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, i 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 2^ 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 Y-z 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 3'^ellow sepals are rather conspicuous. It is not 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 Stanleya collina. 



Lepidium heterophyllum. I propose this name for the L. 

 tnontanum var. alpium, Watson, King's Rep. and L. integrifoliiim 

 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 L. montaiimn or the alkali-loving 

 L. integrifoliuni of the valleys. It reaches an altitude of nearly 

 9,000 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, 

 I 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
