cited above, which is said to represent this species. A specimen, accompanied by a 

 sketch, from the mountains of tlie Pangani Valley, German East Africa, Kirk I appa- 

 rently belongs here.

The habit of the plant is described from a photograph. A fruiting specimen 

 collected by Scott-Elliot during the Ruwenzori Expedition, without locality, may 

 belong here. 



7. Li. Erythrsese, Rolfe. Stem ;> in. high. Leaves 8-9, linear- 

 oblong, shortly, obtusely, and unequally bilobed, 5-G in. long, 5-6 lin. 

 broad. Raceme arcuate, o in. long, with 2 or 3 broad, basal sheaths 

 G-7 -flowered. Bracts ovate-oblong, subacute. Capsules clavate-oblong, 

 stoutly pedicelled, 1-1^ in. long. — Angrwcum schimperianum, Schweinf.

This is very diflferent from Angrcecum schimjjerianum, Reichb. f., to which it is 

 referred by Schweinfurth ; and although the specimen seen is only in fruit, the habit 

 is so characteristic as to leave little doubt that this is its proper affinity. 



S. Ij. ringenSy Reichb. f. in Gard. Chron. 1878, x. 'l^'o. Plant 

 dwarf, o in. high. Leaves cuneate-oblong, obtusely bilobed, 3 in. long, 

 1 in. broad near the apex. Racemes few-flowered, secund, 3 in. long. 

 Bracts triangular, considerably shorter than the long, pedicelled ovary.

 Petals rhomboid-ligulate, reflexed. Lip rhomboid-lanceolate, with a 

 blunt angle on each side before the mouth of the spur; spur ample,

 1^ in. long. Column short ; rostellum short, not beaked. 



Upper Guinea* Cameroons : cultivated specimens. 



Flowered in the Botanic Garden, Berlin, in 1878. Only known to me from the 

 original description, where it is said to form a connecting link between the L. arcttafa 

 and the L.fiUcornis groups, but to differ from both of them by its short, unbeaked 

 rostellum.

 oblong, shortly and unequally bilobed, 8-5 in. long, j-l| in. broad; 

 lobes rounded. Racemes few-flowered, 2\ in. long. Bracts broadly 

 tubular, 2 lin. long ; apex obtuse and suboblique. Pedicels 4 lin. long.
