PLANT& FENDLERIAN. 81 
spines, with two terminal and thicker, but scarcely longer ones, forming beaks, much as 
in Xanthium. — The vestiges of the lower cauline leaves in the specimen show that 
these are more or less bipinnately parted, so that the plant is likely to be the Ambrosia 
tomentosa of Nuttall’s Genera,— which is known only by the incomplete character 
given in that work, and which has not since been recognized.

Rayado Creek. (400.) — A dwarf, suffrutescent, eminently showy species, bearing an 
abundance of flowers through the whole season; the rounded, light-yellow rays two 
thirds of an inch in length, around a narrow, orange-colored disk. Some of the achenia 
bear a short fimbrate-laciniate awn, and a bristle or two in place of the second: others 
bear a little tuft of a few bristly hairs in place of the awns. The chaff is petaloid and 
orange-colored at the tip.*

* Dr. Torrey has re-described and figured it in Emory’s Report (plate 4). The following is a very 
dwarf, apparently undescribed species of the same habit, from Dr. Gregg’s collection : — 
ZINNIA PUMILA (sp. nov.) : cespitosa e caudice suffruticoso, depressa ; caulibus 2—4-uncialibus ramosis 
conferte foliosis, hirsutis ; foliis anguste linearibus uninerviis impresso-punctatis margine cartilagineis scabris 
basi connatis internodiis multo longioribus nunc fere imbricatis ; capitulis parvis brevissime pedunculatis ; in- 
yolucri squamis rotundatis ; ligulis ovalibus luteis ; paleis receptaculi obtusissimis apice suberosis ; acheniis 
disci uniaristatis aut subbiaristatis margine cum basi ariste ciliatis. — High plain near San Juan de la Vequeria, 
and at Castaniola, in Northern Mexico, Dr. Gregg. — More dwarf and condensed than Z. grandiflora; the 
leaves half an inch long. Head three tenths of an inch in length; the pale-yellow rays about as long as the 
involucre, perhaps not persistent. 
+ Specimens of Heliopsis levis, y. seabra, Torr. § Gray, from Arkansas and farther westward, often show 
the rays persistent until the achenia are mature, and have an obscure coroniform pappus, much more marked 
than in the Eastern plant. In Mr. Spalding’s Oregon collection occurs an undescribed Heliopsideous plant, 
which has the same relation to Balsamorrhiza that Kallias, Cass., has to Heliopsis proper : — 
BALSAMORRHIZA § KALLIACTIS. Ligule marcescenti-persistentes. Achenia pubescentia. — Cau- 
lis bi - pluriflorus, parce foliatus ; foliis integerrimis. 
B. Careyana (sp. nov.) : cinereo-puberula, subscabra ; caule erecto apice subvilloso 2- 8-cephalo; foliis 
longe petiolatis adultis scabris reticulato-venosis, radicalibus cordato-hastatis repandis, caulinis 3-7 parvulis 
lanceolatis subtrinervatis sparsis imisve oppositis ; involucri squamis biseriatis lanceolatis appressis villosulis 
ligulis circiter 12 ovalibus emarginatis multinerviis inferne puberulis discum
