Remarkable for its large broad flowers and the prominent lamellae of the lip. Tlie 

 sepals and petals appear to have been white or light yellow, and the lip darker, with 

 very dark purple keels.

 7-nerved, IJ ft. long, 2 J in. broad. Scape 2 J ft. high, with a few long 

 sheaths ; raceme 6 in. long, many-flowered. Bracts linear-lanceolate, 

 |-2J in. long. Pedicels 6-8 lin. long. Flowers yellow, with the side

Reichenbach confused this with a quite distinct S.E. African species (since de- 

 scribed as E. ZeyTieri, Hook. f. Bot. Mag. t. 7330) under the name of E. hicolor, 

 Reichb. f. and Sond. Sir Joseph Hooker renamed it IE. Welwitschii, but that name 

 being preoccupied, the above is substituted. 



42. IS. abyssimca, Reichb. f. in Limicea, xxii. 866. Leaves 

 lanceolate or oblanceolate, acute or subobtuse, 6-12 in. long, 1-2 in.
