206 CXXXIII. ORCHIDEÆ (ROLFE). | Podandria. 
lobe linear-subulate, with incurved apex; side lobes short and broad, 
with bidentate apex. 
A West African monotype, somewhat resembling Habenaria in habit, but remark- 
able for its enormously elongated anther and long narrow segments. The stigma 
resembles Platanthera, but is guarded on either side by the enlarged side lobes of the 
rostellum, which are free from the anther channels. 
1. P. macrandra, Rolfe. Plant 3-13 ft. high. Leaves 4-7, 
radical, petioled ; blade elliptic-oblong, acute, 2-5 in. long, 2-2 in. 
broad; petioles 1-2 in. long. Racemes with 2-9 large flowers. 
Bracts ovate-lanceolate, acuminate, 1-1} in. long. Pedicels 1-14 in. 
long. Dorsal sepal linear-lanceolate, subacuminate, 14 lin. long; 
lateral linear, acuminate, 15 lin. long. Petals simple, filiform- 
setaceous, acuminate, 14 in. long. Lip tripartite; lobes linear-filiform, 
7-8 lin. long, subequal or the front lobe slightly longer than the side; 
spur 24-3 in. long, slender below, slightly thickened above. Stigmas 
sessile, nearly confluent. Anther cells 2 lin. long, situated at the apex 
of a narrow stipes, 7-8 lin. long, free from the side lobes of the 
rostellum at the base; staminodes oblong, erect, ł lin. long. Ros- 
tellum trilobed; side lobes broadly oblong, bidentate, 1 lin. long; 
front lobe linear-subulate, curved at the apex, 14 lin. long.—Habe- 
naria macrandra, Lindl. in Journ. Linn. Soc. vi. 139; Reichb. f. in 
Flora, 1865, 179; Krinzl. in Engl. Jahrb. xvi. 161.

Pl. iii. 624, in part. 
Sepals unequal, free; lateral more or less spreading or reflexed. 
Petals simple or deeply bilobed, usually narrower than the dorsal 
sepal, and appressed to it, forming a galea, or the posticous lobe so 
appressed, and the anticous descending, and simulating a lobe of 
the lip. Lip continuous with the column, often shortly adnate to it, 
produced at the base into a short or much elongated spur; limb 
spreading or pendulous, narrow or broad, undivided or trilobed; side 
lobes sometimes fimbriate or pectinate. Column short, footless; 
clinandrium erect, short or scarcely as long as the anther. Anther 
cells parallel or diverging; apex inferior, short and adnate or free, 
elongate, and horizontal, or descending in slender channels on the 
margins of the side lobes of the rostellum; pollinia granular, with 
short or elongate caudicles, and exserted, naked gland ; staminodes 
lateral, small, rounded or auriculate. Stigma bilobed, or extended into 
two short or elongate, often clavate, papillose processes; rostellum 
trilobed; middle lobe subulate or tooth-like, situated between the 
anther-cells; side lobes much longer, and acting as carriers for the 
eaudicles of the pollinia. Capsule ellipsoid or oblong, sometimes
