£. canescentis. Involucri squame 2-3-seriales, ineequales, virides, membranacee, minute puberule, margine 
presertim basi ciliate, interiores discum subequantes. Ligule circa 12, oblongee, extus pubescentes, neutree. 
Receptaculum planum. Palese membranacem, naviculares, floribus disci paullo breviores. Corolle disci 
glabree, tubi parte tenui brevissima, fauce tubulosa elongata, dentibus brevibus incrassatis, Styli rami

similibus raris onustis. 
Allied to E. californica, but neither the form of the leaves, nor the clothing of 
the involucres agree with the character given to that species. 
89. ENcELIA nivea, sp. n., procumbens, tomento subsericeo niveo, foliis plerisque oppositis 
petiolatis ovatis obovatisve, pedunculis elongatis 1-2-cephalis, involucri squamis ovato-lanceolatis 
extus sericeo-tomentosis, achzeniis compressiusculis breviter villosis marginibus vix ciliatis—San 
Quentin. 
Rami laxiores et longiores quam in HZ. conspersa, tomento molli albo obtecti, vix demum subnudi. Folia 
vix pollicaria, obtusissima, integerrima, margine subundulata, basi in petiolum 3-6 lin, longum angustata, 
crassiuscula, molliter niveo-tomentosa, nervis 3 subtus prominulis; fere omnia opposita, pauca hine inde 
presertim sub pedunculis alterna, Pedunculi semipedales, rigiduli, seepius 1-2-bracteati at simplices, rarius 
ramo monocephalo ad axillam bracteee aucti. Capitula hemispheerica, quam in Z. conspersa paullo majora, 
Squamz involucri biseriales, exteriores paullo breviores, subfoliacese, apice subpatentes, cano-tomentose. 
Ligule circa 10; lamina 4 lin. longa, ovato-oblonga, integra, multinervis, glabra, Palese lineari-lanceolate, 
carinate, disco paullo breviores. Corolle disci et genitalia? H. conspersw. Acheenia vix perfecta vidi, sed 
multo minus compressa sunt quam in specie preecedente, villis minus ineequalibus, 
This species differs slightly from other Encelig, in having its leaves mostly 
opposite, and the achznia, so far as can be ascertained from very young ones, 
and from a few others very old and somewhat injured, are much less compressed, 
with the hairs more equally diffused. These characters bring it near to Gymnop- 
sis, but the habit is in other respects that of Encelia, and I can see no trace of 
any coroniform pappus. Perhaps the two genera are not sufficiently distinct.
