116 SPECIES BLANCOANAE 
Illustrative specimen from Rizal Province, Luzon, October, 
1916 (Merrill: Species Blancoanae No. 1020). 
AERIDES eres, 
Aerides maculatum Llanos Frag. Pl. Filip. (1851) 93 (sp. nov.); F.-Vill. 
& Naves in Blanco FI. Filip. ed. 3, 4* (1880) 72, t. 409, non Buch.- 
Ham=AERIDES QUINQUEVULNERA Lindl. 
Naves reduced Aerides maculatum Llanos to Vanda lissochiloi- 
des Lindl.—Vandopsis lissochiloides Pfitz., manifestly an impos- 
sible reduction, although Vandopsis lissochiloides Pfitz. grows 
in the Philippines. Llanos’s description does not apply to Van- 
dopsis lissochiloides in any particular and is certainly an 
Aerides, identical with A. quinquevulnera Lindl. This species 
is of wide distribution at low and medium altitudes in Luzon; 
it is one of the few orchids to be found in Calumpit, the locality 
where Llanos secured the specimens he described. 
Illustrative specimen (a topotype) from Calumpit, iulseest 
Province, Luzon, January, 1915, growing on mango trees (Mer 
rill: Species Blancoanae No. 789). 
TRICHOGLOTTIS Blume 
Synptera subviolacea Llanos Frag. Pl. Filip. (1851) 98 (gen. et. sp, nov.) ; 
F,-Vill. & Naves in Blanco Fl. Filip. ed. 3, 4% (1880) 75, t. 348 (as 
T. rigida Blume) = TRICHOGLOTTIS SUBVIOLACEA (Llanos) comb. 
nov. (Trichoglottis bataanensis Ames). 
This genus and species was reduced by Naves to Trichoglottis 
retusa Bl., which, although it occurs in the Philippines, does 
not at all agree with Llanos’s description. In Index Kewensis 
it is reduced to Cleisostoma subviolaceum Reichb. f., a species 
based on Philippine material but published with no reference 
whatever to Llanos’s Synptera subviolacea, while the two descrip- 
tions apply to very different species. Llanos’s specimens were 
from Calumpit, a town at sea level a short distance north of 
Manila and a region very poor in orchids. Trichoglottis bata- 
anensis Ames is the only species known to me that occurs at 
low altitudes in regions like Calumpit that at all agrees with 
Llanos’s description. The description is vague and imperfect, 
but is manifestly that of a Cleisostoma. The leaves are not 
“aovadas,” but this term is modified by Llanos by the addition 
“alargadas ;” otherwise the description applies very closely, and - 
as Trichoglottis bataanensis Ames is widely distributed at low 
altitudes in central Luzon, there is every reason to believe that . . | 
this is the species that Llanos intended.
