136 SPECIES BLANCOANAE 
the only region near Manila where it has been found is Pasig, 
the town from which Blanco secured his specimens. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
November, 1914 (Merrill: Species Blancoanae No. 141). 
Polygonum bellardi Blanco Fl. Filip. (1837) 314 (Poligonum), ed. 2 (1845) 
219; ed. 3, 2 (1878) 45, non All.=POLYGONUM TOMENTOSUM 
Willd. 
Blanco’s conception of Allioni’s species was reduced by Paw 
nandez-Villar to Polygonum orientale Linn., while in. Index 
Kewensis it is reduced to Polygonum persicaria Linn., both of 
which are wrong; it is manifestly referable to P. tomentosum 
Willd. The species is fairly common along the banks of the 
Pasig River, near Manila. 
Illustrative specimen from the Barrio of Pineda, Pasig, Rizal 
Province, Luzon, November, 1914 (Merrill: Swectés cpacerepucoerd 
No. 191). 
RUMEX Linnaeus 
Rheum muricatum Blanco FI. Filip. (1837) 327 (sp. nov.) —Rumex muri- 
eatus Blanco op. cit. ed. 2 (1845) 195 (comb. nov.); ed. 3, 1 (1877) 
346=RUMEX MARITIMUS Linn. 
This reduction was made by Fernandez-Villar and is ap- 
parently the correct disposition of the form that Blanco de- 
scribed. I have seen no Philippine specimens of it, Blanco’s 
description having been based on introduced and cultivated 
plants. 
CHENOPODIACEAE 
CHENOPODIUM Linnaeus 
CHENOPODIUM AMBROSIOIDES Linn.; Blanco FI. Filip. (1837) 200; ed. 
2 (1845) 140; ed. 3, 1 (1877) 253, t. 69. 
The Linnean species was correctly interpreted by Blanco. It 
is known throughout the Philippines as aposotis. It was in- 
troduced from Mexico by the Spaniards for medicinal purposes 
and is now widely distributed in the Archipelago in cultivation 
and as a naturalized plant. 
Illustrative specimen from Pasay, Rizal Province, Luzon, 
April, 1914 (Merrill: Species Blancoanae No. 244). 
AMARANTHACEAE 
DEERINGIA R. Brown 
Celosia baccata Retz.; Blanco Fl. Filip. (1837) 193=Deeringia celosioides 
R. Br.; Blanco op. cit. ed. 2 (1845) 135; ed. 3, 1 (1877) 244, t. 286=

This species, correctly interpreted by Blanco, is common and
