7. DIPLA RCHE, M.f. $ T. 
Small low shrubs. Leaves small, sessile, crowded, linear-oblong, coriaceous, 
serrate or long-ciliate, subacute or ending in a gland. Flowers small, rose- 
coloured, subcapitate, terminal; bract ciliate, ovate; bracteoles lateral, linear, 
shorter than the sepals. Sepals 5, coriaceous, ciliate. Corolla deciduous; tube 
cylindric ; lobes 5, obovate, patent. Stamens 10, included ; 5 inserted high on 
the corolla, alternate with its lobes; 6 alternate basal or hypogynous ; 
anthers elliptic, dehiscing longitudinally. Ovary 5-celled ; style short, stigma 
eg 5-lobed ; ovules numerous in each cell. Capsule globose, enclosed by the 
calyx, 5-celled, septicidally 5-valved ; the wall of the cells splitting into two 
layers, the outer of which breaks up in appearance loculicidally. Seeds very 
many, obovate-cuneate, compressed ; testa of tes tissue.—Species 2, Himalayan.

Closely resembling D. multiflora, but smaller in all its parts. Leaves d-l in. 
` Flowers 2-6 at the apex of the branch. Stamens of the lower series often left sur- 
rounding the capsule after the corolla has fallen. 
8 RHODODENDRON, Linn. 
Trees or shrubs, sometimes very small; often scaly or aromatic. Leaves 
alternate, often clustered towards the ends of the branches, rarely subopposite 
or falsely whorled, entire, coriaceous. Flowers fascicled or subcorymbose, 
terminal, rarely solitary or axillary ; bracts broad, generally caducous ; bracteoles 
linear. Calyx 5-lobed, sometimes small or obsolete, rarely saucer-shaped, per- 
sistent. Corolla campanulate, widely funnel-shaped or ius tz tube long or 
short, lobes 5-10. Stamens 5-18, usually 10; anthers oblong, dehiscing by 
terminal pores. Ovary 5-20-celled ; style long or short, stigma capitate ; ovules 
very many in each cell. Capsule short woody, or elongate thinner, 4-20-celled, 
septicidally 4-20-valved from the apex, valves breaking away from the placentas. 
Seeds very many, ellipsoid, albuminous; testa close or in often shortly 
crested, or tailed at one or both ends.—Species 130, in the Mts. of Europe, 
Asia, Malaya and N. America. 
SuBGENUS I. Vireya (Gen. Blume Bijd. 854). Capsule elongate, acute ; 
valves twisting after dehiscence, not woody; placente separating (leaving a 
slender central axis) as five filiform ribs, attached at the apex. Seeds very long- 
tailed at both ends, the tails many times longer than the seed.—Malayan 
large shrubs ; leaves subopposite or almost whorled ; flowers in sessile terminal 
umbels; bracts caducous; exocarp often separating from the endocarp, dehiscing 
irregularly or somewhat loculicidally. 
* Leaves sprinkled beneath with sessile round glandular scales.
