26. R. Nuttallii, Booth-, Nutt. in Hook. Kew Journ. v. (1853) 355; 

 leaves elliptic base rounded glabrous, pedicels 2-5 clustered calyx-lobes oblong- 

 oval obtuse, corolla very large white. Hook. Bot. Mag. t. 5146 ; Fl. des Serres, 

 xiii. (1868) t. 1326 ; Illustr. Sortie. (1859) t. 208. 



BHOTAN ; Duphla Hills, alt. 4-5000 ft., Booth. 



A tree, 30 feet; or a straggling epiphyte. Leaves 8 by 4 in., obtuse, coriaceous, 

 rugose by impressed nerves above ; petiole |- in. Pedicels 1-2 in., exceedingly thick in 

 fruit. Calyx-lobes f by in., glabrous or slightly ciliated, rose-coloured. Corolla

 5, subentire. Stamens 10; filaments hairy below. Ovary 5-celled, scaly-glandular. 

 Capsule If by | in., straight, glabrescent. Seeds oblong, compressed, widely mar- 

 gined; testa close. Nuttall says that the calyx, caps-ule and seeds in this species 

 are wholly different from those of E. DalhousicB ; but there appears little difference 

 except in size.

 rhomboid-elliptic acuminate ciliate and villose on the margin, corymbs dense

 (fide Illustr. Hortic.}. Capsule ^ by 5 in., rugose, furfuraceous. Seeds linear, com-

SIKKIM HIMALAYA; Lachen, alt. 9000 ft., J. D. H.; Chola and Dikchoo, alt. 

 9-10,000 ft., Clarke. 



A shrub, 2-4 ft., often spread over rocks. Leaves 2| by 1^ in., base obtuse or 

 rounded, glabrous beneath or midrib bristly ; petiole \ in. Pedicels \-% in. ; bracts 

 ovate, glabrous. Calyx-lobes by \ in., glabious, ciliate. Corolla \~ in. ; lobes 5, 

 emarginate. Stamens 10. Ovary 5-celled, scaly-glandular. Capsule \ by \-\ in., 

 scaly. Seeds linear ; testa close, crested at one end. The wild plant has the flowers 

 white, slightly tinged with rose, fading a deeper rose. Sir J. D. Hooker sketched 

 his species in Sikkim (Rhod. Sikkim, t. 24) from a plant "past flower;" hence with 

 too purple a corolla.

 oblong or elliptic glabrous densely ferruginous scaly beneath, pedicels 1-4-nate, 

 calyx-lobes elliptic obtuse, corolla white tube cylindric lobes widely spreading.
