lateral ones only near the tip. Lip short, bifid to the mouth of the tube, 
the lobes linear-oblong, truncate, glabrous, adnate to the linear, acute 
staminodes which are nearly as long, and to the stamen-filament which 
is linear, glabrous and rather short. Anther oblong, with a small semi-

Schumann was unable to find the type of this species, and the description is too 
imperfect to identify it. 
15. COSTUS Linn. 
Tall herbs, the stems often spiral, sometimes branched. Leaves lan- 
ceolate, shortly petioled, the ligule forming a complete ring. Flower- 
spike terminal or basal. Bracts stiff, often spiny. Calyx tubular, 3- 
lobed. Corolla-tube broad-funnel-shaped, as long as the calyx-tube, the 
lobes large, lanceolate or oblong. Lip large, obovate, usually entire, 
broadly trumpet-shaped. Staminodes absent. Stamen very broad and 
thin, the connective large, acute or curved upward. Anther-cells linear. 
Fruit a woody capsule splitting on one side. Seeds numerous, angled.
