42 Contributions from the Gray Herbarium 
1914, C. H. T. Townsend 1511 and 1518 (U.S. Nat. Herb.); with- 
out definite locality, Née (type of H. sericeum DC.: hb. Prod.), 
U.S. Exploring expedition under Wilkes (Gray Herb.). According 
to Dr. Weberbauer’s label the plant is a shrub, but the specimens 
have rather the appearance of a barely suffrutescent perennial; 
Mathews describes it as a ‘‘ perennial herb.”’ 
The name of this genus is derived from ovyxpnrticpos, a blending 
of unlike elements, and xapz6s, fruit, in reference to the peculiar 
combination of characters presented by the ripe achene. 
ALVORDIA angusta, sp. nov. Fruticosa ramosa, caule brunneo

— Lower Cauirornia: Todos Santos, 29 Jan. 1889, Brandegee 
(corypEs in Gray Herb. and U.S. Nat. Herb. no. 342433); Cape 
Region, Nov. 1902, Brandegee p.p. (U.S. Nat. Herb. no. 397921). 
The first collection above cited was distributed as A. glomerata 
Brandegee, the second includes A. fruticosa Brandegee. Both A. 
fruticosa and A. angusta are easily distinguished from A. glomerata, 
the type species of the genus, by the smaller involucre with bracts 
merely marginally ciliolate (densely strigillose on back as well in 
A. glomerata), the smaller achene with shorter pappus, and the 
absence of rays. A. fruticosa as originally described (Erythea vil. 
5 (1899)) included the species here separated as A. angusta, the 
description of the leaves and achenes referring better to the former, 
of the solitary disk-floret to the latter. No type is cited, but its
