40. POLYGONUM LACERUM, H.B.K. Nov. Gen. ii. 179 (1817). 
Mountains of Peru (according to Humboldt); Bolivia: La 
Paz, 10,000 ft. (Bang, 130), Cochabamba, 7,000 ft. (Bang, 1057); 
Western Texas: Maronllas Creek (Havard, 112). 
According to a note in DeCandolle’s Prodromus, Meisner seems 
to doubt the validity of this species, saying that fragments of 
Humboldt’s specimens in Kunth’s Herbarium are hardly sufficient 
to distinguish it from related plants. A very short and indefin- 
ite description is given, but the specimens of Mr. Bang agree 
reasonably well with it and are from the same region in which P. 
lacerum is said to occur. 
As I have not seen Humboldt’s specimen, I prefer to refer 
Mr. Bang’s to P. /acerum rather than to describe them as new. ' In 
Dr. Rusby’s distribution of Mr. Bang’s collections this plant was 
referred to P. striatum which proves to be incorrect. Havard’s 
112 from Western Texas belongs here, and interesting as this 
may be, it is not surprising, for, as the flora of the Andes of 
South America is gradually brought to light, the relation between 
_ it and that of the southwestern United States is more clearly seen
