RHODODENDRON DALHOUSIE, Hook. fil. Jalapahar, с. 7400’, 13. iv. (15667). 
GRANDE, light. Senchal, с. 8500’, 11. iv. (15663, 15664, 15665). 
— Farcoxzni, Hook. fil. Chiabanjan, where it is very plentiful, с. 10,300', 5. v. 
(15562, 15581, 15582); in fruit, ibidem, coll. Ribu, October 1913 (18442, 
18443, 18444). 
This form, which seemed to me predominant on the Nepal frontier range 
from Sandakphu to Chiabanjan, has uniformly cream-coloured flowers, 
spotted in the throat, from 25 to 35 in the truss, about 4 cm., or less, across 
and the same in length. Ovary very woolly and filaments hairy. Capsules 
З to 4 см. long and 15 to 18 mm. in diameter. Leaves averaging 20 by 
11 em., but some 30 by 14 em. The upper surface copiously and deeply 
wrinkled ; the under surface buried in thick ferruginous tomentum. 16 
seems to prefer the slopes and hollows and to avoid the exposed ridge, 
where //odgsoni and Campbellie flourish. I did not notice any Falconer 
on the summit of Tonglo, where there is a fine group of Campbellic. 
—— — Hopeson1, Hook. fil. Between Chiabanjan and Singalela, c. 11,000', 5. v. 
(15579, 15580), the bluish pink form usual in cultivation; below the 
summit of Singalela, c. 11,500', 5. v. (15576, 15577), splendid imperial 
purple; much finer than the usual form. The leaves are longer in pro- 
portion than those of Falconeri, varying in my specimens from 18 by 7 cm. 
to 40 by 12 em. The surface smooth above and densely coated with а pale 
scaly indumentum ( as seen without use of the microscope) beneath. The 
ovary is densely tomentose (not “glandular scarcely pubescent ” as stated 
by Clarke in Fl. Brit. Ind.), but the filaments are glabrous or almost so. 
The fully developed trusses bear from 25 to 35 flowers. The capsules 
(judging from Clarke's Jongri specimen) are about 34 сш. long and only 
5 mm. in diameter—quite different in shape from those of Falconeri. 
DECIPIENS, mihi (sp. nov.) Arborescens; folia elliptica vel obovato-elliptica, 
basi aut angustata aut subcordata, circa 20-22 cm. longa, 9-11 cm. lata, 
supra propter venulas impressas erebre rugosa, sed forsan minus conspicue 
quam in А. Falconeri ; juniora subtus tomento ferrugineo detersili (ei R. Fal- 
coneri simili, sed minus denso) obsita, quo deterso persistit indumentum 
pallidum, quasi lepidotum, ei А. Hodgsoni (sine microscopii usu) non 
omnino absimile,  Petioli, ut in affinibus, circa 3-31 cm. longi, robusti. 
Corymbi terminales, 25-30-flori, pedicellis circa 2 cm. longis, fructiferis 
vero usque ad 5 em. productis. Calycis lobi, ut in affinibus, brevissimi. 
Corolla purpureo-rosea, ei А. Hodgsoni forma et colore similis. Ovarium 
tomentosum. Filamenta sparse pilosula. Capsule 4—5 cm. longs, 10— 
13 mm. late, ideoque inter eas А. Hodgsoni et №. Falconeri intermediz, sed 
hisce propiores. 
Foliis ad №. Fulconeri, florum colore ad R. Hodgsoni accedens, sed capsulis 
ambiguus, varietas hucusque indescripta Æ. Falconeri floribus purpureo- 
roseis (non carneis) videretur, nisi capsulis nonnihil discrepuisset. In loco 
natali nimis copiose provenit ut pro hybrido À. Falconeri et R. Hodgsoni 
habeatur.
