102 PROCEEDINGS OF THE CALIFORNIA 



cate, turgid. The fruit and seed are known only from Fremont's specimens 

 communicated to Dr. Torrey (No. 284 of Coll. 1846,) from California, a taller 

 and less diffuse form than that now collected by Prof. Brewer, and more like 

 Nuttall's, from Tatnall County, Georgia. But my original specimen of the latter 

 little-known plant is too incomplete to make certain the identity ; and the two 

 are widely sundered in geographical station. Still no adequate characters yet 

 appear to distinguish specifically. Prof. Brewer collected his plant April 18th, 

 in the valleys among high ridges in Sonoma, where it abounded. 



Calandrinia H. B. & K. 

 C. Menziesii, Hook. 

 In various forms in southern California. Capsule slightly if at all exceeding 

 the calyx ; seeds rather turgid, shining ; petals mostly much exceeding the calyx. 



C. Menziesii, var. macrocarpa. 



Stems and racemes at length more elongated and loosely-leaved ; pedicels in 

 fruit much spreading or recurved ; capsule ovoid-fusiform, projecting beyond 

 the calyx ; seeds smaller, compressed and opaque. 



Dry hills of the Santa Inez mountains, near Santa Barbara. 



Perhaps a distinct species, but I want to see it confirmed by other specimens. 



LlNUM L. 



L. Breweri, n. sp. 



Annual ; glabrous ; stem very small, not striate, with few flowers crowded at 

 the apex ; leaves filiform, smooth, alternate and opposite ; stipules conspicuously 

 glandular ; pedicels shorter than the calyx ; sepals oblong-ovate, acute, one- 

 nerved, margin not scarious, glandular, less than half as long as the bright 

 yellow, obovate-oblong petals ; anthers elongated-oblong ; sterile filaments almost 

 wanting ; styles three, distinct ; stigma somewhat acutely pointed. 



Dry hill sides of the Diablo Range, near Marsh's Ranch, May 29th. 



Plant barely two to three inches high, " but seen in the valley larger, with 

 many flowers, not yet expanded." 



This, like L. Cahfornicum, appears to be uniformly tri-carpellary ; flowers 

 about the size of those of that species, and the anthers elongated-oblong ; but 

 the leaves narrower ; the stigmas not at all capitate or enlarged, but minute 

 and acute ; fruit not seen. 



Trifolium, L. 



T. bifidum, n. sp. 



Somewhat villose or glabrous ; stems from small (annual ?) root, slender, 

 spreading ; stipules ovate-lanceolate, setaceously-acuminate, entire ; leaflets 

 linear-cuneate, lateral ones rarely dentate, bifid or incised at the apex with a 

 mucronate point between the lobes ; peduncles twice or three times as long as 

 the leaves ; heads naked, six to twelve flowered, or more ; flowers pedicelled, at 

 length reflexed ; calyx five-parted, dentate, subulate-setaceous, somewhat hirsute, 

 and nearly equal to the persistent, rose-colored scarious corolla. 



Near Marsh's Ranch, between Monte Diablo and the San Joaquin, among 

 grass in a ravine near the water, May 29th.
