508 STANDLEY: SPECIES OF AMARANTHUS 
The species is very distinct, differing from most of its relatives 
in its tough-walled, indehiscent fruit. The branches are nearly 
a meter long or shorter, succulent, sparingly branched, and pro- 
cumbent or ascending. Watson described the pistillate sepals as 
acute, but in both the type and the Texan specimens the inner 
ones are rounded or obtuse, while the outer ones are acute, or 
frequently obtuse. 
AMARANTHUS BRACTEOSUS Uline & Bray, Bot. Gaz. 19: 314. 1894 
Amaranthus viscidulus Greene, Pittonia 3: 344. 1898. 
The type of A. bracteosus (in the Gray Herbarium) was col- 
lected by Fendler (735), probably near Santa Fe, New Mexico. 
Amaranthus viscidulus was based upon Wooton’s 300 from the 
White Mountains, New Mexico, the specimens having been 
collected at Gilmore’s Ranch on Eagle Creek. Upon a superficial 
examination the two appear distinct, but more careful comparison 
has convinced the writer that they are the same species. The 
type of A. bracteosus appears to be a plant grown in wet soil, for 
it is very stout and has large leaves, while very little pubescence 
is present. The type of A. viscidulus is a smaller plant with a 
more slender stem, smaller leaves, and abundant viscid-villous 
pubescence. Both are very unlike any other American species. 
They agree perfectly in the peculiar form of the bracts and fruit, 
and in having the petioles longer than the leaf blades. These 
differences are probably correlated with habitat. A greater 
amount of moisture would be expected to produce a larger, less 
pubescent plant like A. bracteosus. No specimens corresponding 
to Fendler’s plant have been collected recently in New Mexico, 
although several botanists have worked in the region from which 
it came. On the other hand, Amaranthus viscidulus has been 
collected several times, not only in the White Mountains but at 
Pecos (Standley 5149), a locality not far distant from Santa Fe. 
Fendler visited Pecos at least twice and it may be that he collected 
the type of A. bracteosus there. 
In a recent treatment of the genus Amaranthus, Dr. Thellung* 
has confused this with A. pubescens (Uline & Bray) Rydb., adopt- 
ing the name viscidulus and citing pubescens as a synonym. His 
description applies wholly to the latter species. Amaranthus
