ORCHIDACE.E 



78. PHALSENOPSIS Bl. 



This is a genus of showy orchids which is of horticultural impor- 

 tance and consequently very difficult to systematize. Numerous 

 varieties have been described for horticultural purposes which de- 

 pend largely on color, size, and form, characteristics impossible 

 to distinguish in dried material. In the following list no attempt 

 has been made to differentiate between forms which are purely 

 horticultural. An instructive paper on Phalsenopsis was published 

 by R. A. Rolfe in the August number of the Orchid Review for 

 1905, in which references are made to Philippine species. I have 

 marked with an asterisk those species that have not been repre- 

 sented in collections made for the Bureau of Science, and which 

 are known to me only through cultivated specimens. 



1. Phalsenopsis amabilis Lindl. va?\ Aphrodite Ames Orchi- 

 dace^e 2 : 226. This variety is regarded as a distinct species by 

 several authorities, but on characteristics which appear to me 

 negligible. For synonymy and varieties Orchidace^e, volume 2, 

 pages 224 to 229, should be studied. In Petiver's Gazophyla- 

 cium, plate 103, fig. 10, this species is represented. Probably from 

 the Camelli specimens referred to in Ray's Historia Plantarum. 



Luzon, Mindanao, Palawan, Lambucan (like var. Ri?nestadtiana,^owers 



9.5 cm. across). 



*2. Phalsenopsis Boxallii Reichb. f. in Gard. Chron. (1883) 1 : 

 274. See also Gard. Chron. (1886) 2 : 276. Related to P. Mannii 

 Reichb. f. 



3. Phalsenopsis equestris (Schauer) Reichb. f. Linnsea 22 : 864. 

 P. rosea Lindl., P. Esmeralda Cogn. 

 Luzon, Mindanao, Bohol, Panay. 



*4. Phalsenopsis fuscata Reichb. f. in Gard. Chron. (1874) 2 : 6.
