200 Eastwood : New species of western plants 



eels of all except the earliest shorter than the calyx; bracts 3- 

 parted with linear-attenuate divisions, the upper simple ; bractlets 

 minute, linear-attenuate : calyx orbicular-campanulate, 3 mm, 

 long in flower, 5 mm. in fruit, the divisions i mm. long, varying 

 in width in the same flower from 1-2 mm.; tube rounded or 

 slightly cuneate at base : petals white, oblanceolate, obtuse, nar- 

 rowed to a bulb-tipped base : filaments rather broad, inserted 

 lower on the calyx-tube than the petals and surpassing them ; 

 anthers yellow, orbicular : style and ovary puberulent, stigmas 

 capitate and later becoming bulbous, exserted and strongly divari- 

 cate : seeds brown, oblong or elliptical, echinate, 0.5 mm. long.

Lithophragma trifoliata sp. nov. 



Stems from slender, running rootstocks, striate, scabrous-his- 

 pid, upper part clothed with gland-tipped hairs, generally 2-leaved 

 and about 3 dm. high : radical leaves with long, lax, glandular- 

 hispid petioles, dilated and sheathing at base, erosely ciliate ; blade 

 orbicular in outline, the 3 palmate divisions tapering to a slender 

 base, each with 3 or 4 cuneate lobes with margin crenate the crena- 

 tures callous-apiculate, scabrous on both sides, low^er leaves often 

 simpler ; cauline leaves on short petioles with broad, membranous, 

 erosely ciliate stipules, the blades with sharper and narrower 

 divisions than the radical leaves : flowers few, in short subcapitate 

 racemes ; bracts white-membranous, enclosing the base of the 

 petioles, about I mm, long, twice as broad, sparingly ciliate, pedi- 

 cels erect, shorter than the calyx, about 3 mm. long ; calyx tur- 

 binate, attenuate at base, broadest at the insertion of the petals and 

 stamens, the divisions conniving and narrowing the calyx at the 

 top, triangular, apiculate, as long as the part of the tube above the 

 ovary: petals 3-lobed to below the middle; blade 7 mm. long: 

 the lateral divisions linear, acute, the terminal obovate, obtuse, 

 claw slender, 3 mm. long : ovary half-included, the stigmas broad, 

 sessile. 



Collected by Mrs. R. M. Austin in Modoc County, also by 

 her daughter, Mrs. C. C. Bruce, in the foothills near Chico, Butte
