 shortly petioled, lanceolate, coriaceous, 

 subentire, or spinulose-serrate; cau- 

 line spatulate-lanceolate, entire, pun- 

 gently acute: heads large, racemosely 

 disposed 1 in the axil of each cauline 

 leaf 'and 1 terminal; involucre broadly 

 hemispherical, %-% in. in diam., the 

 bracts in only 2 or 3 series, thin, line- 

 ar-lanceolate, acute, not notably herba- 

 ceous-tipped nor at all squarrose: rays 

 numerous: achenes unknown." Greene,

MALACOTHRIX IXSULARIS Greene. 



"Annual, glabrous, a foot or two 

 high, corymbosely paniculate above, 

 leafy below: leaves oblong-lanceolate 

 in outline, laciniate-cleft to the middle, 

 2 in. long, sessile and somewhat clasp- 

 ing: involucre hemispherical, less than 

 -,2 in- high, scales narrower and less 

 scarious than in M. Coulteri: corolla 

 yellow: akenes obtusely 5-angled and 

 15-ribbed: 1 or 2 of the pappus-bristles 

 persistent: those of the receptacle 

 sparse and short." Greene, Cal ac b

CALAIS PLURISETA Greene. 



"Glabrous: proper stem 2-4 inches 

 high: scapose peduncles 8-10 inches: 

 leaves very narrowly oblanceolate and 

 apparently quite entire, at most only 

 denticulate: akenes 2% lines long; pap- 

 pus paleae persistent, linear-lanceo- 

 late, 1V 2 lines long, scarcely notched, 

 the very slender awn 2% lines, sub- 

 tended by a secondary awnlet on either 

 side, one of these frequently one-third 

 as long as the primary, the other 

 shorter, or both nearly obsolete. Is-

MICROSBRIS BREVISETA Greene. 



"Small and slender, the foliage in re- 

 duced plants lance-linear and merely 

 toothed, in other pinnatifid: scapes 

 few. 3-6 in. high: involucres some- 

 what turbinate, achenes short and col- 

 umnar, less than 2 lines long, the outer 

 densely villous, the others dark chest- 



nut-brown, their ribs rather coarsely 

 and very roughly serrulate, paleae of 

 the pappus ovate-oblong, larger than 

 the achene. distinctly cymbiform, dull- 

 white, scaberulous, tapering to a very 

 short barbellulate awn." Greene, pitt

MICROSERIS PARISHII Greene. 



"Rather smaller and more slender than

MICROSERIS ELEGAXS Greene. 



Span or more high, slender, head less

NEMACLADUS CAPILLARIS Greene. 



"A span to a ft. broad and high, very 

 diffuse, the branches almost capillary, 

 glabrous throughout: radical leaves 

 spatulate-oblong; cauline linear-subu- 

 late, minute: pedicels capillary, divari- 

 cate or a little recurved: calyx-tube 

 slender, long-turbinate, adnate to the 

 lower half of the ovary, teeth ovate, 

 obtuse, half as long as the tube, a lit- 

 tle surpassed by the rounded summit 

 of the 7-12-seeded capsule: corona very 

 minute, white: stamineal tube distinct: 

 seed oblong-oval, 10-striate. with nu- 

 merous transverse lines forming dis- 

 tinct elongated reticulations." Greene,, 

 Cal ac b 1:1.96. Mohave Desert. 



NEMACLADUS PINNATIFIDUS Greene 

 "Glabrous throughout: radical leaves 

 linear-lanceolate, once or twice pinnat- 

 tified, the cauline coarsely toothed: 

 pedicels divaricate, abruptly bent up- 

 wards beneath the calyx: calyx-tube 

 short turbinate, the lanceolate teeth 

 surpassed by the rather acute 15-25- 

 seeded. oval capsule: seed short-ob-

 NEMACLADUS RUBESCENS Greene. 



"Glabrous, like N. capillaris, and 

 very similar in foliage and habit: ped-

 very short tube which is adnate to the 

 base only, of the globose, 20-40-seeded 

 capsule: corolla apparently open-cam-
