tuse,emarginate, the apex fleshy-thickened and obscurely 
pubescent, disc with a V-shaped callus; spur 8.5-5 mm. 
long and 1.5—2 mm. in diameter, straight, the tip simple, 
acute or obtuse, with two stipitate glands near the mid- 
dle inside. Column of the genus. 
British New Guinea: forming open ground cover in forest on flood 
plains, Fairfax Islands, Lower Fly River, flowers white, October 1936, 
Brass 8193 (Tyrer in Herb. Ames); Matap, Morobe District, alt. 5000- 
6000 ft., flowers white, February 6—April 6, 1940, Clemens 11252. 
Erythrodes adscendens and E. sutricalcar, the species 
described below, are unique among the species of Ery- 
throdes in New Guinea (if not in all of Oceania) in hav- 
ing a spur that is not bilobed or didymous. These species 
add further strength to Ames’ contention (Orch. 7 (1922) 
63-66) that Physurus (neotropic) and EHrythrodes (pale- 
otropic) are synonymous. 
There are apparently no near allies of Hrythrodes ad- 
scendens in the immediate area of Oceania, except HH. 
sutricalear. Superficially the species somewhat resembles 
Erythrodes platensis (Haum.) L. Wms. from South 
America. 
It is with some hesitation that we unite the two col- 
lections cited above as one species. The Clemens speci- 
men is the smaller of the two, with smaller leaves and 
shorter stems, but has slightly larger flowers. The flower 
parts seem to be essentially the same as those in the Brass 
collection. ‘The Brass collection comes from near sea- 
level, while Mrs. Clemens found the plants at 5000-6000 
feet altitude.
