BOTANY. 
peduncles about equaling the leaves ; racemes usually very short and few- 
flowered ; flowers small, deep blue ; calyx often bracteolate, upper lip very 
short, truncate, obsoletely toothed, membranous, lower lip entire or obscurely 
toothed ; keel slightly exceeding the wings ; pods 2-3-seeded ; seed about 
1" in diameter. — Near L. pusillus ; distinguished especially by the characters 
of the calyx. In the valleys and lower canons of Western Nevada to the East 
Humboldt Mountains, (more frequent than the last,) and on the islands of 
Salt Lake ; 5-8,000 feet altitude ; May- July. Also collected by Dr. Ander- 
son (84) near Carson City. Plate VII. Fig, 1. A plant ; full size. Fig. 2. 
A flower. Fig. 3. The petals. Fig. 4. The stamineal column ; all enlarged 
two diameters. (222.) A form of this was collected with some of the pe- 
duncles much elongated and bearing above the leaves loose racemes of 
reduced florets, apj^arently perfect in all their parts, but usually sterile.

LupiNUS UNCiALis. Annual, dwarf, villous, difiusely branched, leafy; 
leaflets 5, oblong-spatulate, obtuse; flowers small, axillary, solitary; the pedun- 
cles equaling the leaves or shorter ; legumes 2-seeded. — Very small, but 1' 
high ; leaves on J-J' petioles, leaflets 2" long ; stipules adnate, obtuse ; bracts 
short, oval ; the upper lip of the calyx deeply 2-clcft, the lower larger, 
3-toothed, the middle tooth small ; vexillum obovate, shorter than the wings

l^eel rather obtuse ; flowers ochrolcucous, the keel tipped with purple. Found 
on the dry foot-hills of the Truckee and Pah-Ute Ranges, Western Nevada ; 
5,000 feet altitude; May, June. Plate VII. Fig. 5. An entire plant; 
twice the natural size. Fig. 6. A flower. Fig. 7. Calyx, opened out.

LuPiNUS PARViFLORUS, Nutt. Ercct, branching, glabrous or somewhat 
hirsute-pubescent ; leaflets 5-9, oblong-obovate, obtuse or acute, longer than 
the petiole; racemes elongated; flowers small, somewhat scattered; calyx silky- 
pubescent, lips nearly equal, the upper 2-toothed, the lower entire; keel 
ciliate ; legume hirsute, 2-seeded. — A well-marked species, tall, (2-4° high,) 
dark green and nearly glaljrous, the leaflets expanded and petioles 
short. Collected in the Rocky Mountains, near the sources of the Snake
