long; flowers purple, rather large. This grows scatteringly 

 throughout the region from Lone Pine to the Argus Mts., Cal. r 

 on gravelly mesas, usually under desert shrubs which give it 

 support as it straggles up through the open branches, when 

 growing alone it is shorter and less flexuous. Darwin Mesa, 

 Argus Mts., 5000 ft. alt., May 8, 1897, etc, 



Arabis pulchra var. gracilis. More slender, flowers 



about y% as large, pods glabrous and flattish even when young 

 while those of the type are round when young and not at all 

 flattened. Shepherd's Canyon, Argus Mts., Cal., 4800 ft. alt., 

 May 1, 1897. 



Arabis dispar n. sp. Perennial from a woody casspitose 

 base, crowns many, fasciculately leafy, with very many small 

 blades 4 to 8 lines long, entire, spatulate, acute, densely stellate 

 leaves which taper into channeled, slender, green, margined 

 petioles which are enlarged and fleshy at very base, petioles 

 usually twice to thrice the blades; slender, simple stems 6 

 inches high, erect, with internodes about as long as the broadly 

 linear, sessile, not clasping nor auriculate, acute stem leaves 

 which are 6 to 12 lines long and not reduced above; flowers few, 

 in small heads which become short racemes in fruit, purple, 2^ 

 lines long, erect, puberulent; sepals purplish, elliptical-oblong, 

 obtuse, hyaline margined, '- shorter than the purple, narrowly 

 oblong, veined petals; pedicels in fruit 4 lines long, stout, as- 

 cending; pods smooth, erect, 3 inches long, ^ line wide, flat, 

 not tapering nor acuminate at apex, and style none, in immature 

 pods the tip is a trifle narrowed, nearly straight; seeds nearly 

 in one row, not margined. This appears to be nearest to A. 

 Parishii Robinson. It grows on rocky hillsides in Pleasant 

 Canyon, Panamint Mts., Cal., 5500 ft. alt., May 6, 1897. 



Ceanothus Maruni n. sp. Slender open branched shrub 

 with gray bark, thornless, young stems closely pubescent, whole 

 plant otherwise glabrous; leaves oval to nearly round, generally 

 emarginate, thin, truncate to very short cuneate at base, slender 

 petioles 2 to 3 lines long, stipules subulate, deciduous, leaves 

 palmately 3-nerved, not resinous, scarcely paler below, minutely 

 toothed except at base, flowers from the season's growth, spikes
