late, three to nine lines long : flowers few, in axillary naked very 

 loose heads, nearly white, two to four lines long, on slender pedicels 

 often half as long, at length reflexed : calyx very narrow, the slender 

 teeth much shorter than the corolla. — In the Sierra Nevada, from 

 the Yosemite Valley, at Clark's, to Sierra County, from several collec- 

 tors. Of the T. gracilentum group, which is otherwise confined chiefly 

 to the Coast Ranges. 



Trtfolium Palmeri. a glabrous and diffuse annual, the stems 

 ascending, about a foot high or less : stipult-s elongated, narrowly 

 acuminate ; leaflets oblong to narrowly lanceolate, acute or acutish at 

 each end, serrulate, a half to an inch long : peduncles axillary : heads 

 naked, 10-20-flowered; flowers sessile, at length reflexed : calyx three 

 lines long, deeply cleft into narrow acuminate entire lobes : petals 

 purplish, scarcely exceeding the calyx : pod 2-seeded. — Guadalupe 

 Island ; Dr. E. Palmer. 



Dalea Californica. Shrubby, with the leaves and younger 

 branches canescent with a fine appressed pubescence : glands mostly 

 obscure, but upon the peduncles sometimes prominent and prickle- 

 like : leaflets one or two pairs, linear-oblong, not two lines long, decur- 

 reut upon the short rhachis : flowers on short pedicels in a loose 

 raceme, purple, four lines long : calyx half as long, finely pubescent, 

 the ovate acute teeth shorter than the tube : ovules two. — Known as 

 yet only from scanty specimens recently collected by Dr. Parry in the 

 San Bernardino Mountains, California. It adds another to a group of 

 more or less woody or shrubby species, which may be separated as a 

 section XylodaleUj characterized by having the claws of the petals 

 adnate to the stamineal tube only at the very base, the flowers spread- 

 ing or reflexed, mostly in loose spikes or racemes, and the ovules in a 

 few of the species four or six. It includes a dozen species, some 

 with calyx very pubescent and teeth mostly slender (Z). scoparia 

 Gray; D. frutescens, Gray; D. Emoryi, Gray ; D. arborescens, Torr. ; 

 D. poIyadeniajTorr.; D. amoena, Watson), others with the calyx spar- 

 ingly pubescent and broadly toothed (D. Fremontii, Torr. ; D. Cali- 

 fornica, Watson ; D. Johnsoni, Watson ; D. Kingii, Watson ; D. 

 ScJiOttii, Torr.; and D. spinosa. Gray). The species D. argyrcea, 

 J). Parryi, and D. hucostachys are intermediate between this section 

 and the true Daleas. The genus Asagrcea of Baillon, founded on 

 D. spinosa and characterized by the several ovules and sim[)le leaves, 

 can hardly be maintained, as D. SchotUi likewise has simple leaves 

 but only two ovules, while in D. scoparia at least the ovules are 

 four.
