tibus. — /3. compacte pulvinatum ; pedunculis brevissimis unifloris, 

 foliis subulatis creberrimis. — y. corapactum ; pedunculis foliis breviori- 

 bus 1 - 3-floris ; foliis latioribus lanceolato-subulatis ad margines angu- 

 losque acutissimos caulium crebrius spinuliferis. — California, Dr. 

 Andrews, Mr. Shelton (Herb. Torrey). Near Fort Tejon, Dr. Horn, 

 Dry Hills, Atascadero (var. a), and Santa Inez Mountains near Santa 

 Barbara (var. (S), near Kirka Pass (var. a), and near Monterey? (var. 

 •y), Dr. Brewer. — The laxer forms have the aspect of G. orientale, 

 the more condensed, of G. Pyrenaicum and G. Cyllenium, Boiss. ; 

 and the species is very different from any other North American one. 

 The Chilian G. hypnoides, Clos, is similar, but its leaves are nearly 

 destitute of costa, and it is said to have a distinct limb to the calyx. 

 The fruit apparently dry ; no involucre or whorl of bracts on the pe- 

 duncle. Plants from two inches to a span high. 



Galium Bloomeri: glaberrimum, inerme,* erecto-difFusum ; foliis 

 quaternis ovatis cuspidato-acuminatis subtrinerviis opacis, floralibus 

 SEepe tantum oppositis ; floribus abortu dioicis, masculis cymulosis 

 brevipedunculatis, foemineis subsolitaris subsessilibus ; corolla ut vide- 

 tur ochroleuca; fructu (juvenili) hirsutissimo. — Nevada Territory, 

 near Virginia City, Mr. H. G. Bloomer, to whom, as its discoverer, 

 and an ardent devotee to Botany, I have much pleasure in dedicating 

 this very well-marked species. The specimens are a foot or less in 

 height, from a perennial or suffrutescent base. Stems paniculately 

 branched. Leaves 3 to 5 lines long, closely sessile, rather rigid, vein- 

 less, the midrib evident, the larger leaves with a pair of lateral ribs, 

 which vanish near the middle. Corolla a line and a half in diameter. 

 The nature of the verticil is well shown in some of the floral leaves, 

 which are reduced to a pair, sometimes slightly connate by a transverse 

 membranous line, and sometimes with a smaller bifid or bidentate leaf 

 interposed on each side, this evidently answering to a connate pair of 

 stipules. 



Galium hypotrichium : humile, pube minuta cinerea scabridum, 

 inerme ; foliis quaternis ovatis apiculatis subtrinerviis, floralibus oppo- 

 sitis ; floribus submonoicis vel hermaphroditis parce cymulosis ; pedi- 

 cellis flore longioribus post anthesin recurvis ; fructu (juvenili) juxta 

 basin setis longis crinito, coeterum la^vi. — Sonora Pass, in the Sierra 

 Nevada, alt. 8,000 to 9,000 feet, in dry and rocky places. — A span 

 high, apparently tufted, in habit, foliage, «&c., much resembling the
