STANDLEY—-ALLIONIACEAE OF THE UNITED STATES. 329 
4, Tripterocalyx cyclopterus (A. Gray) Standley. 
Abronia cycloptera A. Gray, Am. Journ. Sci, If. 15: 319, 1853, excluding 
synonyms, 
Abronia carnea Greene, Pittonia 3: 343, 1898, 
This name might very properly be reduced to synonymy if it were not for the 
fact that certain excuses can be offered for it. Doctor G ‘ay evidently intended 
it merely as a new name for Abronia micrantha because he considered the latter 
naine inapplicable to specimens he had examined which were really not A. 
micrantha at all, but a southwestern plant which resembles it somewhat. From 
what he says at the time he proposed the name it can be definitely stated that 
he had in mind the specimens collected by Wright in western Texas and not 
the northern plant to which the name micrantha was originally applied. The 
name will be considered a nomen nudum by some, or a mere synonym of 7. 
micranthus, but the present author believes that long-established usage makes 
it allowable and preferable to retain it. 
Abronia carnea is certainly a synonym of 7, cyclopterus; the types of the two 
came from localities separated by not more than 40 miles. The plant is not a 
perennial, as Doctor Greene surmises in his description, but an annual which 
blooms from early in the spring until late in the summer.

5, Tripterocalyx wootonii Standley, sp. noy. 
Annual: stems ascending. 25 em. high, with scattered rough pubescence 
throughout, finer than that of 7. cyclopterus; leaf blades rather broadly lanceo- 
late, 80 or 40 mm. long and 10 to 15 mm. wide, the margins sometimes slightly 
undulate, ciliolate; blades with rather abundant chaffy pubescence beneath and 
frequently above, acute or rarely rather obtuse, narrowed at the base into a 
petiole as long as the blade or shorter: peduncle 6 cin. long, with rather abun- 
dant viscid pubescence; bracts 11 to 15 mm. long and 2 mm. wide, narrowly 
lanceolate, long-acuminate; flowers 25 to 30 mm. long, whitish or very pale 
pink, tube densely glandular-pubescent, limb 9 mm. broad: fruit 15 to 20 mm. 
long and almost as broad, hispidulous especially on the ribs and along the mar- 
gins of the wings: wings not as much narrowed below as those of 7. cyclopterus, 
rounded above, finely reticulate-veined, the body with usually 3 strong ribs be- 
tween each pair of wings; seed 5 mm. long. 
Most of the material from northwestern New Mexico and northeastern 
Arizona which has passed as 7’. cyclopterus is to be placed here. This species 
is distinguished from that by its considerably smaller, hispidulous fruit (the 
fruit of some of the northern plants is much smaller than that of the type), 
narrower bracts, more pubescent stems and peduncles. and pale flowers, and 
by its lower, less erect habit: the leaves when fresh have a peculiar glaucous 
appearance different from leaves of 7. cyclopterus, The differences in general 
appearance between the two species are less apparent in dried than in living 
material. Type in the herbarium of the New Mexico Agricultural College, con-
