ORCHIDACEAE 115 
orchids Blanco’s description applies unmistakably to Luisia. His 
material was from Angat, Bulacan Province, Luzon. 
Illustrative specimen from Calumpit, Bulacan Province, Luzon, 
January, 1915 (Merrill: Species Blancoanae No. 945). 
PHALAENOPSIS Blume 
PHALAENOPSIS AMABILIS Blume; Blanco Fl. Filip. ed. 2 (1845) 592 
(Phalenopsis amabile) ; ed. 8, 3 (1879) 41. 
~The form Blanco described was doubtless the one that was 
described from Philippine material as Phalaenopsis aphrodite 
Reichb. f. It does not appear to be specifically distinct from 
Blume’s species. 
SARCANTHUS Lindley 
Cypripedium lineari-subulatum Llanos Frag. Pl. Filip. (1851) 99 (sp. 
' nov.); F.-Vill. & Naves in Blanco F. Filip. ed. 3, 4' (1880) 76= 
- SARCANTHUS DEALBATUS (Lindl.) Reichb. f. 
Llanos’s description, although fairly long, is exceedingly un- 
satisfactory, and, in considering the species, Naves, Novis. App. 
(1880) 251, retains it under Cypripedium with the following 
statement: ‘valde dubium, ex descriptione potius Cleisostoma 
longifolium Teysm. et Binnend. nondum rite observavi.” From 
the description alone it is absolutely impossible to interpret 
the species. A botanical exploration of the region about Calum- 
pit has yielded but three species of orchids so far, and among 
them the species distributed herewith which agrees with Llanos’s 
description as to habitat (on mango trees), as to size and char- 
acters of the leaves, and, at least in part, with the description 
of the stems, inflorescence, flowers, and fruits. I have abso- 
lutely no doubt that Sarcanthus dealbatus is the species Llanos 
attempted to describe. The species, although not common, is 
widely distributed in the Philippines at low altitudes, extending . 
from central Luzon to southern Mindanao. 
Tllustrative specimen from San Miguel, near Calumpit, Bula: 
can Province, Luzon, January, 1915, growing on mango trees 
(Merrill: Species Blancoanae No. 774). 
' CLEISOSTOMA Blume 
Epidendrum lineare Blanco Fl. Filip. (1837) 644; ed. 2 (1845) 449; ed. 
3, 3 (1879) 44, non Linn. =CLEISOSTOMA BICOLOR Lindl. & Paxt. 
Naves reduced this to Cleisostoma ionosmum Lindl., but Blan- 
co’s description conforms much more closely to C. bicolor Lindl. 
& Paxt. than to the former; the latter is, moreover, common 
and widely distributed in the regions from which Blanco secured 
his botanical material and is an orchid that he scarcely would 
ve overlooked, while the former is apparently rare.
