258 DESCRIPTION OF NEW SPECIES 



*GITHOPSIS. 



Calyx five-cleft, the segments long and linear, about the length of the adnate, 

 obconic, cylindric tube. Corolla cylindric-campanulate, deeply five-cleft. 

 Stamens five, free, filaments smooth, very short, not dilated. Stigmas three, 

 revolute. Capsule three-celled, obconic, cylindric, striated, opening within the 

 calyx by terminal pores. Seeds acute, ovate, subtriangular. An annual of 

 Oregon. Stems branching from the base, dichotomous; flowers solitary, 

 terminal and lateral, opposite the leaves, small and blue, scarcely exserted 

 beyond the long, leafy lobes of the calyx. Leaves alternate, sessile, serrated, 

 below very small. (Named in allusion to the resemblance of the flowers with 

 those of Githago segetum.) 



GiTHOPSis * Specula7'ioides. 



Hab. Plains of the Oregon, near the outlet of the Wahlamet; common. Flowering in May 

 and June, four to ten inches high, more or less branched from the base; above dichotomal, with 

 the upper part of the plant smooth. The flowers terminal or lateral, solitary: a branch usually 

 issues, from the same axill with the lower flowers, producing a sort of irregular straggling cyme. 

 Leaves oblong, or oblong-ovate, sharply serrate, the lower ones minute, the upper from a quarter 

 to half an inch long, one to two lines wide. Adnate tube of the calyx about one-third of an inch 

 long with ten striae, attenuated below into a thick pedicel; the leaf-like, linear, and sometimes serru- 

 lated segments, about the same length. Corolla tubular-campanulate, scarcely longer than the calyx, 

 border rather deeply five-cleft, the segments acute, deep blue, the base whitish. Stamens included, 

 with long linear anthers, and very short, slender, equal filaments. Stigma trifid, short and revolute. 

 Capsule three-celled, opening at the summit within the calyx, by the shrinking of the base of the 

 corolla. Seeds numerous and minute, subtriangular, even and brown. Allied to Specularia, but 

 with a cylindric capsule, opening only on the inner summit, a corolla approaching campanulate; 

 angular seeds, and a very peculiar habit. 



GiTHOPSis ^Specularioides; /?. hirsuta. Every part of the plant, except the 

 corolla, more or less hirsute : the capsule, with reflected hairs. 



Hab. With the above. 



*XYLOCOCCUS. 



Calyx five-parted, persistent, corolla cylindric-ovate, smooth within, the border 

 five-toothed. Stamina ten, included; filaments long and subulate, pilose; 

 anthers short and compressed, opening by two truncated pores, the summit
