 Cat. 46. G. ylomeratum, Thuill. as used by Hooker, f. and others. 

 G. connatum, Beck, JBot. 55. Depauperate forms with few flowers 

 and short capsule have been regarded as indigenous, being the 

 G. viscosum, var. tenellum, Grenier, 1. c. 266, and the G. semidecan- 

 drum^ auct. (not of Linn.). — Widely distributed in the United States 

 and Canada, but much less common than the following; probably 

 introduced from Europe. Delicate specimens apparently to be referred 

 to this species, but with minute apetalous flowers, have beeu collected 

 at San Diego, Calif., Orcutt. 



C. vulgatum, L. (Common Mouse-ear Chick weed.) Peren- 

 nial, viscid-pubescent, a little taller and more spreading than the last : 

 leaves oblong, obtusely pointed : flowers larger : the lower pedicels in 

 fruit considerably exceeding the calyx : bracts herbaceous : sepals 2-3 

 Jines long, obtuse, often purple-tipped, appearing acute through the 

 infolding of the scarious margins : petals as long as the calyx. — Spec.

 Decouv. 36. G. triviale, Link, Enum. Hort. Berol. i. 433. — Very 

 common in fields, etc., but also often remote from habitations and 

 cultivated ground, thus perhaps native. Flowering through the 

 summer. 



C. semidecandrum, L. Near the two preceding, but smaller and 

 with shorter leaves : the bracts, at least the upper ones, conspicuously 

 scarious-margined : pedicels in fruit longer than the calyx. — Spec. 

 438; G vulgatum, var. ? semidecandrum, Gray, Man. ed. 5, 94. —

 ventive from Europe.) 



-t- -t- Pods 2-3 times as long as the calyx : indigenous species. 



C. brachypodum. Pale green, finely pubescent and sometimes 

 very viscid : leaves linear-oblong to oblanceolate, obtusish, seldom more 

 than an inch in length : flowers in more or less open dichotomous cymes ; 

 pedicels, even the lower ones, only equalling or little exceeding the 

 capsules, erect or deflexed, straight or gently curved, not hooked. —
