goats in the interior of the island, conspicuous by its very white foliage 

 and abundant golden-yellow blossonas. A remarkable and anomalous 

 species, but certainly of this genus, having all the characters. One of 

 the genuine species already published is ray less. In size (probably 

 2 or 3 feet high), in the dense tomentum, and in the naked dense 

 corymbs or cymes, this is peculiar. The squamelliB . of the pappus 

 are as long as the breadth of the akene. 



^ Hemizonia (Uartjiannia) fkutescens. Fruticosa, erecta, ultra 

 bipedalis, hirsutula, subviscida ; ramis Horidis virgatis fastigiatis folio- 

 sissimis ; foliis iiliformibus (pollicaribus, fasciculorum brevioribus) 

 integerrimis raro 1-3-lobatis ; capitulis thyrsoideo-racemosis (lin. 3 

 altis) ; ligulis 8-9 aureis obovato-oblongis 2-3-dentatis involucro glabri- 

 usculo. ajquilongis ; disci floribus 10-12 receptaculi convexi paleis 

 totidem linearibus fere discretis circumdatis ; pnppo e paleis 5 lineari- 

 bus vel subulatis fimbriato-denticulatis. — Rocky precipices in the 

 interior of Guadalupe Island, otF Lower California, Dr. E. Palmer. 

 Disk-akenes well-formed, but apparently sterile. This and the fol- 

 lowing are striking additions to the Hurlmannia section of the genus. 



^ Hemizonia (Hartmannia) floribunda. Erecta. glanduloso- 

 pubescens, forte tripedalis (basi ignota) ; ramis crebris foliosissimis ; 

 foliis linearibus obtusis integerrimis (|-|-pollicaribus) ; capitulis raniu- 

 los terminantibus paniculatis (lin. 3-4 altis); involucro creberrime 

 glanduloso disco breviore ; ligulis plus 20 mnjusculis biseriatis cuneatis 

 apice 3-lobatis aurantiacis ; fl. disci totidem ; receptaculo paruin con- 

 vt'xo inter discum et radium paleis linearibus discretis onusto; aclieniis 

 disci plerumque fertilibus pappo e paleis 5-8 late ovatis obtusissimis 

 integerrimis dorso margineque hirsutulis coronatis. — California, near 

 the southern boundary, on the ¥ovi Yuma Road, 80 miles east of 

 San Diego, Dr. E. Palmer. Belongs to the subdivision which includes 

 H. angustifolia and H. curymbosa. 



^ Artemisia Palmeri. (Sen'plu'dinm, licet receptaculum paleis 

 onustum.) Ut videtur elata et herbacea, cinereo-puberula ; foliis 3-5- 

 partitis, ramealibus integerrimis lobisque augusto-linearibus elongatis 

 subtus tomentoso-incanis margine revolutis ; panicula amplissima flori- 

 bunda ; involuL-ri squamis ovatis subscarioso-membranaceis ; aclieniis 

 immaturis disco epigyno majusculo. — San Diego County, California, 

 In Jamuel Valley, 20 miles below San Diego, Dr. E. Palmer. Habit 

 nearly of A. Calif arnica, but apparently herbaceous throughout, and
