186 The Philippine Journal of Science 1916 
comprises 74 species, and of the list, the following genera have 
no known representatives in the Archipelago: Bouteloua (includ- 
ing Hutriana), Polyschistes (Pentarraphis), Philydrum, Arun- 
dina, Bromheadia, Sebastiana, Eurycoma, Archytaea, Ionidium, 
Anisophyllea, Baeckea, Rhodamnia, Kibessia, Anplectrum, Ma- 
rumia, Pternandra, Allomorpha, Badusa, Pharetranthus (Ptero- 
bium), and Tristicha. 
POLYPODIACEAE 
ACROSTICHUM SPATHULATUM Bory; Presl Rel. Haenk. 1 (1825) 15 “Hab. 
in insula Luzon ? Sorzogon ?” = Elaphogolossum spathulatum (Bory) 
Moore. The Haenke specimen was probably not from the Philippines, but 
from tropical America. The species is unknown as Philippine. 
NEPHRODIUM HIPPOCREPIS Pres] Rel. Haenk. 1 (1825) 35 “Hab. in insula 
Sorzogon” = Aspidium hippocrepis (Jacq.) Sw., a tropical American species. 
Haenke’s specimen labeled “Sorzogon” was probably from South America 
or Mexico, not from the Philippines. 
PTERIS ? ALATA Pres] Rel. Haenk. 1 (1825) 56 “Hab. a in Guajaquil; 
8 in Guajaquil et 7 insula Luzon.” This species of doubtful status may 
have been from Luzon, but was more probably from South America. 
SCHIZAEACEAE 
LYGODIUM VOLUBILE Sw.; Pres! Rel. Haenk. 1 (1825) 73 “Hab. in insula 
Sorzogon.” As this species is supposed to be exclusiely American, Presl’s 
Sorsogon record was probably based on an erroneously labeled specimen. 
The record may have been based on a wrong identification. 
GRAMINEAE 
ANDROPOGON ERIOSTACHYS Pres] Rel. Haenk. 1 (1830) 339 “Hab. in insulis 
Philippinis.” This is a species of tropical America, Andropogon ternata 
Nees var. eriostachyus Hack. Haenke’s specimen certainly never originated 
in the Philippines. 
ARISTIDA LUZONIENSIS Cav. Ic. 5 (1799) 45, t. 470, f. 2. “Habitat in 
. insula Luzon altera ex Philippicis.’”’” No known Philippine species of Aris- 
tida at all approaches the form figured and described by Cavanilles, so that 
it is probable that Nee’s specimen did not originate in the Philippines, but 
in America or possibly in Australia. 
ARISTIDA RIGIDA Cav. Ic. 5 (1799) 44, t. 469, f. 2. “Habitat in insulis 
Philippicis.” Undoubtedly not Philippine. The note given above under 
A. luzoniensis Cav. applies here. 
ARISTIDA MURINA Cav. Ic. 5 (1799) 44, t. 469, f. 1. “Habitat in Mindanao 
insula prope Samboangan [Zamboanga].” This is most certainly not a 
Philippine form. The note given above under Aristida luzoniensis Cav. ap- 
plies here. 
AVENA STERILIS Linn.; Pres] Rel. Haenk. 1 (1830) 253 “Hab. in insulis 
Philippinis.” The Philippine record was certainly based on an erroneously 
localized plant. The genus Avena is unknown in the Phiilppines except for 
occasional specimens of A. sativa from introduced grain. 
BOUTELOUA SIMPLEX Lag. in varied. Cienc. 24 (1805) 141 “Peruv.; Ins.
