branch leaves pinnate lobed, toothed or entire linear-lanceolate, 

 sessile. 



Rajs, twenty-five or more, (all fertile) in two series, obovate, 

 sub-cuneate three-cleft toothed, the middle tooth or lobe much 

 narrower (rarely two or four-toothed) ; tube long, slender, inserted 

 laterally at the obtuse summit of the achenia by a short, somewhat 

 beaked ascending areola, stipitate glandular ; branches of the style 

 long, filiform, glandular. 



Involucral scales at the rays, carinate-infolded, nearly enclosing 

 the ray achenia, subtended by short linear foliaceous erect bracts ; 

 outer series more strongly carinated, hairy, and densely stipitate 

 glandular. 



Ray achenia, as seen in the figure ; strongly Incurved, stipe 

 somewhat inflexed, back slightly rugose, glandular, laterally ridged' 

 or obscurely triangular (otherwise generically described). 



Chaff in a single series of about twenty united scales between 

 the disk and ray flowers, tips herbaceous, green and glandular, 

 like the persistent involucre (even in the fully matui-ed heads). 



Corolla of the disk (yellow) five-toothed ; teeth glandular- 

 bearded above, funnel-form, with a slender stipitate glandular tube. 



Disk achenia perfect but infertile, cylindrical, attenuate below, 

 stipitate glandular ; pappus obsolete, or only few very minute, trans- 

 parent, laciniate squamellae ; anthers dark brown, or nearly black ; 

 branches of the style exsert (yellow) very hispid, filiform ; append- 

 ages also hirsute. 



Receptacle convex, fimbrillate-hirsute. 



A numerously branching California herb, of the class commonly 

 known as "Rosin Weeds," from their densely viscid-glandular 

 character so notorious during our autumnal season. This plant 

 exhales a fragrant balsamic perfume, etherializing and enrapturing 

 the senses into a state of sweet tranquility ; hence the specific 

 name, haUamifera. 



It differs from the generic description of Hemizonia (T & G) 

 in its receptacle, not being " flat ; " but this also is the case with 

 H. pungens, which, like our plant, has even a conico-convex recept- 

 acle ; besides, the receptacle" is fimbrillate hirsute. The involucral 

 scales in our plant are in two series — not in a " single series " — 

 consequently, also the rays. This biserial arrangement gives the 

 rays the false appearance, as if each alternate petal were longer. 

 Notwithstanding these and other minor discrepancies, we are unwil- 

 ling to institute a new genus.
