﻿84 PLANTS FENDLERUNjE. 



f395. H. tracheliifolius, Willd. ; Ton: & Gray, I. c. Creek bottom, 30 miles 

 east of Council Grove ; Aug.* (431.) 



f396. Heliomeris multiflora, 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.! (This is 

 probably the plant enumerated asWulfia? 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 Alrorubentes, viz. : — 



•/ Helianthus laciniatus (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 subrequantibus ; ligulis circ. 

 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. 



t 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-pedaIi 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 scepe integerrimis ; involucri hemisphsrici squamis numerosis imbricatis e basi lanceolata lineari-appen- 

 diculatis canescentibus ligulis circ. 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 crowded, 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. 1 Likewise a second species, the achenia of which are 

 almost awnless, viz. : — 

 / Simsia subaristata (sp. nov.): humilis, strigoso-hispida ; caulibus ramisve adscendentibus apice nudo 

 pedunculiformi monocephalis; foliis hispido-incanis triangulari-ovatis serratis, superioribus hastato-trilobatis,
