 persistent ; tin; limb hemisi)1ierical-campanulate, 5-l(ibeil, deciduous : esti- 

 vation valvate ? Petals none. Stamens 15-25, inserted in 2-3 series on 

 the limb of ilic calyx: filaments short : anthers oval or roundish, deeply 

 emargiiiate or cleft at each end, often pubescent. Ovary solitary, free, with 

 a simple erect ovule : style terminal, filiform, villous : stigma obtuse. Ache- 

 nium linear-oblong, coriaceous (membranaceous, Kuntli.), caudate with tlie 

 long persistent plumose stj'le, which is more or less included in the slender 

 persistent tube of the calyx. Seed linear, witli a membranous testa, desti-

 Leaves alternate, straight-veined, coriaceous, serrate or entire, on short pe- 

 tioles. Stii)ules wholly adnate to the base of the petiole. Flowers axillary 

 or terminating short leafy branches, sessile, or on short pedicels, mostly 

 fascicled. 



-r^l. C. j)arvifoUiis (l^uH.l riiss.) : leaves cuneiform-obovate, silky-pubcs- 

 'cent or at length nearly glabrous above, tomentose-canescent beneath, coarse- 

 ly toothed towards the apex ; flowers solitary or in pairs, on short pedicels, 

 recurved ; tail of the fruit very long, densely ])luniose. — Hook. S^' Arn. ! bot.

Rocky Mountains, in busliy ravines near the sources of the IMatte, Dr. 

 James ! Nuflall ! California, Douglas ! .June. — A low shnib. Leaves 

 scarcely an inch in length, much smaller and less coriaceous than the C. 

 fothergilloides, which has numerous erect sessile flowers, fascicled in the 

 axils, &c. 



2. C. hctidoides (Nutr. ! mss.) : " somewhat glabrous ; lea\'cs broadly obo- 

 .vate, shining and nearly glabrous above, jjubescent on the (not very promin- 

 ent) \'eins beneath, serrate-toothed towards the a])ex ; flowers 2-6 in a fasci- 

 cle, on short pedicels, recurA^d ; fruit unknown." — Hook. ! ic. j^l- (• 323.

" Mountains of St. Barbara, California ! Ajiril. — " A shrub, with the 

 leaves about twice as large as the ])receding, to which it is allied, resembling 

 those of Alims serrulata, but smaller." Nitftall. — We much doubt if this be 

 sufficiently distinct from tlie foregoing species, of which our specimen in 

 fruit, from Douglas's collection, has tlie leaves almost as large and nearly as 

 smooth. 



3. C. ledifolius (Nutt. ! mss.) : leaves lanceolate, entire, veinless, revolute, 

 at length nearly glabrous above, tomcntose beneath, much crowded on the 

 short flowering branches ; flowers erect, sessile, 2-3 in a fascicle ; tail of the 

 fruit very long and tortuous. — Hook.! ic. p>l. t. 324. {ined.) 



" Rocky Mountains, in al])ine situations on the summits of the hills of Bear 

 River of Timpanagos, near the celebrated " 2feer K^^mwfis," which abound 

 with carbonic acid. A sliridj, or small tree, G-10 feet high, with wliite 

 tough wood; the branches gray, terete, covered with circular cicatrizations. 

 Leaves resembling those of Ledum latifolium, very coriaceous, on ^■e^y short 

 petioles. Stamens and inner surface olllie flowers smooth. Tlic aclicniuni, 

 which with its tortuose and plumose tail almost exactly rescml)les the fruit 

 of some species of Stipa, is coriaceous, and 2-seeded. Testa of the seed
