156 BOTANY OF THE VOYAGE OF THE SULPHUR. 
This common American form is the one described by Miquel, Linnea, 18, 
p- 244, under the name of B. surinamensis. We have it from numerous localities, 
extending from the Southern United States and Mexico to Brazil and Peru, and 
the species, including probably B. erecta and B. decumbens of Linneus, appears 
to extend over the islands of the Pacific, perhaps even to East India. It is gene- 
rally smooth, or nearly so, with the exception of a few long hairs on the margins of 
the leaves; the panicle has very numerous slender branches; the flowers are 
solitary, or three or four together on very short pedicels; the fruit angular, 
turbinate, from a line to a line and a half in length, and very variable in the 
degree of glandular pubescence; the perigon red, campanulate, and small, and 
very different in this respect from that of B. scandens, B. repanda, and B. litioralis, 
in which it is infundibuliform, with ratheralongtube. The bractes in Boerhaavia 
are not more decidedly collected into an involucre than in Pisonza, although on 
account of a supposed difference in this respect, the two genera are placed by 
Endlicher and others in different subdivisions of the order Nyctaginee. 
733. BomrHAAavia viscosa, Lag.—Vahl. Enum. 1. p. 288.—Guayaquil. 
This is very near to B. polymorpha, but the leaves are broader and more 
blunt, the whole plant thickly clothed with a viscid down, and the flowers crowded 
into a few dense heads.
