PARSLEY FAMILY 659 



6. E. minimum C. & R. Mountain Eryngo. Low, depressed-tufted, the stems 

 several to many, nearly simple, thickened toward the base and markedly retro- 

 curved, 1 to 4 inches long ; leaves mostly basal, 2 to 6 inches long, the blades merely 

 cleft and toothed to piunately divided with cleft or toothed ovatish segments, the 

 segments i^ to 1% inches long, the teeth and petioles more or less spinose ; heads 

 subsessile or on very short peduncles, nearly globose, 21^ to 3^ lines high ; bracts 

 broadly lanceolate, equaling or slightly exceeding the heads, the lower % with 

 spinose bristles ; bractlets broadly linear-lanceolate, a little longer than the flowers, 

 with a conspicuous scarious margin below, at the top of which and just above are 

 a few bristles; sepals scarious-margined; styles exceeding the sepals.

 Plumas Co. North to eastern Oregon. July- Aug.

7. E. aristulatum Jepson. Ground Eryngo. Stems prostrate or low-diffuse, 

 very slender, 10 to 15 inches long ; basal leaves tapering into a long petiole, 4 inches 

 long (including the petiole) , the short blade spinose-toothed and with a few lanceo- 

 late segments ; cauline leaves opposite, sessile, spinulose-serrate ; heads very numer- 

 ous, 21/2 to 3I/2 lines long; bracts exceeding the head, about 41/0 lines long, densely 

 spinescent at base ; bractlets spinose, the body narrowly lanceolate, inversely sagit- 

 tate-winged from the base upward, the lobes of the wings thus forming sinuses, in 

 each of which are borne 1 to 3 awns surpassing the breadth of the wing; sepals 

 hyaline-margined, exceeded by the long styles. 



Dry summer flats, wet in winter, 1400 to 3000 feet : Lake Co. July. 



Locs. — Mt. Konocti (Uncle Sam Mt.) ; Boggs Lake, Bottle Glass Mt., K. Brandegee ; Scotts 

 Valley, Tracy 2375 (stems somewhat retrocurved, apparently not prostrate, bracts much longer

8. E. racemosum Jepson sp. n. Stems slender, decumbent or prostrate, 2 or 

 3 from the base, 9 to 13 inches long ; phyllodes slender, the later ones tipped with 

 nearly entire or merely spinulose-margined blades % to l^o inches long; cauline 

 leaves mostly bracteal, the blades oblong to lanceolate or oblanceolate, Y2 to 1 inch 

 long, the lower petioled, the upper mostly sessile ; cymes for the most part only once 

 branched, the branches much elongated, bearing racemosely the small short-pe- 

 duncled heads ; peduncles 2 to 3 lines long ; heads 2 to 3 lines high ; bracts and 

 bractlets little unequal, surpassing the flowers ; bracts spinulose at base, bractlets 

 scarious-margined at base, not spinulose. — (Caules graciles prostrati unc. 9-13 

 longi ; phyllodia gracilia ; folia caulina plerumque bracteata ; cymae monoramosae, 

 ramis elongatis capitulis parvis racemosis ; pedunculi lin. 2-3 longi ; capitula lin. 

 2-3 alta.)

 Locs. — Lathrop, Bioletti; San Joaquin City, Jepson 10,287 (type). 



9. E. jepsonii C. & R. Button Eryngo. Stems slender, erect, freely branch- 

 ing, 1V4 to 1% feet high ; leaves oblanceolate, often very narrow, spinulose, some- 

 times incised, the lower narrowed at base to a slender spinulose petiole, the upper 

 short-petioled or sessile ; heads 3 to SYo lines high, much surpassed by the bracts ; 

 bracts rigid, 4 to 8 lines long, with few short bristles at base ; bractlets lanceolate, 

 all or nearly all shorter than the flowers, not spinulose, the scarious margin at base 

 broadening upwards; sepals exceeded by the long styles.
