Mozamb. Dist. British Central Africa: Nyasaland, Buchanan ! 
Remarkable for its large broad flowers and the prominent lamelle of the lip. The 
sepals and petals appear to have been white or light yellow, and the lip darker, with 
very dark purple keels.

7-nerved, 14 ft. long, 2} in. broad. Scape 2} ft. high, with a few long 
sheaths; raceme 6 in. long, many-flowered. Bracts linear-lanceolate, 
321 in. long. Pedicels 6-8 lin. long. Flowers yellow, with the side 
lobes of the lip deep purple. Sepals and petals elliptical-oblong, acute, 
11-13 lin. long. Lip trilobed, 9-10 lin. long; side lobes suborbicular-

Mag. sub t. 7330 (not Rolfe).

Reichenbach confused this with a quite distinct S.E. African species (since de- 
scribed as E. Zeyheri, Hook. f. Bot. Mag. t. 7330) under the name of E bicolor, 
Reichb. f. and Sond. Sir Joseph Hooker renamed it E. Welwitschii, but that name 
being preoccupied, the above is substituted. 
42. E. abyssinica, Reichb. f. in Linnea, xxii. 866. Leaves 
lanceolate or oblanceolate, acute or subobtuse, 6-12 in. long, 1—2 in.
