carpia compressa sursum sensim quinquealata ; alis suberosis, margi- 

 nalibus latioribus ; valleculis univittatis ; commissura bivittata. Carpo- 

 phorum bipartitum. Semen more Cymopteri sectione transvera plani- 

 usculo-lunata. — Herba Californica ; radice fusiforrai ; caule valido 

 fistuloso usque ad urabellas cum foliis sub-bipinnatisectis glabro ; ura- 

 bellis tomentosis exinvolucratis ; involucellis multipartitis flores albos 

 sessiles densissime capitatos subtequantibus. 



Sphenosciadium capitellatum. — In the Sierra Nevada, near 

 Ebbett's Pass, alt. 7 - 8,000 feet, by a stream ; in flower. Nevada, 

 near Carson City, Dr. C. L. Anderson ; with fruit. Root rather 

 strong-scented, acrid. Stem 2 to 5 feet high, sti'iate. Petioles spatha- 

 ceous-dilated. Divisions of the leaves ovate- or oblong-lanceolate, 

 about an inch long, coarsely and sharply few-toothed or incised ; veinlets 

 finely reticulated. Umbel 7 - 10-radiate ; the umbellets are globose 

 heads, 4 or 5 lines in diameter, in fruit about three fourths of an inch ; 

 the flowers (pubescent) sessile on a dilated receptacle, to which the 

 short involucel is somewhat adnate. Fruits 3 lines long, pubescent ; 

 the mericarps (including the wings) obovate-cuneate or obscurely ob- 

 cordate ; the narrow base strongly o-ribbed ; but the corky ribs en- 

 large towards or at the summit into thickish wings, the lateral ones 

 being the broadest, sometimes nearly as broad as the seed. A thick 

 vitta in each interval, and two submarginal ones on the commissure. 



LoNiCERA (Xylosteon) Breweri : caule erecto ; foliis ovalibus 

 vel obovatis pubescentibus breviter petiolatis ; pedunculis folio sublon- 

 gioribus ; ovariis urceolato-oblongis basi coadnuatis ; bracteolis mini- 

 mis ; corolla lurido-purpurea campanulata late gibbosa ultra medium 

 bilabiata ; faucs styloque hirsutissimis. — In a ravine of the Sierra 

 Nevada, near Mount Dana, at the elevation of about 10,000 feet. — 

 Allied to L. nigra of the Old World ; but the leaves (only an inch or 

 less in length) rounder, much more pubescent, and of a different vena- 

 tion ; the ovaries narrower, and crowned with subulate calyx-teeth, the 

 corolla more gibbous, the style hirsute, &;c. 



Galium Andre'WSii: pulvinato-csespitosum ; rhizomatibus longis fili- 

 formibus ; foliis crebris quaternis subulatis setuloso-apiculatis rigidis 

 nitidulis glabris aut fere nudis aut cum angulis caulium pi. m. spinuloso- 

 ciliatis, costa valida ; pedunculis 1 - S-floris nudis ; floribus albidis ; 

 fructu laevi. — Var. a. gracilius ; foliis lineari- vel aciculari-subulatis 

 margine aut parce aut rarissime spinuliferis : pedunculis folia adagquan-
