5. R. alcicornis, Kränzl. in Reichb. f. Xen. Orch. iii. 105, t. 258, 
fig. 4. Plant slender, 1 ft. high. Tuber globose, 7 lin. long. Leaves 
linear-lanceolate, acuminate, with about three obtuse sheaths below. 
Spikes 34 in. long, lax, many-flowered. Bracts ovate, acuminate, a 
little longer than the ovary. Pedicels 6 lin. long. Flowers yellow 
marked with brown. Dorsal sepal very broadly ovate, nearly orbicular, 
suddenly acute; lateral larger than the dorsal, semiovate, suboblique, 
acute, reflexed. Petals broader than long, very oblique, cuneate- 
obovate, apiculate, with the upper margin irregularly dentate and 
undulate. Lip simple, from a dilated base, narrowly linear, 34 lin. 
long, shorter than the pedicels; spur slender, recurved at the apex, 
inflated, obtuse, curved. Column very broad; anther arms very large, 
produced in front into acuminate, foliaceous appendages. Stigmatic

39. BONATEA, Willd.: Benth. et Hook. f. Gen. Pl. iii. 628. 
Sepals unequal, free; dorsal erect, lateral oblique, reflexed. Petals 
deeply bipartite; posterior lobe erect, appressed to the margin of 
the dorsal sepal; anterior lobe descending, and simulating a lobe of 
the lip. Lip continuous with the column, produced at the base into a 
more or less elongated spur; limb spreading, base produced into a 
narrow claw, adnate to the base of the lateral sepals, the anterior lobe 
of the petals, and the stigmatic processes, tripartite above with narrow 
lobes. Column short, footless ; clinandrium erect, as long as the anther. 
Anther cells somewhat diverging; apex inferior, prolonged in front 
into channels, confluent with the side lobes of the rostellum; pollinia 
granular, with elongate, curved caudicles, and exserted, naked glands; 
staminodes lateral, small, auriculate. Stigma bipartite, extended = 
front into a pair of elongate, subclavate processes ; rostellum trilobed ; 
middle lobe cucullate, apiculate ; side lobes linear, elongate. Capsule 
oblong.—Terrestrial herbs, with the habit of a large Habenaria. Flowers 
rather large, racemose. Bracts ovate. 
An exclusively Continental African genus of eight species, distinguished from Habe- 
naria by the cucullate middle lobe of the rostellum, and by the union of the base of the 
lateral sepals, the anterior lobe of the petals, and the stigmatic processes with the claw 
` of the lip,
