POLYGONACEAE 
POLYGONUM Linnaeus 
POLYGONUM BARBATUM Linn. Sp. Pl. (1753) 362. 
G. E. S. 17, locally known as mamaca. 
I can see no reason for distinguishing this form from the widely dis- 
tributed and somewhat variable Polygonum barbatum Linn. It is doubtless 
the species recorded by Safford p. 358, as possibly being the above species. 
Tropical Asia to Malaya. 
ANTIGONON Endlicher 
ANTIGONON LEPTOPUS Hook. & Arn. Bot. Beech. Voy. (1841) 308, 
t. 69. 
G. E. S. 228, locally known as cadena de amor. 
A native of tropical America, now widely distributed in cultivation. 
CHENOPODIACEAE 
CHENOPODIUM Linnaeus 
CHENOPODIUM ALBUM Linn. Sp. Pl. (1753) 219; Safford 224. 
G. E. S. 416, a weed. 
Widely distributed in the temperate and tropical regions of both hemis- 
pheres, probably originally European. 
CHENOPODIUM AMBROSIOIDES Linn. Sp. Pl. (1753) 219; Safford 224. 
G. E. S. 349, locally known as apasotes. 
A native of Mexico, now widely distributed in the warmer parts of both 
hemispheres. 
AMARANTHACEAE 
ACHYRANTHES Linnaeus 
oT. ACHYRANTHES ASPERA Linn. Sp. Pl. (1753) 204; Safford 174. 
G. E. S. 188. 
A weed of wide tropical distribution, probably originating in the eastern 
hemisphere. It is suspected that the specimen collected in the Marianne 
Islands (and probably in Guam) by Gaudichaud, and reported by Moquin ™ 
as Achyranthes fruticosa, is A. aspera Linn. 
AMARANTHUS Linnaeus 
AMARANTHUS SPINOSUS Linn. Sp. Pl. (1753) 991; Safford 180. 
G. E. S. 293, “widely distributed”. 
All tropical countries, where native uncertain. 
AMARANTHUS TRICOLOR Linn. Sp. Pl. (1753) 989. 
G. FE. S. 862, local name enmosa viaja. 
The distribution and status of this species is uncertain due to the very 
complicated synonymy. The Linnean designation Amaranthus tricolor has 
2 * DC. Prodr. 13° (1849) 314.
