5. R. alcicomiSy Krdnzl in Reichh. 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 3 J 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, 3|^ 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 

 processes similar, diverging, subclavate, subfalcate, with narrow stig- 

 matic margins.

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 ; poUinia 

 granular, with elongate, curved caudicles, and exserted, naked glands ; 

 staminodes lateral, small, auriculate. Stigma bipartite, extended in 

 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 Hahe- 

 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.
