84 PLANTZ FENDLERIANE. 
1395. H. rracneturouwus, Willd.; Torr. § Gray, l. c. Creek bottom, 30 miles 
east of Council Grove; Aug.* (431.) 
7396. Hetiomeris muxtirLora, Nutt. in Jour. Acad. Philad. (n. ser.) 1. p.171. Bot- 
tom land, seven miles east of Rock Creek, New Mexico; Aug. (432.) —The plant, 
which much resembles a Helianthus of the Microcephali group, or H. Nuttallii, is just in 
flower, and has no full-grown fruit. There is no trace of a pappus. — The same species 
was gathered by Dr. Wislizenus at Llanos, in the Sierra Madre, and a variety, or second 
species, occurs in the collection made by Fremont in his third expedition.t (This is 
probably the plant enumerated as Wulfia? in Dr, Torrey’s appendix to Emory’s Report.) 
* Dr. Gregg’s collection contains the well-marked H. ciliaris, DC., gathered from near Berlandier’s hab- 
itat, and an undescribed species, belonging apparently to the Atrorubentes, viz. : — 
HELIANTHUS LaciINIaTUs (sp. nov.): caule erecto 2-pedali subglabro; ramis apice pubescentibus foliosis 
1-3-cephalis ; foliis plerisque alternis scabrido-pubescentibus ovato-lanceolatis vel oblongis triplinerviis lacini- 
ato-incisis dentatisve, superioribus basi lata sessilibus, inferioribus in petiolum marginatum attenuatis ; involu- 
cri squamis ovato-lanceolatis acutis inappendiculatis dense ciliatis discum fuscum subzequantibus ; ligulis cire. 
20 brevibus; paleis receptaculi apice deltoideo pubescentibus ; acheniis glabris biaristatis. — Valley of Nazas, 
Bolson de Mapimi, and west of San Lorenzo, Coahuila, Dr. Gregg ; May. — Leaves 2 or 3 inches long; the 
middle cauline especially bearing two or three lanceolate lobes on each side (a quarter or half an inch long), 
the others with as many coarse teeth. Heads two thirds of an inch in diameter. 
+ To the same genus, which, as Mr. Nuttall remarks, is distinguished from Helianthus chiefly by the total 
absence of a pappus, I am obliged to refer a low, shrubby plant of Dr. Gregg’s collection, viz. : — 
HELIOMERIS TENUIFOLIA (sp. nov.) : caule gracili 2— 3-pedali frutescente ramosissimo diffuso foliosissimo ; 
ramulis adscendentibus apice nudo pedunculiformi monocephalis ; foliis alternis vel suboppositis supra glabratis 
subtus incanis tripartitis vel 1—2-pedato-partitis segmentis lobisque anguste linearibus margine revolutis, sum- 
mis Sepe integerrimis ; involucri hemisphzrici squamis numerosis imbricatis e basi lanceolata lineari-appen- 
diculatis canescentibus ligulis cire. 15 dimidio brevioribus ; corollis disci flavis paleas naviculares obtusas su- 
perantibus ; receptaculo subconico ; acheniis cuneato-oblongis compresso-quadrangulatis glaberrimis calvis. — 
Dry valleys, at Rinconada, Saltillo, Mapimi, and Andabazo, Northern Mexico, Dr. Gregg ; May, June.—Called 
** Monacillo.”” Leaves ded 
, usually fascicled in the axils, from one to two inches in length, cleft into three 
entire divisions, the middle one prolonged, or each division again 2—5-parted ; the lobes and rachis only half 
a line wide. Involucre half an inch in diameter ; the exterior scales longest, rather shorter than the convex 
disk. Rays neutral. Corolla of the disk-flowers 5-nerved ; the tube more than half the length of the throat, 
puberulent, dilated at the base, where it fits over the apex of the achenium ; the lobes short, nearly smooth. 
Appendages of the style oblong, tipped with a minutely hispid cone. — Some specimens are less hoary than 
others, but there seems to be no farther difference. 
Dr. Gregg also collected Simsia auriculata, DC.? . Likewise a second species, the achenia of which are 
almost awnless, viz. :— 
SIMSIA sUBARISTATA (sp. nov.) : humilis, 
7 
strigoso-hispida ; caulibus ramisve adscendentibus apice nudo 
pedunculiformi monocephalis ; 
foliis hispido-incanis triangulari-ovatis serratis, superioribus hastato-trilobatis,
