TAENIOPHYLLUM Blume 
Taeniophyllum is one of those perplexing genera of 
orchids of which the collector usually finds but a few 
plants. The flowers are delicate and apparently never pro- 
duced abundantly; hence material finding its way into 
herbaria is often indeterminable. 
In the Philippine Islands the genus is represented by 
six described species. The author believes that this num- 
ber might be doubled, for there are specimens in the 
Ames Herbarium which seem to indicate that there may 
be an equal number of undescribed species in the Philip- 
pines. ‘The material at hand is adequate for the descrip- 
tion of two of these species, but it is thought advisable 
to await more complete material before attempting to 
identify the others. 
The species of T'aentophyllum previously known to be 
natives of the Philippines have all belonged to the sub- 
genera HMutaeniophyllum and Microtatorchis. Another 
subgenus is proposed, to which a new Philippine species 
and two old species are referred.
