 many-flowered; petals rose-purple, 4-8 mm. long, capsule 2-5 cm. 

 long, slender, attenuate above, contorted; seeds ash color, minutely 

 pitted. (0. alyssoides H. & A.) 



Occasional in the chaparral belt. Echo mountain, Davidson;

10. GAYOPHYTUM Juss. 



Erect very slender diffusely branching annuals, with

 Stamens 8, the alternate ones usually minute and sterile; 

 filaments filiform; anthers subglobose, fixed near the 

 middle. Ovary oblong or linear, compressed, 2-celled; 

 stigma capitate or clavate. Capsule membranous, 

 clavate, 4-valved. Seeds few-many, in 1 row in each 

 cell, smooth, naked, mostly oblong. 



Seeds canescent with appressed pubescence. 1. G. lasiospermum. 

 Seeds glabrous. 



Capsules on filiform pedicels. 2. G. ramosissimum. 



Capsules subsessile, 3. G. caesium. 



1. G. lasiospermum Greene. Stems 2-4 dm. high, loosely 

 dichotomous with filiform branches, the upper leaves and inflores- 

 cence canescent with appressed or spreading hairs; petals about 

 1 mm. long; capsules erect, about equaling the subtending leaves, 

 narrowly linear or slightly clavate, scarcely torulose; seeds erect, 

 finely appressed-pubescent. 



Open pine forests in dry situations; North Baldy; San Jacinto 

 Mountains. 



2. G. ramosissimum T. & G. Stem intricately dichotomous 

 with filiform branches 15-60 dm. high, glabrous below, appressed 

 canescent above or rarely with spreading hairs throughout; leaves 

 mostly narrow, usually appressed against the branches; petals 

 nearly white, turning rose color, 1-2 mm. long; stigma about 0.4 

 mm. in diameter; capsule about 1 mm. thick, oblong to subclavate, 

 often torulose, erect or refracted on filiform pedicels; seeds nearly 

 erect in a single series, papillate, 0.5 mm. broad, 1.3 rnm. long. 



Common in the coniferous forests in all the mountains. 



3. G. caesium T. & G. Stems with mainly erect or ascending 

 branches, 1-3 dm. high, leafy, glabrous or pilose; petals scarcely 1 

 mm. long; capsules nearly sessile, erect, narrowly linear; seeds 

 smooth.
