7. DIPLARCHE, H.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 ; 5 alternate basal or hypogynous ; 

 anthers elliptic, dehiscing longitudinally. Ovary 5-celled ; style short, stigma 

 capitate 5-lobed ; ovules numerous in each cell. Capsule globose, enclosed by the 

 calyx, 5-celled, septicidally 6-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 lax tissue. Species 2, Himalayan. 



1. D. xnultiflora, H.f. $ T. in Hook. Kew Journ. vi. (1854) 383, t. 11, 

 fig. A ; branches glandular-pubescent, flowers many densely capitate, sepals 

 linear-oblong subacute, lower 5 stamens attached to the corolla.

Leaves \ by ~ in. Flowers 8-20 forming a globose head in. diam. Peduncle 

 in fruit elongate, pubescent ; capsules in. diam., spicate. 



2. D. pauciflora, H. f. $ T. in Hook. Kew Journ. vi. (1854) 383, t. 11, 

 fig. B ; branches glabrous or nearly so, flowers terminal few, sepals ovate-oblong

Closely resembling D. multiftora, but smaller in all its parts. Leaves -| in. 

 Flowers 2-6 at the apex of the branc-h. 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 cylindric, 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 loose, often shortly 

 crested, or tailed at one or both ends. Species 130, in the Mts. of Europe, 

 Asia, Malaya and N. America. 



STJBGENTTS I. Vireya (Gen. Blume Bijd. 854). Capsule elongate, acute; 

 valves twisting after dehiscence, not woody ; placentae 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. 

 1. R. malayanum, Ja<ik in Mai. Misc. ii. n. 7, 17 ; leaves lanceolate 

 acute glabrous glandular-scaly beneath, corolla red, tube cylindric twice as long
