rely in distinguishing the species, are the shape, size and (E. 

 fabacea) the color of the corollas, the simple racemes or branch- 

 ing panicles of the sterile flowers, and the shape of the seeds. 

 The leaves show differences but they are not so clear nor ap- 

 parently so reliable as the distinctions above noted. 

 TWO NEW SPECIES. 



Hemizonia (Calycadenia) seciosa. Plant 2-4 feet high, very 

 branching, with very slender, spreading, almost wholly glabrous, 

 branches and branchlets. Tack-shaped glands few, principally 

 on the tips of the very small leaves in the branchlets. Stem 

 leaves narrowly linear, about an inch long, thickish, entire, 

 usually puberulent, with strong white midvein. Heads not 

 involucrate, solitary at the ends of the branchlets which are often 

 3 or 4 inches long, pale yellow, showy. Involucre consist- 

 ing of 10-15, more or less, imbricated bracts, which are oblong 

 varying to oblong-spatulate in shape, thickish and stiff m 

 texture, with more or less glaucous bloom, the inner and larger 

 series scarcely connate, abruptly truncate with cuspidate ciliate 

 tips. Rays about 5, nearly an inch long. Disk flowers 10-20, 

 infertile, without pappus. Akenes blackish, obovoid-tnangular, 

 somewhat curved, with wholly smooth but deeply wrinkled and 

 pitted surfaces. . 



A showy species, allied to H. truncata Gray, but very distinct. 

 Open fields near Roseville, Cal. 



Muilla tenuis. Corm % inch in diameter, about an 

 inch deep in the ground. Stem very slender with membranace- 

 ous sheaths at base, 6 to 12 inches high. Leaves filiform, 

 of extreme tenuity, 3 to 6 inches long. Umbel 12-15-flow- 

 ered. Pedicels very slender about an inch long. Bracts at base 

 of umbel 4-6, 3-4 inches long, long-acuminate. Flowers about 

 2 lines in diameter, whitish. Sepals oblong, obtusish, 

 the wide midvein of a yellowish brown. Filaments filiform. 

 Anthers oval, versatile. Capsule depressed -globose, slightly 

 3-lobed. Seeds few, flattened on one side, irregularly angled. 



A verv slender species differing from M maritima in the extreme 

 slenderuess of all its parts and the different sepals. Foothills, 

 Raymond, April.
