208 PROCEEDINGS OP THE AMERICAN ACADEMY 



like the sparse and softer leaves, wholly destitute of the nail-headed 

 glands wliich conspicuously appear on most specimens of the species 

 now recognized, though sometimes they are few and small. The corol- 

 las are plainly yellow, more so than in dried specimens of L. Germaao- 

 rum, which according to Chamisso are satFron-colored. The original 

 species we have only from the neighborhood of San Francisco. 

 L. glanduUfera occurs from ^lonterey to San Diego, Owens Valley, 

 San Bernardino, &c. Fine specimens from the latter district, col- 

 lected by the Brothers Parish and Mr. Pringle, have directed my 

 attention to the species, which I had confounded with two others. 



Grindelia costata. Elata, glabra, la^vis ; ramis gracilibus mo- 

 nocephalis ; foliis fere membranaceis lanceolatis acutis serrulatis basi 

 auriculis breviter adnato-decurrentibus semiamplexicaulibus ; capitulo 

 hemisphajrico semipollicari ; involucri bracteis brevibus subulatis de- 

 mum squarroso-recurvis raodo G. squarrosce ; acheniis (lineam longis) 

 Isevibus lunato-gibbosis vel incurvis circa 10-costatis, costis plerisque 

 crassis (valleculis angustissimis) obtusis, ventrali cariniformi ; areola 

 epigyna parvula. — Northern Mexico, near Juraz, in Coahuila, 100 

 miles north of Monclova, Palmer, no. 472. 



Grindelia subdecdrrens, DC, is a species which should like- 

 wise be well distinguished by the akenes : these in De Candolle's s[)eci- 

 mens are at maturity so turgid as to be globular, are without ribs and 

 almost without angles, the slightly depressed terminal areola rather 

 large. Specimens which have been referred to it, with immature fruit 

 more prismatic, may probably belong to G. squarrosa. 



Grindelia Arizonica, Gray, as yet unpublished (to which be- 

 longs Q. microcephala, Rothrock in Wheeler Rep. 141). of which ripe 

 fruit is still wanting, appears to include no. 467 of Palmer's North 

 Mexican collection. 



Acamptopappus Shockleyi. Frutex humilis, ah A. sphcerocephalo 

 differt capitulis majoribus hemispha^ricis in pedunculo gracili ramos 

 patentes terminante solitariis radiatis ; ligulis circiter 12 (oblongis 

 semipollicaribus luteis) ; involucro minus imbricato ; pappo achenio 

 paullo longiore. — Western Nevada, near Candelaria, Esmeralda Co., 

 W. S. Shockley. 



Bigelovia intricata. Suffrutescens, divergenti-ramosissima, 

 glaberrima, parce sqnamoso-foliata ; ramulis gracillimis monocephalis; 

 foliis crassiusculis subulatis soepius mucrone apieulatis, majoribus semi- 

 pollicaribus, ramulinis minimis squamiformibus ; capitulis (lin. 3-4 

 longis) 12-15-floris; involucro campanulato, bracteis sat numerosis
