122. MADIA, Molina. 



M. Yosemitana, PARRY, p. 304. Add syu. : M. Rammii, Greene, Bull. Calif. Acad. i. 90, 

 the larger and fully developed form, sometimes 18 iuches high (occurring aloug the western 

 base of the Sierra Nevada), the original of Parry being the most depauperate. 



124. HEMIZ6NIA, DC. 



H. citriodora, GRAY, p. 307. Add to syn. : Madia citriodora, Greene, Bull. Torr. Club, Ix. 

 63, & Bull. Calif. Acad. i. 91. To habitat add : Hood River, Oregon, Mrs. Barrett, Klickitat 

 Co., Washington Terr., Suksdorf. Instead of the statement about Madia anomala, add : 



H. anomala. More hirsute and viscid than the preceding, destitute of soft villous pubes- 

 cence, not at all lemon-scented : rays "3 to 5, greenish-yellow" : bracts of receptacle uncon- 

 nected : akenes of disk and ray similar, larger than in related species (2 lines lung), turgid 

 oval, obscurely gibbous, subterete, very obtuse or retuse at both ends, wholly destitute of 

 terminal apiculatiou and of basal stipe or callus, not at all angled, or in ray-akenes a very 

 obscure ventral ridge. Madia anoi/ui/a, Greene, Bull. Calif. Acad. i. 91. California, on 

 hills and mountains in El Dorado and Lake Co., Mrs. Lai/ne-Cnrran. The akeues confirm 

 the reference of the preceding species with the present one to Euhemizonia. 



H. Streets!!, GRAY, mentioned on p. 307, to be introduced on p. 308, before H. cori/mlioan. 

 Erect or ascending, at length much branched, 5 to 15 inches high, more or less hirsute, desti- 

 tute of (/lands, usually very leafy up to the numerous corymbosely crowded heads : leaves 

 linear, obtuse, short (the larger only inch and a half long), entire or with a few coarse short 

 teeth: heads 3 or 4 lines high : involucral bracts short and linear; those of the receptacle 

 15 or more in a circle, slightly united below : rays 14 to 20 : disk-flowers numerous : akenes 

 of the ray rugose-tuberculate at maturity, indistinctly triangular, with a prominent upturned 

 beak; those of the disk sterile, bearing a pappus of about 10 subulate-linear palete of half 

 the length of the corolla. Proc. Am. Acad. xii. 162, from dwarf or early specimens. 

 Islands of California, Santa Catalina, Li/on, San Clemeiite, Nevin & Li/on. (Lower California 

 on San Benito Island, Dr. Streets.) 



127. LAYIA, Hook. & Am. 



L. heterotridia, HOOK. & ARN., p. 315. Pubescence all short and fine; hispid or hirsute 

 hairs none or few in the original specimens, but moderately developed in a form which is 

 distinguished from L. glandulosa, chiefly by the want of crisped wool to the pappus. 



Var. major. Robust, the copious pubescence all short : heads and rays large : pappus 

 more or less deciduous from the disk-akenes in a ring at maturity (which the original of the 

 species also shows). L. graveolens, Greene, Bull. Calif. Acad. i. 92. California ; near An- 

 tioch, Kflhyrj, and Tehachapi Pass, Mrs. Layne-Ciirran. 



137 1 . CROCKERIA, Greene. Next to Eatonella, p. 323. (Dedicated 

 by the discoverer to Charles Crocker, Esq., of San Francisco, one of the most 

 liberal promoters of botanical exploration in California and adjacent regions.) 

 Habit, involucre, flowers, and receptacle essentially of Lasthenia Hologymne. 

 Akenes oval-obovate, very flat and the plane sides nerveless, glabrous ; margins 

 with a distinct filiform nerve, and very densely ciliate with short and pyriform or 

 clavate rather rigid more or less glandular hairs ; apex truncate. Pappus none. 



C. chrysantha, GREENE, Bull. Calif. Acad. i. 93. A span or two high from a slender 

 annual root, nearly glabrous, not at all woolly : leaves all opposite, linear, entire : heads a 

 quarter-inch high: involucre nearly hemispherical, shorter than the disk ; the 12 to 14 ovate 

 bracts cupulate-connate to the middle : rays and numerous disk-flowers golden yellow, and 

 quite like those of Lasthenia glabrata. To refer the plant to that genus seems impractica- 

 ble. Valley of the San Joaquin, California, in alkaline soil near Lake Tulare, April 15, 

 1884, E. L. Greene.
