STANDLEY: SPECIES OF AMARANTHUS 507 
apiculate, thin and scarious except along the single green nerve; 
sepals of the pistillate flowers 2 mm. long, spatulate, or narrowly 
oblong and narrowed toward the base, broadly obtuse to acutish, 
glabrous, rather thick and firm, much thickened and united at the 
base, the midnerve usually excurrent; stamens 5; style branches 
3, slender, elongate, divaricate; utricle obovoid, about equaling 
the sepals, thin-walled, nearly smooth, circumscissile; seed rotund, 
black and shining, about 1 mm. in diameter. 
Type in the U.S. National Herbarium, 463205, collected in the 
Vicinity of La Barra, 8 kilometers east of Tampico, Tamaulipas, 
Mexico, at sea level, February 1-8, 1910, by Dr. Edward Palmer 
(266). Additional material of the same collection is mounted on 
sheet 463206. 
In general appearance this is similar to Amaranthus Greggii S. 
Wats., a species with indehiscent fruit. The form of the fruit 
and bracts would suggest a relationship with A. Torreyi, but that 
has erect stems, narrower leaves, larger flowers, and narrow 
bracts, while the form of the inflorescence is very unlike in the 
two species. 
AMARANTHUS GREGGII S. Wats. Proc. Amer. Acad. 12! 274. 1877 
Watson based this species upon specimens collected by Gregg 
in Mexico, at the mouth of the Rio Grande, in 1848 or 1849. 
Uline and Bray * in their monograph of the North American 
species of Amaranthus say: ‘‘The fact that but one locality has 
ever been reported, and that only the pistillate flowers and the 
upper part of the plant are in existence, places this species on a 
rather perilous footing.” Mr. G. L. Fisher, however, has re- 
collected the plant recently at Galveston, Texas. On September 
8, 1912, he gathered pistillate specimens along the beach at 
Galveston (102), and on September 1, 1913 he revisited the 
locality, securing both staminate and pistillate plants (605, 
612). His specimens agree very well with the type in the Gray 
Herbarium, which the writer has examined through the courtesy 
of Dr. B. L. Robinson. Mr. Fisher states that the plant is abun- 
dant on sand along the Gulf shore about 400 feet from water. 
The new locality represents a considerable extension of range for 
this species which no doubt will be found at intervening points 
along the Texan coast.
