Rostellum reduced to a very small tooth.—Benth. & Hook, f. Gen. Pl. 
iii. 627. Stenoglottis calcarata, Reichb. f. in Flora, 1865, 180. 
Barlea calcarata, Reichb. f. in Linnea, xli. 54. e 
Lower Guinea, Angola: near Huilla, Welwitsch, 733! not 233 as quoted by 
Reichenbach, 
Reichenbach at first referred this to Stenoglottis, and afterwards made a new genus, 
Barlea, for its reception. Bentham classified it as an anomalous Habenaria, but its 
exact affinity still remains doubtful. 
2. H. zambesina, Reichb. f. Otia Bot. Hamb. ii. 96. Plant 
stout, over 2 ft. high. Leaves cauline, amplexicaul, oblong or ovate- 
oblong, subobtuse or apiculate, 2—44 in. long, 3-1} in. broad, decreasing 
upwards. Racemes cylindrical, 4—8 in. long, dense-flowered. Bracts 
lanceolate or ovate-lanceolate, acuminate, 6-10 lin. long. Pedicels 7-8 
lin. long. Sepals broadly ovate, apiculate, 23-3 lin. long. Petals 
suborbicular-ovate, rather shorter than the sepals. Lip entire, linear- 
oblong, obtuse or apiculate, 3-34 lin. long; spur cylindrical, 14-2 in.
