﻿90 PLANTS FENDLERIAN.S. 



oblongis apice truncato-erosis enerviis, coronata. — Herba annua, glabra, grosse glandu- 

 losa, Dysodiae chrysanthemoidis facie, sed foliis plerisque alternis atque ligulis aureis con- 

 spicuis. — Genus inter Dysodiam et Tagetem referendum, ab utrisque pappo parvo sim- 

 pliciter et aequaliter squamellato plane diversum, dicavi in memoriam Hon. Jobannis 

 Lowell, qui non solum res georgicas sed etiam berbarias in Nova Anglia magnopere 

 promovebat, in honoremque filii Jobannis-Amory Lowell, de botanice bene meriti, itineris 

 Fendleriani fautoris. 



which well accords with the description, except that only from three to five of the paleoe of the pappus are 

 awned, and which I consider as only a variety of the species referred below to H. pentacha?tum. 

 •^ H. Beelandieri, DC. I. c. If Berlandier's plant, gathered between Santander and Vittoria, Mexico, is 

 the same as Hartweg's no. 129, from Aguas Calientes in the south of Zacatecas (which alone I have seen), 

 the species is well distinguished from the next by the more upright growth, the longer lobes of the leaves (the 

 terminal an inch or more in length), and the smaller, fewer-flowered involucre, which is hardly two lines long, 

 cylindraceous, and with the strictly uniseriate scales united to the top. The pappus has five of the scales 

 much shorter than the others, oblong, truncate or very obtuse, and unawned ; the five alternate ones oblong- 

 lanceolate, bearing two short, more or less cuspidate or setigerous teeth at the apex, and between them pro- 

 duced into a slender and scabrous awn, a little shorter than the corolla. 



H. fentach^tu.m, DC. I. c. Of this it is said : " Facile cum H. Berlandieri et tenuilobo prima fronte 

 confundendum, sed pappo 5- nee 10-setoso distinctum." The plant was gathered at Monterey, Mexico, by 

 Berlandier. From the same locality (Monterey, near the Bishop's palace, &c), as well as from the " high- 

 lands around Saltillo and Buena Vista," Dr. Gregg abundantly collected specimens which well accord with 

 the character of this species, except that they all exhibit the five shorter and erosely truncate paleee of the pap- 

 pus, just as in the preceding. A specimen gathered at Monterey by Dr. Edwards exhibits the same charac- 

 ters ; as also do those of Dr. Wislizenus, gathered farther west, between San Juan and Vequeria. I cannot 

 but conclude that these shorter palea: of the pappus were overlooked by De Candolle. The rigid, Heath-like 

 foliage is densely crowded on the diffuse and tufted branches, and cinereous-pubescent : the naked peduncles 

 are 2 inches long, and bear a few minute and scattered setaceous bracts : the campanulate or broadly turbinate 

 involucre is three lines long, cinereous-puberulent ; with the scales evidently biseriate, and distinct or separa- 

 ble, the exterior especially, for a fourth part or nearly half their length. The five awns of the pappus are 

 nearly as long as the disk-corolla. — A Texan specimen, mentioned above, from Eagle Pass, on the Rio 

 Grande, has one or two of the larger palea? unawned and pointless, and has merely glabrous leaves : but I see 

 no other distinction. 



* * Floccoso-lanata : folia integra spalhulata : pedunculi fere nuUi. 



H. gnaphalodes (sp. nov.) : nana, undique albo-lanatissima ; caulibus e radice annua ? ramosis depressis 

 proliferis ; foliis plerisque alternis spathulatis integerrimis vel apice rotundato subdentatis confertis ad innova- 

 tiones imbricatis ; capitulis brevissime pedunculatis vel intra folia sessilibus ; involucri 1 - 3-bracteati squamis 

 uniseriatis connatis ; ligulis 10- 13 ovalibus exsertis ; pappi paleis 5 majoribus lanceolatis alternas eroso-trun- 

 catas triplo superantibus apice in subulas 2 membranaceas et aristam mediam corollam disci subrequantem 

 trifidis. — On Bishop's Hill, Monterey, February, Dr. Gregg. Called " Lipillana.' 1 '' — Plant with much the 

 aspect of Filaginopsis, Torr. $• Gray, or of Diaperia, Null. ; the rigid, but apparently annual, tufted stems
