Rhododendron. ERICACEAE. 39 



K. hirsiita, "Walt. About a foot high, branching freely : leaves nearly sessile, plane, 

 oblong or lanceolate, a quarter to half inch long : flowers scattered and axillary, produced 

 through the summer, on pedicels longer than the leaves : sepals ovate-lanceolate and leaf- 

 like, as long as the rose-purple corolla (this barely half inch in diameter), at length decidu- 

 ous, leaving the old capsules bare. — Bot. Mag. t. 138. K. ciliala, Bartram, Trav. — Low 



. pine barrens, S. E. Virginia to Florida. 



16. MENZI]^SIA, Smith. (Archibald Menzies, assistant surgeon in Van- 

 couver's voyage, 1791-95, brought the original species from the N. W. coast.) — 

 Deciduous-leaved shrubs, of N. Am. and Japan ; with the foliage of the Azaleas, 

 but vfith small and mostly dull-colored 4-merous flowers (the corolla barely lobed, 

 in ours a quarter inch long, lurid-purplish), developed at the same time as the 

 leaves, from separate strobilaceous buds, which terminate the branches of the 

 preceding year ; the pedicels nodding in flower, erect in fruit. Leaves alternate, 

 membranaceous, glandular-mucronate. Capsule short: placentas attached to the 

 whole length of the columella. Flowers in early summer. — Smith, Ic. PL 59 ; 

 Salisb. Parad. Lond. 44 ; Maxim. Rhod. As. Or. 7. 



* Seeds with tail or appendage at each end as long as the nucleus: capsule smooth and naked or 

 nearly so, inclined to obovate : filaments more or less ciliate below. 



M. glabella. Strigose-chaffy scales wanting, or very few on young petioles and midrib 

 beneath : leaves obovate, mostly obtuse, barely mucronate-tipped, glaucescent and glabrous 

 or nearly so beneath (an incli or two long), sprinkled with some small appressed hairs 

 above, the obscurely serrulate margins minutely ciliolate: pedicels naked or somewhat 

 glandular: corolla ovoid-campanulate. — -.1/. globularis, Hook. Fl. ii. 41 ; Maxini. Rliod. As. 

 Or. 1. c, not Salisb. M. fei-ruginea, Gray in Proc. Am. Acad. viii. 393.— Rocky Mountains, 

 lat. 49°-56° (Drummond, Bourgeau), thence to Washington Territory and Oregon, Li/all, 

 Tolmie, E. Hall. 



* # Seeds merely apiculate or very short-tailed : capsule ovate : filaments glabrous. 



M. globularis, Salisb. Straggling or loosely branched shrub 2 to 5 feet high (like the 

 others), more or less chaffy : leaves obovate-oblong, usually obtuse, prominently glandular- 

 mucronate, strigose-hirsute especially above, glaucescent beneath : pedicels glandular : 

 corolla globular-ovate becoming ovate-campanulate : capsule beset with short gland-tipped 

 bristles. — Pursh, 1. c. M. Smithii, Michx. Fl. i. 235. M. ferruginea, var. (globularis), Sims, 

 Bot. Mag. t. 1571 ; Gray, Man. ed. 2 & 3. M. pilosa, Juss. in Ann. Mus. i. 56. Azalea pilosa, 

 Michx. in Lam. Jour. Nat. Hist. i. 410. — Woods, through the Alleghany Mountains, from 

 Pennsylvania to Georgia. Most like the preceding, but the seeds very different ; the small 

 calyx commonly more distinctly 44obed. Leaves an inch or two long. 



M. ferruginea, Smith. Strigose-chaff not rare on young parts : leaves oblong or lan- 

 ■ceolate-obovate, acute or acutish at both ends, prominently glandular-mucronate, more 

 ciliate with glandular bristles, rusty strigose-hirsute above, merely paler beneath (somewhat 

 blackening in drying) : pedicels bristly-glandular : corolla oblong-ovate and becoming 

 cylindraceous. — Pursh, Fl. i. 264 ; Hook. 1. c. ; Maxim. 1. c. — Woods, coast of Oregon 

 to Alaska and Aleutian Islands. (Kamtschatka ■») 



17. RHODODENDRON, L. Rose Bay, Azalea, &c. (The ancient 

 Greek name, meaning rose-tree.) — Shrubs or small trees, of diverse habit 

 and character, with chiefly alternate entire leaves : the principal divisions have 

 been received as genera, but they all run together. Only five are N. American 

 out of the eight subgenera of Maximowicz, Rhod. As. Or. 13. (Rhododendron & 

 Azalea, L.) — The first two subgenera are very anomalous. 



• §1. TherorHodion, Maxim. Flowers one or two terminating leafy shoots 

 of the season ; the thin bud-scales of the shoot deciduous only with the annual 

 leaves: corolla- rotate, divided to the base on the lower side : stamens 10.
