NOMENCLATORIAL NOTES XIII 
BY 
CHARLES SCHWEINFURTH 
Erythrodes santensis ( Kriinzl.) C. Schweinfurth 
comb, nov. 
Physurus santensis Kriinzlin in Kungl. Svensk. Vet. 
Akad. Handl. 46 (1911) 89, t. 7, fig. 6. 
Since Physurus L.C.Rich., a nomen nudum, is syn- 
onymous with Hrythrodes Bl., the new combination is 
necessary. 
It is evident that the artist’s drawing (l.c.) represents 
the natural forcipate position of the apical arms of the 
lip, whereas in the forcibly expanded position these arms 
are reversed and assume a retrorsely lunate position. 
A collection from Colombia appears to be referable to 
this species which was described from Sao Paulo, Brazil. 
These plants differ from the typical form in having broad- 
er leaves (up to about 20 mm. wide) and in having larger 
petals. 
CoLompia: Intendencia El Choc6, in dense forest south of Rio Con- 
doto, between Quebrada Guarapo and Mandinga, at 120-180 meters 
altitude, April 22, 28, 1939, E.P. Killip 35674. 
Malaxis liparidioides (Finet) C. Schweinfurth 
comb, nov. 
Microstylis iparidioides Finet in Bull. Soc. Bot. France 
55 (1908) 383, t. 10, figs. 1-10 
As the concept Microstylis Nutt. ex Lindl. is synony- 
mous with the earlier name Malawis Soland. ex Sw., the 
new combination is required. 
This species, which was described from Ecuador and 
Peru, is now recorded from Colombia. 
CoLompra: Dept. El Valle, El Silencio, Yanaconas, at 1900-2200 
meters altitude, terrestrial in dense forest, flowers green with white 
lip, February 28, 1939, FE. P. Killip & Hernando Garcia 33775.
