8 mm longae, ovarium ovoideum, 1.5 ad 1.8 mm diametro, pu- 
bescente; calyx 1 cm longus, breviter latissime 3-dentatus, den- 
tibus rotundatis, ciliato-laciniatis; corollae tubus 12 mm longus, 
lobis oblongis, cucullatis, 10 mm longis; labellum oblongo-ova- 
tum, 12 mm longum, 6 ad 7 mm latum, sessile, deorsum bicari- 
natum, apice rotundatum; staminoidea lateralia 5 mm longa, 
tenera, corollae lobo postico adnata; filamentum 1.4 cm longum;

Nodoa, McClure 7925, in fruit, 8963 (type), in flower, Octo- 
ber 27, 1921, and May, 1922. In thickets. 
A species apparently allied to Alpinia tonkinensis Gagnep., 
presenting much in common with that species in its inflores- 
cences, the flowers being subcapitately arranged at the apices 
of the primary branches; in its bracteoles; and in its stamin- 
odes being adnate to the upper corolla lobe. It differs in its 
sessile flowers, longer corolla tubes, much longer filaments, 
narrower, differently shaped lip, and in its leaves being some- 
what pubescent beneath.
