ASSAM AND BOOTAN. 357 
have been found by Griffiths in Bootan, according to a bad specimen 
in seed in the herbarium of Sir William Hooker. 
This species forms a second section, having a distinctly lobed stigma 
and a six-celled capsule. 
$ CALODENDRON.—Stigma filiform. Ovary six- to ten-celled. Calyx 
usually minute. ` Mostly trees or large shrubs, with the flowers in 
dense corymbs. 
8. RHODODENDRON WINDSORII, Nutt. 
Arboreum : foliis coriaceis, obovato-lanceolatis, acutis, in petiolum at- 
tenuatis, glabris, subtus argenteis, demum rufescentibus; capitulis 
multifloris, bracteis sericeis; calycis lobis brevissimis; corolla puni- 
cea, lobis emarginatis; staminibus 10; capsulis cylindraceo-oblon- 
gis glabris 10-locularibus ; seminibus lanceolatis subulatis. 
Han. In the mountains of Bootan, growing at an elevation of 7-9000 
feet above the sea, on the ridges and slopes of Roophrye, in exposed 
and arid situations, with Pines, species of Cupressus, Berberis, etc. 
Becoming a small tree, with coriaceous leaves, obovate-lanceolate 
and acute, 4-5 inches long, 1-14 broad, strongly reticulated, and pin- 
nately nerved, shining-white and silvery beneath, at length pale brown. 
Heads many-flowered, crowded; the bracts dilated and silky; lobes 
of the corolla all emarginate, the colour a deep crimson-scarlet, rather 
deeper-coloured than in R. arboreum, to which this species is nearly 
related. It is more particularly allied to R. roseum of the gardens, but 
different in the foliage and colour of the flower. The calyx is minute; 
stamens 10. Capsule at length smooth, oblique at base, ten-celled. 
An abundant and very variable species; the leayes sometimes lu- 
cidly shining; in other individuals dull, or clothed more or less with 
golden yellow pulverulent deciduous down : in form also varying from o 
almost obovate to lanceolate or elliptic-lanceolate. 
B. leucanthum ; foliis elliptico-lanceolatis opacis, floribus albis. — — 
` "This variety, or almost species, is readily distinguished by its more - 
lanceolate leaves, of an opake dull green above, but, like the former, 
beneath, passing at length from a silvery-white to a pale brown; the 
flowers are also constantly white. 
Both these varieties appear to be hardy in this part of England ——— 
(Lancashire); as a plant of the former stood out all the last winter, - Se 
though but a small seedling. unt
