§. *Allophyllum. Annual. Leaves dissimilar and broad, obscurely three to 

 five-parted, with distinct partial petioles. Stem diffusely branched, the flowers 

 small, partly funnel-form, disposed in cymose racemes. Capsule oval, the cells 

 two-seeded; the seeds roundish, not angular. Closely allied to Collomia,h\it with 

 the cells of the capsule two-seeded. 



G. *DivARicATA. Annual, diffusely branched and subdecumbent, viscidly puberulous ; leaves alternate, 

 digitately united at the base ; leaflets three to five, lanceolate acute, attenuated into a petiole, two or 

 four much smaller than the others ; branches forked, ending in cymose racemes ; calyx obconic, 

 divided nearly to the base, enlarging with the ripening of the fruit ; the segments lanceolate acute, 

 viscid ; corolla small and slender, the tube more than twice the length of the small calyx ; segments of 

 the border oblong; stamens somewhat exserted, anthers roundish, stigma small. Capsule oval, not 

 extending beyond the short enlarging calyx ; seeds roundish, teeth two in a cell, rather large. 



Hab. Monterey, Upper California. 



§. *Chrysantha. Annual, pubescent. Leaves sessile, opposite, palmately 

 divided, with entire linear segments. B^lowers fastigiate, somewhat corymbose on 

 filiform peduncles, (yellow) segments of the calyx acute. Corolla funnel-form, with 

 a short tube, the segments oval and entire. Anthers ovate. Stamens exserted 

 beyond the throat of the corolla. Ovules in the capsule about twenty. 



G. *AUREA. Corolla smooth, about twice the length of the calyx ; segments of the leaves short and hispid, 

 three to six. 



A handsome and showy annual, growing about a span high, with short, hispid, 

 opposite sessile leaves, divided into five or six segments below, above about 3-cleft. 

 Stem mostly simple and branching above, the flower branches purplish and a little 

 viscid, terminating in compound trichotomous clusters ; peduncles slender, often near 

 an inch long. Flower apparently bright yellow, as large as that of many Phloxes, 

 funnel-formed, with a tube not exserted beyond the calyx, its base purple. The calyx 

 segments united two-thirds of the way, the teeth lanceolate and acute ; stigmas 

 exserted, long and filiform ; seeds about twenty in each capsule, when moistened 

 covered with a jelly as in Collomia. 



Hab. Santa Barbara. Flowering in April. 



§. *Elaphocera. Perennials or biennials, with the leaves often sparingly 

 pinnatifid towards the extremity, or entire and linear, fleshy. Flowers in condensed 

 clusters, capitate or in spikes, generally white. Corolla tubular, with a deeply 

 5-cleft, spreading border. Stamens shortly exserted or even with the summit of the 

 tube. Stigmas very short. Ovaries two to four in a cell, rarely one. 



G. coNGESTA. (Hooker.) Common in the Rocky Mountain region.
