developed, 4-5-leaved. Leaves elliptical or ovate- 

 oblong, subobtuse or apiculate, blade 3-7 in. long, 1-3 in. broad: 

 petiole lJ-3 in. long. Scapes J-1 ft. long. Bracts lanceolate, sub- 

 acute, 1-2 lin. long. Dorsal sepal linear-oblong, obtuse, 1| lin. long. 

 Petals linear, If lin. long. Lip obcordate, shortly unguiculate, minutely 

 crenulate, 1 J lin. long ; base bituberculate. Column f lin. long. — Ridl.

Upper Guinea. Sierra Leone, Whitfield ! 

 Itower Guinea. Princes Island, Barter, 1980 ! Quintas, 8 ! 

 Whitfield's original specimen from Sierra Leone has green flowers, but Barter's 

 from Princes Island are marked " Flowers purple," yet I fail to distinguish them. 



3. L. ruwenzoriensis, Rolfe. Leaves elliptical-oblong, subacute 

 or obtuse, base attenuate into a short petiole, 2J-4 in. long, f-lj in. 

 broad ; petioles 1-1 J in. long. Scape 8-9 in. high ; raceme 3—4 in. 

 long. Bracts lanceolate to ovate-lanceolate, acuminate, 3-5 lin. long. 

 Pedicels 4-5 lin. long. Dorsal sepal oblong-linear, subobtuse, 2J-3 lin. 

 long ; lateral ones falcate-oblong, obtuse, 2 lin. long. Petals linear, 

 subobtuse, 3 lin. long. Lip broadly orbicular-obovate, obtuse or trun- 

 cate, 2J-3 lin. broad, very shortly unguiculate ; base bituberculate. 

 Column IJ lin. long, rather stout. — L. guineensis, Rendle in Journ.

Quite distinct from L. guineensis, Lindl,, to which it has been referred. Fruiting 

 specimens from between Kondowa and Karonga, on the west of Lake Nyasa, Whyte ! 

 apparently represent this or an allied species. 



4. L. abyssinica, A. Rich. Tent. Fl. Abyss, ii. 281. Pseudobulbs 

 covered with loose sheaths, 2-3-leaved. Leaves oval or oval-oblong, 

 acute, flat, with sheathing base. Scapes few-flowered. Bracts oval- 

 lanceolate, acute, equalling the ovary. Flowers purple. Dorsal sepal 

 lanceolate, subobtuse; lateral ones half oval, obtuse, united to above 

 the middle. Petals linear. Lip with broad semicanaliculate base,
