somewhat brown-hairy on the upper side, margined with a continuous 

 white thickene'd border which is irregularly toothed ; teeth approxi- 

 mate, broad and thick, three or four lines long, pointing upward or 

 often cleft and pointing both ways : fruit rather smaller. 



With this was found growing a third species, which from the foliage 

 appears to be the same as the palm found in San Diego county, and 

 recently introduced into cultivation under the name of '■'• Brahea Jila- 

 meittosa." Its fruit, however, is very different from that of the preced- 

 ing, much smaller, black and pulpy with a somewhat crustaceous 

 integument, the seed very small (three lines long), and the albumen 

 scarcely at all excavated. It is also peculiar in other respects. The 

 tree is spoken of as taller and much more handsome than the last. 



"^ Cypripediuii occidentale. More or less roughly and glan- 

 dular-pubescent, a foot and a half high, leafy, usually 2-flowered : 

 leaves ovate, the uppermost broadly lanceolate, acuminate : the 

 brownish narrowly lanceolate sepals and linear-lanceolate petals 

 acuminate, nearly two inches long ; lip oblong, an inch long, dull 

 white, veined with pur|)le : sterile stamen oblong-lanceolate, acute, 

 yellow dotted with purple. — C. parvijiorum, Hook. Fl. Bor.-Am. 2. 

 205, in part, and Kevv Jour. Bot. 7. 376. C. passerinum, Gray, Proc. 

 Am. Acad. 8. 403. In the mountains of California from Santa Cruz 

 and Mariposa counties northward to the Columbia River. Frequently 

 collected (Tolmie, Burke, Spalding, n. 334 Geyer, n. 513 Torrey, n; 

 513 Hall, Bolander, n. 970 Kellogg & Harford, Gray, Nevius), and 

 very similar in habit to C. parvijiorum. 



'^ Cardamine Gambellii. Perennial, glabrous throughout, erect, a 

 foot and a half high : leaflets four to six pairs, ovate-oblong to linear, 

 sessile, entire or sparingly toothed, acute, three to twelve lines long : 

 flowers white on slender pedicels : petals four lines long, twice longer 

 than the calyx : pods narrowly linear, ascending, an inch long, equal- 

 ling the strongly reflexed pedicel ; beak a line long, slender. — Col- 

 lected by Gambell near Santa Barbara, and recently by Dr. J. T. 

 Rothrock, of Lieut. G. M. AVheeler's Exploring Expedition, in the 

 same locality. Resembling C. pratensis. A very similar form, but 

 somewhat pubescent, has been found by Bourgeau near the city of 

 Mexico. 



'^ Vauquelinia Torreyi. Shrub or small tree: leaves coriaceous, 

 narrowly lanceolate, acuminate, acute at base and shortly petioled, 

 acutely serrate, white-tomentose beneath, smooth above, pinnately 

 nerved with reticulated veinlets. about an inch and a half long: flowers 

 in small terminal tomentose panicles : petals white, oblong : stamens 25^
