ceo-scariosis obovato-cuneatis cucullatis glabris achenio pyriformi in- 

 volventibus. — Shady places in the mountains above Batopilas, Pa/mer, 

 164. Character wholly from Dr. Palmer's specimens, in flower, and 

 also some in fruit. But the species may probably include the plant 

 collected by Seemann in the Sierra Madre of Durango, referred by 

 Schultz Bip., Bot. Herald, 304, to his Montagnea atriplicifolia. Our 

 specimen of this is incomplete, and it has larger ligules. Schultz was 

 probably right in identifying Verbesina atriplicifolia, Juss., DC, and 

 Colla, Hort. Rip. 144, t. 31, with M. arborescens, DC, but surely he is 

 not to be followed in the making of a new name for it on account of 

 this identification. A comparison with Colla's description and figure 

 of M. arborescens (under the above-mentioned name) makes it clear 

 that to this may be referred the 3f. grandiflora, Benth. PI. Hartw. no. 

 134 (not of DC), a species which comes nearest to 31. frutescens* 



Helianthella Pringlei. Species singularis, hispidulo-scabrella ; 

 caulibus e caudice lignescente pluribus ultra-pedalibus ad apicem usque 

 a^qualiter foliosis ; foliis ellipticis (circ. bipollicaribus siccitate charta- 

 ceis nitidulis) uninerviis venulosis basi parum angustata sessilibus ; 

 capitulo sat pedunculato ultra-semipoUicari ; involucro fere glabro, 

 bracteis subulato-liiiearibus laxis, iis receptaculi chartaceis obtusis ; 

 ligulis lin. 7-8 longis linearibus ; acheniis immaturis lineari-oblongis 

 (extimis nunc 3-4-gonis) cano-villosis breviter biaristatis ; squamellis 

 intermediis ant nullis aut inter pilos achenii evanidis. — On rocky 

 hills west of Chihuahua, Sept., Pringle, 646. 



Verbesina Ciiihuahuensis. V. Wrightii, Gray soror, gracilior, 

 magis ramosa ; foliis plerisque in petiolum attenuatis, aut omnibus 

 lanceolatis dentato-incisis rariusve subintegerrimis alternis, aut inferi- 

 oribus oppositis latioribus basi abruptis ; capitulis parvulis (lin. 4 altis) ; 

 involucro brevi laxiore ; acheniis hirsutulis plerumque longiuscule 

 biaristatis. — Santa Eulalia Mountains, near Chihuahua, on limestone, 

 in cafions, Pringle, 657. 



Verbesina leptoch^ta. Inter Pterophyta aptera, V. Wrightii 

 parum similis, frutescens ; foliis oppositis serratis hispidulo-scabris 

 tri[)linerviis, caulinis deltoideis (4-5-pollicaribus), ramealibus ovato- 

 lanceolatis, omnibus in petiolum alato-marginatum subito decurrenti- 

 bus ; capitulis subsolitariis pedunculatis majusculis (ultra-semipolli- 



* No. 535, Ghicsbreglit, Chiapas, coll. 1864-70, referred to M. arborescens 

 by Hemsley, probably through my wrong naming of a specimen sent fropi 

 this herbarium to that of Kew, is a very different species; but before naming 

 it one should compare the several species of Schultz published by Koch in 

 Wochenschr. vii., here unknown.
