stipules minute, entire; involucre single, terminal (always ?) turbinate, pedicelled, with downy lobes, and transversely 
oblong glands without appendages ; styles very short ; capsule (immature) acutely 3-angled, glabrous. — South Florida, 
Curtiss. — [Second edition, 1883.] 
From Parry’s BoTANICAL OBSERVATIONS IN SOUTHERN UTAH (AMERICAN Natvurauist, Vou. IX. 1875). 
- EupHorsia Parryt,n. sp. Annual, erect, hersow pale-green, glabrous, with dichotomous spreadi ng [350] 
baa ; leaves linear, nearly equal at base, acutish or acute at both ends, with setaceously slit stipules ; invo- 
lucres sist anulate, on moderately long peduncles in ye forks of the branches, with unequal small truncate appen- 
dages ; style short, somewhat erect ; capsule sharp-angled, seeds ovate, minutely granulate. — St. George, in loose 
drifting ls Plant about a span in height ; leaves }-1 inch long, } line ate rolled cchiete when drying ; invo- 
lucres 3-1 line long, and with the hiiaiidswhiks appendages of the same width ; stamens numerous, with conspicuous 
feathery bracts between them ; styles about the length of the ovary ; seeds ? line long, rather “thick, obtusely angled, 
surface covered with minute granules, disposed in transverse lines. Habit very similar to Z&. revoluta, Engelm., but that 
has a dark purplish-green color, revolute not involute leaves, very much eae slender turbinate involucres 
on pat peduncles, and suites sharp-angled, strongly cross-ribbed seeds. The characters of our species point [351] 
an alliance with Z. zygophylloides, Boiss.
