PLANTS HITHERTO UNDESCRIBED. 117 
Gravelly slopes and hills of Alameda Co. and southwards 
in California; common. Type Prof. Brewer’s No. 512 col- 
lected on the Geological Survey of California, 1862, and 
preserved in the herbarium of the University of California, 
At once distinguished from S. eurycephalus with which it has 
been confused, by the more numerous heads and corymbose 
inflorescence, the cut and apparent glabrousness of the 
foliage, and the broad involucral bracts. The leaves of 
S. eurycephalus bear remnants of tomentum even when the 
plant is fruiting: the involucral bracts are about 20 in 
number, narrow, with a thick fleshy midrib leaving a narrow 
sub-scarious margin; in flower they cohere somewhat, 
separating irregularly in fruit. The range of the latter 
plant is more northerly than that of S. Breweri and it appears 
to prefer the neighborhood of streams. 
Senecio caulanthifolius. Stems 2 or 3 from a perennial 
rootstock, erect, simple, about 2 ft. high, clothed when 
young with very short sparse wool: radical leaves with long 
slender petioles, narrowly cuneate-ovate obtuse, to lanceolate- 
elliptical acutish, coarsely and doubly crenate-serrate, roughish 
above with minute scurf; veinlets reticulate, flexuous: 
lower cauline leaves long-petioled, pinnatifid; upper smaller 
and more distant, sessile, semiamplexicaul, laciniate: inflor- 
escence loosely corymbose; heads several; pedicels long; 
involucres 4 lines high, bracts about 15, broad, 2-ribbed, 
scarious margined, with few bracteoles, these about 4 their 
length; rays broad. 
Murphy’s Camp, Calaveras Co., Calif., May 24th, 1895; my 
No. 1437. Type specimens in the herbaria of the University 
of California and of Professor Greene. Readily distinguish- 
able from S. Breweri by the foliage and much longer pedicels. 
Triglochin concinna. Rootstock perennial, stoloni- 
ferous: leaves 4 or 5, 4-6 in. long, usually less than 1 line 
wide, linear, half-terete, flattened and slightly grooved on the 
inside, flattened on both sides at the apex: scape slender, 
wiry 8-13 in. high sometimes attaining 17 in., not densely
