glands with narrow or with longer, sometimes triangular, entire or dentate 
or lobed, greenish or reddish appendages, or without any ; seeds quadran- 
gular-oblong, undulate and scrobiculate—Santa Fé, Rothrock (13), 1874; 
number 1003 is the same from Arizona. Not rare from Western Texas, 
through New Mexico and Southern Colorado to Arizona. A diminutive, 
suberect bush of many stems and branches, very variable in the width of 
its leaves, but readily recognized by the characters enumerated. 
Evupnorsia (ANISOPHYLLUM) PoLycaRPA, Benth. Bot. Sulph. 50; Bot. 
Mex. Bound. 186; Boiss. J. c. 44—A perennial, often flowering in the first | 
year as an annual, prostrate or erectish, glabrous, sometimes pubescent 
(or even tomentose in a variety), with orbicular-cordate or oblong entire 
leaves, always with linear, delicately ciliate stipules; involucres axillary, 
rarely crowded into few-flowered cymes; appendages of the dark red (or, 
when dry, black) glands large and conspicuous, or smaller; seeds gray- 
reddish, linear-oblong, quadrangular, smooth or slightly undulate. The 
typical, large-flowered, glabrous form is found principally along the Pacific 
coast from Cape St. Lucas to the southern part of the State of California ; 
inland, and especially in the California Desert and up the Gila, where Dr. 
Rothrock collected it in 1874, a larger, wide-spreading, very much ramified 
form is found, with smaller, glabrous or pubescent, oblong or oblong-linear 
leaves $-14” long, with smaller involucres, very small, almost or entirely 
inappendiculate glands, and very short styles, but seeds of the same size 
and form as in the type. The stipules of all forms are alike, linear, entire, 
minutely ciliate. E. micromera, Boiss. 1. c. 44, seems identical with this 
last form, and we will have to consider E. melanadenia, Torr. Pacif. R. R. 
Rep. 4, 135, as a tomentose variety, as suggested by S. Watson; an inter- 
’ mediate form is E. cinerascens, Engelm. Bot. Mex. Bound. 186. 
Evurnorsia (ANISOPHYLLUM) SERPYLLIFOLIA, Pers. Ench. 2, 14; Boiss. 
l.c. 43; Gray, Man. 432; E. inequilatera, Engelm. Bot. Mex. Bound. 187; 
not Sonder.—Zuni, Rothrock, 1874 (173). Anextremely variable species, 
but readily recognized by its glabrous, obovate leaves, acute at the unequal 
base, broader and serrulate at the rounded tip; stipules setaceously divided. 
involucres in lateral leafy clusters; seeds gray, linear, acutely 4-angled, 
slightly wrinkled or pitted. The closely allied Z. glyptosperma, Engelm.,
