 oblong, glabrous, membranous. Corolla 3-4 in.; lobes 5, rounded. Stamens 18;

 linear-lanceolate, caudate, large for the genus; testa close, produced at the ends.

 The capsules in Griffith's and Booth's (numerous) examples hardly average one half 

 the size of those of H. Maddeni ; the largest capsule in R. calophylla is hardly f by 

 ^ in., and its calyx-lobes are not at all enlarged in fruit. The leaves in the two 

 varieties (or species?) are exactly alike.

BHOTAN ; Griffith, Booth. KHASIA MTS, ; alt. 3-5000 ft., common. MARTABAN ; 

 Nattoung, alt. 7200 ft., Kurz. 



A shrub, 8 ft. ; branchlets glabrous, rarely ferruginous-bristly. Leaves l-2i in., 

 variable in size, usually broadest above the middle, shortly acute, long attenuate to 

 the base, glands beneath numerous (but not approximate as in R. Maddeni) ; petiole 

 -^ in. Pedicels \ in., glandular-scaly; bracts \ in., ovate, glabrous, ciliate. Calyx- 

 lobes obtuse, hirsute or glabrous. Corolla 1^-2 in. long and broad ; lobes about as 

 long as the tube, round, entire or slightly crenate, sometimes with pink marks. 

 Stamens 10; filaments sparsely pilose. Ovary 5-celled, scaly. Capsule f by ^ in., 

 erect, symmetric. Seeds elliptic, acute; testa close, hardly produced at the ends. 



VAR. salicifolia ; leaves very narrowly lanceolate, sometimes 3 by less than ^ in. 

 Khasia, frequent. 



VAR. in^ialis ; capsule f by ^ in., ovoid, unsymmetric from a very unequal base. 

 Khasia ; Kollong rock, alt. 5000 ft., H. f. $ 2\ This has been considered a dis-

 setose ; leaves entirely without the setose ciliee common (but sometimes wanting) in 

 R. formosum. Capsules (of which there are numerous examples) more unsymmetric 

 than in any other Indian Rhododendron,

 hirsute. Leaves 3^ by l-l in., base cuneate; petiole \ in., sometimes hirsute. 

 Umbels terminal, 3-8- flowered ; pedicels \ in., glandular-tcaly ; bracts 1 by ^ in., 

 acute, villous below. Calyx-lobes small, unequal, sometimes hirsute. Corolla 2-2 

 in. long, and broad, glandular-scaly without or nearly glabrous; lobes 5, round, 

 crisped-crenulate. Stamens 12-14; filaments hairy below. Ovary and base of the 

 style densely glandular-scaly ; stigma large, peltate. Capsule not seen. This hardly
