12. Thrixspermum Hystrix (B/.) Reichenbach 
jfiius in Trans. Linn. Soc. 30 (1874) 186, 145—J.J. 
Smith in Fl. Buitenz. 6 (Orch. Java) (1905) 577 and in 
Figuren-Atlas pt. 5 (1912) fig, CDX XXITI. 
Dendrocolla Hystriv Blume Bijdr. (1825) 291. 
It is with some misgiving that the present specimen 
is referred to 7°. Hystrix. The petals and sepals of the 
single flower present have been broken, but the lip is in 
good condition. The lip corresponds very well with the 
figure given by Smith and until more complete material 
is available it seems best to refer the specimen here, even 
though dubiously. I have seen no herbarium material 
referable to 7. Hystriv. 
Attention should be called to the similarity of 7°. 
adenotrichum Schltr. to the present specimen.

13. Thrixspermum Wenzelii 4 mes Orch. 5 (1915) 
209. 
This species is cited by Ames (Orch. 5 (1915) 209) 
as occurring in Leyte, Palawan and Luzon and again it 
is attributed to Luzon, Leyte, Palawan, Mindanao and 
Basilan by Ames in Merrill Enum. Philipp. Flow. PI. 
1 (1925) 406. The distributions given above are, I believe, 
based on an aggregate. 
The specimens from Luzon and Leyte belong here 
in part, some of them belonging to 7. Amesianum L.. 
Wms. The specimen from Palawan is possibly unde- 
scribed and may belong to Schlechter’s proposed section 
Katocolla. The specimen from Basilan belongs to the 
following species, 7’. angustatum L.Wmums. 
Luzon, Leyte. 
These two collections seem to differ somewhat from the others.
