A peculiar genus of ten species, of the northern frigid regions, extending southward only along 

 high niountains, mainly Aniurican and Asiatic, two reaching high northern Europe, live North. 

 Auieiican.

 I'uur ranks, liiiek, sinuotli, not over '2 liin-s long, ovatu-ohlong, keulud on the buck : 

 peduncles lateral: corulla niodeiiitely 5-lobed : style rather slender. — Andromeda 

 Altrtensiana, liongard, Veg. yiteh. t. 5. A. cupressiiia, lluuk. Fl. ii. 38. 



In the Sierra Nevaihi, at or above 10,000 feet, from Mount Dana to I^assen's Teak {Bremer, 

 liolandcr, 4tc.) ; thenco to Alaska. Corolla 3 lines high and 4 broad. 



C. TErKAGONA, Don, which reaches Oregon and the Rocky Mountains, is very similar, except 

 that there is a deep groove down tho back of tlio leaf, and the {lower is rather smaller. 



7. BEYANTHUS, Steller, Gray. (Incl. Phyllodoce, Salisb.) 



Calyx of 5 or rarely 4 sepals, imbricated in the bud. Corolla campanulate and 

 more or less deei)ly lobed, or ovate, and I)arely 5-touthod ; tho lobes or teeth widely 

 spreading or recurved. .Stamens 10 or 8 (rarely fewer) : filaments filiform : antheis 

 opening by terminal oblique chinks. Style slender: stigma 5 - 4-lobed, or nearly 

 entire. Capsule globidar, septicidally 5 - 4-valved from the summit. — Dwarf ever- 

 greens ; ■with woody stems thickly beset with linear obtuse Heath-like leaves ; tho 

 llowers in a short raceme or umbel-like clubter from the summit of shoots of the pre- 

 ceding year, each pedicel from the axil of a firm foliaceous bract. — Gray, Proc. Am. 

 Acad. vii. 307. 



Consists of several arctic-aljiino species. Dr. Maximowicz, perhaps with sufficient reason, 

 •would retain thyllodoce und BriKvnthus, notwithstanding our li. llrewcri, on account of tho 

 •1-nicrous llowers, deeply parted condla, and naked exserted common peduncle of B. Gmelini. 

 ikil lliu new Caliiornian species dillera about oa much from tho true r/tijlloduccs as from tho 

 original Bri/iuUhiin, agreeing with tho latlur conspicuously in its deeply dolt corolla and long- 

 exserted stamens. 



On the other hand, I?iiitham nnd Hooker's flenera riantarum proposes to solve the didlculty 

 by cutting the knot, and the series, in the middle, referring to Brijanthus all the sjjecies with 

 open-campanulatc corolla, and only these : under tliis view both of the species known in California 

 would l)elong to Bri/aiU/nin, - -lo ui\ internii:<liate section, which may lie named PAitAimYANriUJS : 

 corolla open-campunulale, more or less ii-cleft or lobed : no common peduncle. 



1. B. BreTveri, Gray, 1. c. Stems rigid, ascending, a span to a foot high : 

 leaves snioutli ur nearly so (3 tu 7 lines long), narrowly linear, obtuse ; the margins 

 strongly revolnte : llowers at lirst as if umbellate, at length rather racemose : foli- 

 aceous bracts ovate or lanceolate : pedicels glamlular, soon longer than the flowers : 

 sepals glabrous : corolla rose-jjurple, almost saucer-shaped, 5-cleft fully to the mid- 

 dle : stamens (7 to 10) and style much exserted. 



High and rocky summits in tho Sierra Nevada, at 10,000 feet und upwards, from Mariposa to 

 Sierra C^o., Brewer, Turrcy, Bolander, &c. The handsomest species of the genus. 



2. B. empetriformis, (^ray, 1. c. A span or so in height, more branched than 

 tho precetling : umhcilatc llowtns much smaller : corulla (liardly over 2 lincis long) 

 rose-color, campanulate; its lobes nnich shorter than the tube: stamens iiududed : 

 style sometimes exserted. — Mciiziesia einpdri/ormis, Smith; (Jraham in Hot. Mug.

Rocks on Mount Shasta, at 8,000 feet and higher, Brewer. Also high northward and in the 

 Rocky Alountains.
