stem leaves rapidly reduced upwards, sessile, apparently (but not) 
clasping, uppermost ovate to sagittate, or hastate, acuminate, the 
rounded or almost acute lobes 3 to 4 lines long, petioles of root leaves 
grooved; spikes sessile and in the fully developed plants many 
branched; the central branch long, 1 to 2 feet, densely flowered; 
sepals in the bud greenish yellow, after anthesis purple (usually) and 
reflexed, linear-oblanceolate, obtuse, concave, almost hooded; blade 
of petals crumpled crosswise, edges jagged, linear, % line wide, yel- 
lowish green, inconspicuous, 4 to 6 lines long, and thin, claw thick, 
fleshy, triangular subulate, 6 lines long and a line wide at the sac- 
cate base, glabrous, whole petal just equaling the filiform filament, 
which is round, glabrous, and scarcely enlarged at base, anther 
loosely coiled 21% lines long, obtuse, narrowly linear, fixed by the 
very base and one-sided; pedicels in flower 2 lines long ascending 
- and in fruit 4 lines long and horizontal; pods drooping, 2 to 3 inches 
long, stipe 8 to 10 lines long, septum less than ¥% line wide. It grows 
among pinons and cedars on gravelly southern slopes of hills at 
6,500 to 7,000 feet altitude in the Schell Creek and Sprucemont 
Ranges, Nevada, and flowers about July 15 to August 15. The 
greenish yellow sepals are rather conspicuous. Itisnot very common. 
It differs from the type so far as the descriptions go in the winged 
stems, branching habit, crumpled petals, auricled or hastate upper 
leaves, and longer pendent pods. But it may be that these charac- 
ters were overlooked in the type. Should this plant prove to be dis- 
tinct it may bear the name of Sfan/eya collina. 
LEPIDIUM HETEROPHYLLUM. I propose this name for the Z. 
montanum var. alpium, Watson, King’s Rep. and ZL. integrifolium 
var. heterophyllum, Wat. Am. Nat., Ix, 268. I fail to see anything 
warranting the connection of this shrubby based, cliff-growing, de- 
cumbent, high altitude plant with ZL. montanum or the alkali-loving 
L. integrifolium of the valleys. It reaches an altitude of nearly 
g,000 feet in the Wasatch and shows no gradation into either species 
either in habitat or character so far as I know. 
POLYGALA ACANTHOCLADA Gray. It may be of interest to give 
the characters of the flowers of this plant as they are in nature and 
not in dried specimens: Green parts of calyx 3, ovate, barely acute, 
1 line long, the two upper (this is as the flower appears on the plant 
with the keel uppermost) close together, lower one alone, the two
