sandy locations near the southern shore. It is generally 

 an annual, but in some favorable situations persists and 

 becomes perennial. 



683. Trifolium microcephalum Pursh. — Abundant 

 in the field of the Sierra de la Laguna. 



127. Dalea trochilina. — Woody, 1-1% m. high, 

 branched above, glabrous: leaflets 7-15, obovate, 3-5 mm. 

 long, thickly beset below with glands: spikes dense, 2-4 

 cm. long: bracts firm in texture, broad, narrowed to the 

 base and somewhat abruptly lanceolate-pointed, white 

 silky-pubescent, especially near their edges : calyx ribbed, 

 white silky-pubescent, with deltoid lanceolate teeth shorter 

 than the tube : corolla pink, conspicuous, the petals nearly 

 equal in length, the banner round-deltoid in shape: sta- 

 mens 10: ovary pubescent, 2-3-ovuled. 



This species is common about La Chuparosa and pecu- 

 liar to the summits of the high mountains of the Cape 

 Region, where it is a conspicuous plant of the flora. It 

 often becomes 3-4 feet high, and the ends of the branches 

 bear an abundance of bright pink showy flowers. Its 

 habit is to send up from the root a few, sometimes onl}^ 

 two or three, woody stems that are naked below and much 

 branched above ; and as the stalks are only about half an 

 inch in diameter, they are bent by the weight of the top. 

 Herbarium specimens ver}^ much resemble D. ramosissinia 

 Benth.jfrom Magdalena Island, but are easily distinguished 

 by the very different and less deciduous bracts of the 

 flowers, by the broader and less acuminate calyx teeth, 

 and by the obovate and not cuneate leaves, inclined some- 

 times to be apiculate rather than retuse. D. ramosissinia, 

 with which this species was confounded in Proc. Cal. 

 Acad., Ser. 2, Vol. iii, 126, is a low woody plant, form- 

 ing dense tufts hardly more than a foot in height. 



129. Dalea Parryi T. & G. — A large form abund- 

 ant about San Jose del Cabo.
