BOTANY. [109] 53 
Hemizonta Fitcnt (sp. nov.): annua, pilis longissimis patentibus arachnoideo-villosa; caule 
rigido erecto superne demum ramoso ; foliis caulinis elongatis pinnatifidis vel pinnatipartitis, 
(imis nunc fere bipinnatipartitis,) summis et ramealibus subulato-linearibus integerrimis seu 
rariter dentatis rigidis pungenti-cuspidatis, floralibus capitulum sessile arcte involucrantibus et 
bis superantibus ; involucri squamis 7-9 subulatis glandulis nonnullis parvis claviformibus ob- 
-sitis ligulis oblongis apice bidentatis flavis paullo brevioribus; floribus disci (plusquam 30) 
omnibus paleis receptaculi oblongis scariosis muticis ad apicem herbaceum longe crinitis fulcratis ; 
pappo (fl. disc. ster.) corollam subsequantibus e paleis 8-12 auguste linearibus rigidis basi in 
tubum vel in phalanges sepius pl. m. coalitis superne fimbriato-barbatis ; ovariis radii apice 
valde gibbosis. Plains of the Sacramento, California; May ; where it was previously detected 
by the Rev. Mr. Fitch. A well-marked and peculiar species, which will fall into none of the 
sections of the genus, as they are limited in the Flora of North America; but in some respects 
it approaches that section of Calycadenia which is formed of Nuttall’s Osinddonia, and of which 
some additional species are now known. The present plant has a rigid and usually stout stem, 
from three to twelve inches high, at first simple, and terminated by a single sessile head, (of 
about an inch in diameter,) at length corymbosely branched, often from within the circle of 
involucrate leaves, so as to appear proliferous. Cauline leaves of linear outline, two to three 
inches long ; the rigid and springy-pointed rameal ones an inch or less in length, often fascicled. 
Ligules three lines long, including the tube. Lobes of the disk-corolla short, ovate. Recep- 
tacle chaffy throughout; the pale distinct, partly wrapped around the disk-flowers, The very 
immature fertile achenia are obovate-trigonal, with a short inflexed stipe, a large dorsal hump, 
and a short inflexed apical beak. 
Hemizonra conaesta, DC. Prodr. ‘By p. 692. Caliente: Besides these specimens, I have 
seen no indigenous ones except those of Douglas, who seems to have collected it sparingly. I 
have, however, a specimen taken from a plant raised in the Cambridge Botanic Garden, in 1850, 
from seeds received the previous year from the London Horticultural Society, under the name of 
‘‘ Madaria corymbosa.’ Indeed, it is distinguishable from Madaria by the shape of the fertile 
achenia alone. The foliage and young parts are more cinereous and soft-downy than i in Ma- 
daria, and many of the leaves are serrulate-toothed.'

covered the fact and united the ia ek omitted to erase the species under Hartmannia from his manuscript. '
