goats in the interior of the ishuul, couspiciious by its very white fohage 

 and abuiulaiit golden-yellow blossoms. A remarkable and anomalous 

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

 the genuine species already published is rayless. In size (probably 

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

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

 are as long as the breadth of the akene. 



IIkmizoxia (Hartmanxia) fkctkscexs. Fruticosa, erecta, ultra 

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

 sissimis ; foliis liliformibus (poliicaribus, fasciculorum brevioribus) 

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

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

 usculo a?quilongis; disci floribus 10-12 receptaculi convexi paleis 

 totitlem liuearibus fere discretis circumdatis ; pappo e paleis 5 lineari- 

 bus vel subulatis finibriato-deiiticulatis. — Rocky precipices in the 

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

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

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



Hemizoxia (Hart-MAXXIa) floribcnda. Erecta, glanduloso- 

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

 foliis liuearibus obtusis integerrimis (^-^-poliicaribus) ; capitulis ramu- 

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

 glanduloso disco breviore ; ligulis plus 20 majusculis biseriatis cuneatis 

 apice o-lobatis aurautiacis ; H. disci totidem ; receptaculo parum con- 

 vexo inter disoum et radium paleis linearibus discretis onusto ; acheniis 

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

 integerrimis dorso margineque hirsutulis coronatis. — California, near 

 the southern boundary, on the Fort Yuma Road, 80 miles east of 

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

 J{. anguslifoUa and H. cui-ymbosa. 



Artemisia Palmeri. (^Serlphidium, licet recei)taculum paleis 

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

 partitis, ramealibus integerrimis lobisque angusto-linearibus elongatis 

 subtus tomentoso-incanis margine revolutis ; panicula amplissima flori- 

 buiida ; involucri squamis ovatis subscarioso-membranaceis ; acheniis 

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

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

 nearly of A. Gcdifornica, but apparently herbaceous througliout. and 

 with the leaves or lobes broader and flat, a line or more in diameter.
