densely spreading-hirsutulous; s. Sierra Nevada and Tehachapi 



Mts 28. L. nashianus. 



Leaf -segments oblanceolate ; corolla 4 to 6 lines long, its lobes quadrate, trun- 

 cate or emarginate ; flowers in terminal clusters, occasionally 1 or 2 in 

 the uppermost axils; upper Kern River basin 29. L. olilaiiceolatus, 



1. L. maculatus Mlkn. Stem branched from the base, % to I14 inches high, 

 sparsely pubescent, equably leafy ; leaf -blades oblong-linear, entire, cuspidate, thick, 

 puberulent above, glabrous below, 1 to 2 lines long; earlier flowers subsessile in the 

 lower forks, the later ones crowded above in small head-like clusters; calj'x parted 

 almost to ba.se, nearly equaling the corolla-lobes; calyx-lobes oblong-linear, ciliate, 

 with a hyaline margin, evidently unequal, cuspidate ; corolla campanulate, white, 

 2 lines long, the lobes broader than long, about % as long as throat and tube ; sta- 

 mens included in throat, inserted at the summit of the very short proper tube; 

 capsule oval, the cells several-seeded ; seeds unchanged when wetted. 



Sandy flats and washes, 500 to 2200 feet: northwest arm (Conchilla Desert) 

 of the Colorado Desert and desert floor on the north side of the Conchilla Mts. 

 Mar.-Apr. 



Note on endemism. — Linanthus maculatus is a narrow endemic restricted to the flats and 

 valleys bordering the Conchilla Range, that is, the Conchilla Desert on the south side and the 

 desert floor on the north side. Not only is it a narrow endemic, but the number of stations for it 

 and the number of individuals of it appear to be limited, five collections only being known to us: 

 "Whitewater River, Wilder 704 ; probably Conchilla Desert, Wright 1820 (bearing no exact station, 

 but S. B. Parish says that Wright on this trip from San Bernardino went no further into the Colo- 

 rado Desert than Palm Springs and its immediate valley floor) ; Coyote Holes (Bull. S. Cal. Acad. 

 24:50); betw. Morongo Valley and Twentynine Palms, Daniels; Twentynine Palms (8 mi. s.), 

 J. Kech 3843.

2. L. demissus Greene. Stem branched from or near the base, the branches 

 ascending, 1/2 to 3 inches long, equally leafy throughout; herbage glabrate or thinly 

 puberulent, sparingly and microscopically glandular; leaves trifidly divided with 

 spreading or divergent lobes, or entire, the blade or its lobes linear, conspicuously 

 cuspidate, 2I/2 to 5 lines long ; flowers in close leafy cymes, short-pediceled ; calyx 

 divided nearly to base into lanceolate lobes with hyaline or white-scarious margins, 

 exceeding the corolla-throat; calyx- tube below sinuses searious; corolla campanu- 

 late, white with purple-streaked throat, 2i^ to 4 lines long; corolla-lobes quadratish- 

 oblong, % as long as throat, the proper tube very short, pale yellow, the stamens 

 inserted almost on its summit, about as long as corolla-throat; capsule oblong-oval, 

 1/2 as long as the calyx ; cells several-seeded ; seeds unchanged when wetted. 



Desert plains and cailons, 2000 to 7500 feet: eastern Mohave Desert; south- 

 eastern Inyo Co. East to Arizona and Utah. Apr. -May. 



Flower note. — The lobes of the corolla are a little twisted and thus resemble the fans of a 

 turbine windmill. The calyx-lobes are unequal, 3 large and 2 sm.nll.
