LOASE^. 233 



capsules narrowly linear-clavate, %—% in. long : seeds very often in a 

 single row, short-prismatic, tlie 3 angles grooved, the sides only faintly 

 tuberculate. — Yosemite Valley and northward, chiefly to the eastward 

 of the mountains. It seems probable that M. Veaicliiatta, Kell. may be 

 identical witli this ; in which case that name must be ado^ated, as long 

 antedating M. dispersa. 



2. M. attiiiis, Greene, Pittonia, ii. 103 (1890). Near the last, but 

 stouter, ofteu 2 ft. high, simple and leafy below, widely branching above : 

 leaves lanceolate, deeply sinuate-pinnatifld : fl. scattered, Jo iii- broad : 

 calyx-lobes attenuate-subulate, 2 — 3 lines long : capsule 1 in. long, 

 almost linear, hispid with short stiff hairs which have a pustulate base : 

 seeds prismatical with grooved angles but relatively shorter than in the 

 last, and more tuberculate. — Plains of the San Joaquin, and far southward. 



3. M. micrautha, T. & G. Fl. i. 535 (1840) ; H. & A. Bot. Beech. 343. 

 t. 85 (1840), under Barlonia. Rather slender, 1 — 2 ft. high, simple below, 

 corymbosely and rather compactly dichotomous above : leaves ovate, 

 acute or acuminate, entire or serrate- or sinuate-toothed, 1 — 2 in. long : 

 fl. almost minute, shorter than the floral leaves : petals 5, oval, exceeding 

 the calyx-lobes : 5 of the filaments petaloid, with emarginate apex : 

 capsules cylindrical, or nearly so, 3 — 6 lines long, few-seeded : seeds 

 prismatical, the length about twice the breadth, the base often oblique, 

 the angles with a very shallow groove, the sides only faintly tubercu- 

 late. — Bather rare, but found at Clear Lak6, also on Mt. Hamilton, and 

 far southward. 



■i- -i— Seeds irregularly angled. 



4. M. albicaulis, Dougl.; Hook. Fl. i. 222 (1833) ; Hook. 1. c, under 

 Barlonia: M. Veatchiaua, Kell. fide, Wats. Stem low, branching from 

 the base or only corymbose, rather slender, % — 1 ft. high, white, 

 shining and almost glabrous : leaves remote, sessile, lanceolate, trom 

 deeply sinuate-pinuatifid to nearly entire : fl. small, solitary or in loose 

 clusters, not bracted : petals obovate, little exceeding the subulate- 

 lanceolate calyx-segments : filaments all subulate-filiform : capsules 

 narrow-cylindrical : seeds rather numerous (20—40), i.^' line long, tuber- 

 culate, irregularly and obtusely angled. — Eastern slope of the Sierra : 

 also at Ft. Tejou. 



5. M. coiigesta, T. & G. Fl. i. 534 (1840). Habit and foliage of the 

 last : flowers clustered at the ends of the branches, half hidden by broad 

 toothed bracts which are scarious at base : petals }4— ) 2 in- long : fila- 

 ments all filiform : capsule clavate, 3^3 in. long : seeds nearly a line long, 

 tuberculate. — East of the Sierra only. 



6. M. gracilenta, T. & G. 1. c. Less branching, 1—1^4 ft. high, 

 stouter : leaves narrowly lanceolate, pinnatifid with many narrow lobes,
