oblong scales of the pappus are nearly as long as the tube of the corolla, but are con- 
cealed by the long villous hairs of the achenium.* 
* Chenactis denudata, Nutt. in Jour. Acad. Philad. (n. ser.) 1. p. 177, from Pueblo de los Angelos, Cali- 
fornia (fide spec. in herb. Lowell.), is the same as C. lanosa, DC. The subjoined appears to be an un- 
bed species : — 
Cwenactis Fiuirotia (Harv. §& Gray, in Pl. Coult. ined.): subarachnoidea, demum glabrata ; caule 
corymbosi-ramoso usque ad apicem folioso; foliis pinnatipartitis (summisve simplicibus); segmentis 5—- 
9 rachique filiformibus integerrimis ; pedunculis brevibus non glandulosis; corollis (flavis) radiantibus infundi- 
buliformi-ampliatis irregularibus discum non superantibus ; pappi paleis 4 oblongis obtusis equalibus. — Cali- 
fornia, Coulter. — Heads about as large as in C. lanosa. Lobes of the leaves entire, more slender and sparse 
than in C. tenuifolia. In that species the scales of the pappus in the disk~are unequal, lanceolate, and acute 
or acuminate. In this they are much shorter and broader, obtuse or rounded, and erose at the apex, espe- 
cially those of the ray. — There is another species in Fremont’s, and also in Hartweg’s, Californian collection, 
which is exceedingly well marked by the great inequality in the palew of the pappus, viz. : — 
C. nererocarpna (Torr. § Gray, Fl. ined.): annua, nana, lanosa, demum glabrata; caule folioso 
plerumque simplici monocephalo ; foliis pinnatipartitis, segmentis 4-9 anguste linearibus breviusculis inte- 
gerrimis rachi subangustioribus ; pedunculo eglanduloso capitulum majusculum eximie radians vix duplo ex- 
cedentibus; corollis (aureis) radiantibus infundibuliformi-ampliatis, limbo irregulari discum superante ; achenio 
hirsuto; pappo disci e paleis 4 lanceolato-oblongis obtusissimis corollam zquantibus et 4 alternis parvis obo- 
vatis 5—6-plo brevioribus. — California, Fremont (third expedition), Hartweg (no. 1792).— Plant 3 to 5 
inches high, rather slender, leafy to within an inch of the head, the stronger specimens inclined to branch 
above and bear one or two additional heads. Leaves an inch and a half long; the lateral lobes two or three 
lines in length, almost filiform. Head larger than in C, lanosa, nearly equalling that of C. achillezefolia ; in- 
volucre half an inch long. The somewhat palmate limb of the radiant corollas is four lines broad when ex- 
panded ; the lobes as long as the tube. Pappus of the radiant flowers as in the disk, but shorter. 
The following appears to constitute a distinct genus, which should probably stand (perhaps with Amauria, 
Benth.) next to Chenactis rather than with the Madiem, notwithstanding the total absence of pappus. 
ACARPHEA, Harv. & Gray, in Pl. Coult. ined. 
Capitulum multiflorum, homogamum ; fl. omnibus tubulosis, exterioribus ampliatis subradiantibus. Involu- 
¢crum campanulatum circ. 24-phyllum; squamis biseriatis, lanceolatis, discum equantibus, planis. Recepta- 
culum nudum, planum. Corollz, tubo glanduloso-pubescente, disci graciles 5-dentate ; radii sursum infundi- 
buliformi-ampliate, 5-lobze, limbo subirregulari. Antheree exsertee. Styli rami filiformi-subulati, hirtelli (ut in 
Cheenactide). Achenia omnia (ut videtur) fertilia et conformia, lineari-clavata, subcompressa, multistriata, 
_ glabra, calya, extima paulo incurvata, in squamis involucri haud occulta. — Herba erecta, viscido-puberula ; 
foliis alternis 2 —3-pinnatisectis ; capitulis paniculato-corymbosis; floribus luteis. 
_ A. anremisixroria, Harv. §- Gray, I. c. — California, Coulter. — Herb apparently three feet high, naked 
above: the root unknown. Leaves 3 or 4 inches long, petioled, glandular-hoary, especially underneath ; the 
pinnz, segments, and lobes linear or oblong, obtuse, numerous and approximate. Involucre half an inch long 
the outer scales herbaceous ; the inner narrower and more scarious, not complicate. Marginal corollas scarcely 
longer than the others. The achenia are immature, but apparently all fertile; the outer are not at all involved
