226 PITTONIA. 



oles, rouiul-ovate to deltoid and broadly rlioinboid, lepaud- 

 toothed or entire, only 3 to 5 lines long: cauline narrowly 

 elliptical to linear-lanceolate, eiitire: stems simple and almost 

 scapiforra or sparingly branched: flowers minute, yellow; 

 sepals snbscarious, not reflexed; petal mostly 1 only; stamens 

 very few: aclienes rather numerous in a small globose liead, 

 little compressed, delicately tuberculate on the sides, neither 

 margined nor beaked, scarcely ^ line long; stigma minute 

 and sessile. 



In moist land, on the plains of Sonoma Co., California, 

 May 1, 1892, Mr. F, T. Bioletti; a peculiar and very dwarf 

 species, somewhat resembling the Chilian plant figured in the 

 Botany of Beechey^s Voyage ( t. 2), nndor the name of R- 

 hitmilis; but that has a ditferent foliage and an achene beatei^l 



by a manifest style. In ours the ovary (and achene) is 

 marked by a green crest-like elevation of the whole uppf^r 

 part, in the midst of which the depressed stigrnatic organ 

 may be detected only by the help of a lens. 



BoLELiA. HUMins. Yery dwarf, the rather stoutish stem 

 only about an inch high, the linear ovaries and capsules quite 

 as long: segment of the calyx linear, acutish, unequal, a Hue 

 or two in length: corolla minute, white, scarcely a line long, 

 bilabiate, but the segments of npper and lower lips not very 

 dissimilar, all ovate-oblong and acute. 



Moist plains, in Sonoma Co., along with Ranunculus Bto- 

 letii, and by the same collector. The species is a most remarlc- 

 able cue on accouut of the insignifictintlj small and white 

 corolla, reminding one again of the genus HotcclUa. 



Erigeron lei'tophyllus. Near E. CouUeri, hat rather 

 taller, 10 to 18 inciies high, leafy mostly at or near tlie base, 

 the cauline foliage reduced and inconspicuous: pubescence 

 short and spreading, stiffish, most abundant on the involucre 

 which is neither glandular nor viscid: radical and louver 

 cauline leaves 3 to 5 inches long, narrowly oblaneeolate, 

 obtuse, mucronulate, entire or with a few remote serrate
