5. Aulospermum panamintense ©. & It. 
Cymopterus panamintensis C, & R. Contr. Nat. Herb. 4: 116. 1893. 
Caudex stout, branching, clothed with an abundance of old leaf 
sheaths; flowering scape 7.5 to 10 cm. high, glabrous and purplish; 
leaves finely dissected, ternate, then once or twice pinnate; ultimate 
segments tipped with a slender bristle-like apiculation; involucre 
none; involucels small, gamophyllous, somewhat one-sided, purplish, 
cleft into ovate acuminate segments; rays (in flower) about 12 mm. 
long; pedicels short; flowers greenish-yellow; fruit 10 mm. long, 
glabrous, each carpel with 5 broad wings very thick at insertion; 
oil tubes 3 or 4 in the intervals, 4 on the commissural side; seed face 
deeply concave. 
Type locality, ‘‘near Pete’s garden, in Johnson Canyon, Panamint 
Mountains, California;” collected by Covrlle, no. 508, March 30, 1891, 
type in U. 8S. Nat. Herb. 
Southern California. 
Specimens examined: 
CALIFoRNIA: Panamint Mountains, Covil/e 508, in 1891; Argus Mountains, Coville 
& Funston 739, in 1891; Argus Mountains, Purpus 5393, in 1897, 
As defined here the species is quite variable in its fruit. Coville’s Panamint 
Mountains specimen is the type, with wings very thick at insertion, and hardly 
flattened seed with deeply concave face. The two other specimens referred here 
(Coville & Funston 739 and Purpus 5393) have the same seed section, but the wings 
are not so thickened at insertion, if at all. The material in hand, however, does not 
permit us to separate them, The following form seems to be worthy of separation as 
a variety, and is fairly intermediate in character between this genus and Phellopterus. 
Aulospermum panamintense acutifolium C. & R., var. nov. 
Leaves more open, with longer segments; fruit smaller, with wings 
not thickened at insertion; seed face variable, the concavity from 
broad and shallow to narrow and deep. 
Type locality, Newberrys Springs, Mojave Desert, southern Call- 
fornia; collected by Jr. and Mrs. J. G. Lemmon, May, 1884, and 
distributed as Cymopterus terchinthinus; type specimen in U. 8.
