98 BALFOUR—NEW SPECIES OF RHODODENDRON. 
uQoX Rhododendron chloranthum,* Balf. f. et Forrest.+ (Tricho- 
cladum.) 
Deciduous-leaved shrub about 1 m. high with slender some- 
what twiggy branches and leaves deciduous after one season, 
the flowers appearing annually slightly before the leaves. 
Branches of the year green barely I mm. in diameter densely 
clad with long undulate setae covering a few distant whitish or 
yellowish peltate scales, the one-year-old whitish-grey branches 
more sparingly setose and often glabrescent, older branches dark 
grey and with vestiges of the setae and scales. Foliage-buds 
fusiform scale-leaves all deciduous as bud opens; outermost 
scale-leaves crustaceous bright brown rounded glabrous outside 
and finely and shortly ciliate above, followed by oblong-oval 
ones of like character, innermost scale-leaves somewhat mem- 
branous paler or somewhat greenish-yellow narrowly oblong- 
oval about 1.2 cm. long 3 mm. broad densely lepidote along the 
middle outside sparingly ciliate on margin below densely so over 
the rounded tip and around the red mucro ; young leaves con- 
duplicate-convolute glabrous above, lepidote and setulose below, 
setulose-ciliate ; foliage-buds in axil of one or two last leaves 
of flower-shoot, which are set close below the flower-bud, not 
developing and thus is left a short gap between the inflorescence 
and elongating lateral foliage-shoots below it. Leaves (not quite 
mature) petiolate as much as 4.3 cm. long; lamina thin papery 
oval or oboval as much as 3.8 cm. long 2 cm. broad, apex rounded 
often somewhat retuse at point of origin of short mucro, margin 
plane red setulose-ciliate, base broadly obtuse or rounded ; upper 
* ‘yhooss, green-yellow—in allusion to the flower-colour.
