20 CXXXIII. ORCHIDEE (ROLFE). [ Liparis. 
linear, obtuse, 2} lin. long. Lip broadly obcordate, crenulate, shortly 
unguiculate, somewhat fleshy, 1? lin. long and the same broad; base 
bituberculate. Column 1 lin. long.—Z. elata var. rufina, Ridl. in Journ. 
Linn. Soc. xxii. 260. 
Upper Guinea. Sierra Leone, Afzelius! Morson! Sugarloaf Mountain, 
Wilford! Scott-Elliot, 3957! Lagos, Barter, 20202! Niger Delta: Nun River, on 
mangroves, Barter, 20122 ! 
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. guineensis, Lindl. 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 14-3 in. long. Scapes 4—1 ft. long. Bracts lanceolate, sub- 
acute, 1-2 lin. long. Dorsal sepal linear-oblong, obtuse, 14 lin. long. 
Petals linear, 14 lin. long. Lip obcordate, shortly unguiculate, minutely 
crenulate, 14 lin. long; base bituberculate. Column # lin. long.—Ridl. 
in Journ. Linn. Soc. xxii. 260; Rolfe in Bolet. Soc. Brot. vii. 236; ix.

Upper Guinea. Sierra Leone, Whitfield ! 
Lower 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, Moie, Leaves elliptical-oblong, subacute 
or obtuse, base attenuate into a short petiole, 24-4 in. long, ł—14 in. 
broad ; petioles 1-14 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, 24-3 lin. 
long ; lateral ones falcate-oblong, obtuse, 2 lin. long. Petals linear, 
subobtuse, 3 lin. long. Lip broadly orbicular-obovate, obtuse or trun- 
cate, 24-3 lin. broad, very shortly unguiculate ; base bituberculate. 
Column 14 lin. long, rather stout.—L. guineensis, Rendle in Journ. 
Bot. 1895, 298 (not Lindl.).

Quite distinct from ZL. 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, 
linguiform, obtuse, entire and fleshy above, carunculate above the
