axillary, 1 lin. long, 1-flowered. Flowers small. Bracts triangular- 
ovate, 14 in. long. Pedicels 24 lin. long. Sepals ovate, acute, larger

Nile Land. British East Africa: Ruwenzori ; head of Butagu valley, 7000 ft., 
Scott-Elliot, 8081! Butagu, 8000 ft., Scott-Elliot, 8100! 
Allied to A. bicaudatum, Lindl., and A, fimbriatum, Rendle. Flowerless speci- 
mens collected at the Nun River, Niger Delta, by Barter! are very similar in habit 
but probably belong to a different species. 
39. A. armeniacum, Lindl. in Bot. Reg. 1839, Misc. 67. Plant 
caulescent, 6 in. high. Roots stout. Leaves distichous, channelled, 
obliquely and acutely bidentate, 3-4 in. long, 4 lin. broad. Spikes 
lateral, horizontal, secund, $ in. long. Bracts broad, truncate, } lin. 
long. Flowers of a uniform apricot-colour. Sepals ovate, acute, 14 lin. 
long. Petals lanceolate, acute, 14 lin. long. Lip trilobed, 14 lin. 
long ; side lobes acuminate ; front lobe triangular, acute; spur pendu- 
lous, clavate, compressed at the base, 34-4 lin. long.—Reichb. f. in 
Walp. Ann. vi. 905; Durand & Schinz, Conspect. Fl. Afr. 39 (excl. 
Angolan plant). 
Upper Guinea. Sierra Leone: cultivated specimens, Loddiges ! 
Flowered in Messrs. Loddiges’ Nursery in 1839. The Angolan plant cited here 
by Reichenbach belongs to the next species. 
_ 40. A. tridactylites, Rolfe in Gard. Chron. 1888, iv. 34. Plant 
with erect or climbing stem, }~2 ft. high and long, very stout roots 
produced at intervals on the stem. Leaves elongate-linear, unequally 
bidentate, 4-8 in. long, 4-7 lin. broad. Racemes axillary, many- 
flowered, somewhat curved, 21-3 in. long. Bracts shortly triangular, 
broadly amplexicaul. Flowers subsecund, 4 lin. diam. Pedicels 2 lin. 
long. Lateral sepals ovate, acuminate; dorsal slightly narrower 
than the lateral, 2 lin. long. Petals lanceolate-linear, acute, 2 lin. 
long. Lip trifurcate, 2 lin. long ; side lobes very slender and recurved ; 
front lobe triangular, acute, straight ; spur slender, 5 lin. long, slightly 
narrowed at the base; lip with a pair of small, fleshy, marginal teeth 
at the base. Column stout, } lin. long, with a pair of small, rounded 
wings at the apex.—A. armeniacum, Reichb. f. in Flora, 1865, 189 (not 
of Lindl.) 
Upper Guinea. Sierra Leone: cultivated specimens, Griffith! Interior of 
W. Lagos, Rowland ! 
Lower Guinea. Angola: Pungo Andongo, shady rocks in the woods of Barranos 
de Tongue, Welwitsch, 685! Princes Island, Barter, 2016! 
Mozamb. Dist. British Central Africa: Nyasaland, Buchanan, 154! 
Near A. bicaudatum, Lindl., but differing, amongst other characters, in the shape 
of the side lobes, Barter’s specimen has no flowers, but is apparently identical. The 
Species is of unusually wide distribution.
