Eastwood : Californian Species of Delphinium 669 



II. NEW SPECIES OF DELPHINIUM 



• 



Delphinium polycladon sp. nov. 



Stems 8 dm. tall with many spreading, slender, rather weak 

 branches. Lower part of plant glabrous, pubescence scanty on 

 the leaves, denser on the upper stems and pedicels, close on the 

 follicles. Leaves mostly near the base, orbicular in outline, 6 cm. 

 across, with 3-5 broad, cuneate divisions having short, acuminate 

 lobes : petioles long and slender, often more than 10 cm., dilated 

 at the clasping base. Inflorescence paniculate, pedicels erect, 2-4 

 cm. long, bracts narrowly subulate, bractlets filiform near the 

 flower. Flowers small, about 2 cm. across, bluish purple. Sepals 

 obovate, obtuse, spur 8 mm. long, usually curved at tip. Upper 

 petals white veined with blue, lower petals oblong, deeply emar- 

 ginate, with a prominent spur on the claw and a yellowish, very 

 hairy spot at the base of the blade. Follicles with thin walls 

 through which the outlines of the large seeds are plainly visible, 

 becoming almost moniliform when the seeds are ripe, spreading 

 but little. Ripe seeds brown, angled, rugose, almost 2 mm. in 

 diameter. 



This interesting Delphinium was collected by the writer near 

 the forks of Bubbs Creek in Fresno county, California. It grew 

 in a thicket where the ground was springy. It was impossible with 

 the tools at my command and the time at my disposal to dig up 

 the roots. It was collected July 9, 1899. 



* Delphinium pratense sp. nov. 



Root grumous, small and near the surface. Stems slender, 

 simple or branched from the base, about 3 dm. high. Pubescence 

 villous with soft, white, deflexed-spreading hairs, usually densest 

 on the lower stem and inflorescence. Radical and lower cauline 

 leaves about 3 cm. broad, with 3-4 cuneate divisions each with 

 linear-oblong mucronate lobes : petioles 3-6 cm. long, broadening 

 at base and sheathing the stem : cauline leaves, except the lowest, 

 really bracts subtending the lowest pedicels, with simple, linear, 

 entire divisions or lobed. Flowers at first scattered on long pedicels, 

 later forming a loosely or closely flowered raceme which is simple 

 or compound : lower pedicels 5 cm. long, upper 1.5 cm. : upper 

 bracts becoming simple and linear, about half as long as the 

 pedicels : bractlets opposite or alternate, on the upper part of the 

 pedicel, narrowly linear. Flowers purple and white, small, 1 5 

 mm. across, the spur straight, horizontal, 1 cm. long, very
