oboval, obtuse, stout, connivent, 14—2 lin. long, nearly as broad. Lip 
transversely oval, or orbicular if flattened out ; apex rounded, concave ; 
spur nearly straight, the upper half slightly inflated, 3 lin. long. 
Column stout; anther retuse ; gland linear.—Angrecum cephalotes, 
Kriinzl. in Mitth. Deutsch. Schutzgeb. ii. (1889), 156. 
Upper Guinea. Cameroons, Braun. 
Only known to me from the original description. Said to be allied to Z. capitata, 
Reichb. f., but only half as large. A fine fruiting specimen from the Cameroon 
Mountains, 5000 ft., Mann, 2123! may possibly belong here. 
46. L. Batesii, Rolfe. Stem stout, erect, 4—1 in. long. Leaves 
ensiform, compressed, curved, obtuse, 1-24 in. long, 3-4} lin. broad. 
Scapes slender, suberect, dense, many-flowered, secund, 2}—6 in. long. 
Bracts broadly ovate, apiculate, sheathing below, ł}-1 in. long. Pedicels 
1 iin. long. Flowers white. Sepals and petals oblong, obtuse, 14 lin. 
long. Lip oblong, obtuse, slightly concave at the base, 14 lin. long; 
spur somewhat inflated, lanceolate-oblong, subacute, 1} lin. long. 
. Column stout, ? lin. long.

Lower Guinea. Gaboon: Como River, Bates, 463 ! 
47. L. Zenkeri, Kränzl. in Engl. Jahrb. xix. 252. Plant very 
small, with a short, stout stem. Leaves ensiform, short, 13-2 in. long, 
2 lin. broad; apex unequal, subacute. Racemes erect, a little longer 
than the leaves, with retuse, ochreate sheaths at the base. Bracts 
broadly triangular, acute, half as long as the flowers. Flowers 1 lin. 
diam. Dorsal sepal oblong, obtuse, with a thickened apiculus ; lateral 
equal, carinate ` apex biapiculate, one point being in front of the other. 
Petals a little broader than the sepals, more slender, very obtuse. Lip 
ovate-oblong, obtuse, a little contracted above the base ; spur as long as 
the limb, inflated, slightly compressed, obtuse, incurved. Column stout, 
anther elongate, retuse ` pollinia with 2 slightly thickened and excavate 
stipites. i 
Upper Guinea. Cameroons: Yaunde, on high trees of the primæval forest, 
Zenker, 623. 
Said to be one of the smallest species of the genus, with the habit of Angraecum 
Maude, Bolus, which it closely resembles in habit. I have not seen it. A fruiting 
specimen from Sugarloaf Mountain, Sierra Leone, Barter ! apparently represents an 
allied species. 
48. L. iridifolia, Rolfe. Stem short and stout, 4 in. long., Leaves 
ensiform, compressed, curved, obtuse, }-1 in. long. Scapes suberect, 
slender, 1$-2 in. long, 8-12-flowered, with a few oblong, apiculate 
sheaths near the base. Bracts triangular-oblong, subacute or apiculate, 
1 lin, long. Capsules elliptic-oblong, 24 lin. long.— Angraecum? aff.
