268 Onagraceae 



or rarely faintly and remotely repand-denticulate ; flower- buds 

 drooping, elliptic-ovate, tapering above to a rather long acuminate 

 tip, 10-15 mm. long; calyx-tube 1.5-2 mm. long; petals obovate, 

 truncate at the apex, abruptly tapering near the base to a short 

 (2 mm. long) and narrow claw, 15-20 mm. long, pink, often with 

 purple specks below the middle; stamens slightly unequal, the 

 longest 12 mm. long, anthers yellow; style filiform, glabrous, 

 12-14 mm. long; stigma-lobes oblong, 1.5 mm. long, yellow; cap- 

 sule linear, abruptly tapering at base to a short pedicel, and at 

 the ape* to a slender beak, about 2.5 cm. long, each cell laterally 

 bicostate. 



Frequent in the upper portions of the chaparral belt of the San Gabriel 

 Mountains. The type is the author's number 2635, collected in the Little 

 Santa Anita Canyon at 2500 feet altitude. This species has been confused 

 with G. Bottae, but it is much nearer G. hispidula Wats. 



5. G. epilobioides (Nutt.) Wats. Stems slender, somewhat 

 branched above, 3-5 dm. high, glabrous or nearly so; leaves 

 linear or linear-lanceolate; calyx-tube 4-6 mm. long; petals 

 cream-colored or rarely faintly tinged with rose, 8-10 mm. long, 

 rounded at apex or somewhat acutish ; stigma-lobes short ; cap- 

 sule 15-25 mm. long, acuminate at apex, attenuate at base to a 

 short base or nearly sessile, not costate. 



Common in the chaparral belt, especially toward the coast. First col- 

 lected by Nuttall at San Diego.

 tips free in the bud. Petals 4, spreading. Stamens
