6cm. in diameter, 5-partecl into broad cuneate segments, these 

 unequally 3-5-lobed, shortly mucronate, sparsely short liairly on 

 both faces ; the long petioles broadened below into a somewhat' 

 sheathing, ciliate base ; flowers pale yellow, pubescent, 3cm. 

 long, half of that length occupied by the stout, straight or only 

 slightly curved horizontal spur; the divisions broadly obvate, 

 regular, the mouth about 2cm. across. 



No. 5256, collected on grassy slopes about rocks, near 

 Bodega Bay, along the road leading to the village of Bodega. 

 A well-marke^' species, its nearest relative being D. nudicaule. 



^CRATAEGUS GAYLUSSACIA, sp. nov. 



A slender tree about 20 feet high, with gray bark, the 

 young twigs reddish; branches slender, rather remote, wide 

 spreading; thorns stont, scattered, 1cm. long; leaves pubescent 

 above, with short appressed hairs, especially on the veins, 

 especially on the veins, glabrous or nearly so beneath, those on 

 the young shoots broadly ovate, about 4cm. long, 3cm. wide, 

 acuminately tipped, irregularly serrate and somewhat three- 

 lobed, the teeth callous tipped; the leaves of the older growth 

 obovate, cuneate, 3-4 cm. long, including the slender petiole of, 

 5mm., irregularly serrate, the teeth sharper and closer than on 

 the leaves of the young shoots, the end commonly broad, but oc- 

 casionally pointed ; fruit purple-black, small, about 4mm. in di- 

 ameter, surmounted by the five short, obtuse calyx lobes ; in size 

 and general appearance much resembling the common black 

 huckleberry of the East, whence the specific name. 



No. 6052, in fruit only, collected in thickets in low ground 

 along the Lagoon at Sebastopol, Sonoma county, August 20, 

 1902. Heretofore this distinct species has passed for C. 

 rivularies, Nutt., collected originally by Nuttall in the Rocky 

 Mountains of Montana, the type of which is preserved in the 

 herbarium of Columbia University, New York City, and is quite 

 different from our California plant. 



MENTZELIA PINETORUM, sp. nov. 



Annual; 4-6dm. high, pale and somewhat shining, 

 especially below; pubescent with short hairs; branched from 

 the base, the branches ascending, rather weak; lower leaves 

 oblong, with a maximum length of about 8cm., 1cm. wide, 

 shallowly sinuate, narrowed below to a clasping base, usually 

 blunt, the upper successively shorter and somewhat broader, 

 becoming sessile, the ones contiguous to the inflorescence ovate 

 and half as broad as long, acute ; calyx only 1mm. long, the lobes
