California, Zobé 270, cultivated at Berkeley, Greene, 1892; 
cultivated at Reno, rgro, from Elmira seed, Kennedy. 
Cultivated in the field in this climate the leaves become 
much smaller, as would be expected on account of the dry at- 
mosphere.

T. californicum forma turbinatum (Jepson) McDermott 
A much branched annual about a foot high, more or less 
villous pubescent throughout, with elongated heads and showy, 
conspicuous flowers. Corolla deep purple, tipped with cream. 
Annual, stems numerous from the base rather slender, di-

to elliptic-oblanceolate, dentate, about 1 cm. long, petioles 2 to 
5 cm. long; upper leaflets larger, about 1.5cm. long, narrower 
and with shorter petioles; stipules small, lobes broadly ovate,
