BALFOUR—NEW SPECIES OF RHODODENDRON. 39 
honeycombed scintillating surface, and though bistrate has not 
got the very long branched hairs of the upper stratum which 
characterise Rh. citriniflorum and make its indumentum so much 
thicker and so much looser on the surface Then the indu- 
mentum of the ovary is eglandular—there are none of the glands 
that occur in Rh. citriniflorum. In the flower the calyx supplies 
a most distinctive mark, for here it is larger, with membranous 
lobes which spread out like a collar around the base of the 
corolla, becoming reflexed, and as they wither often falling off. 
The lobes are, moreover, glabrous and have only a few short 
and its allies. 
Rhododendron colletum,* Balf. f. et Forrest.7 
Shrub as much as 4 m. high with thick branches. | Branchlets 
a year old pale green often enclosed at base by persistent sticky 
scale-leaves of foliage-bud, apparently coated with floccose red 
and brown hairs which soon fall off. Scale-leaves of the pyra- 
midal foliage-bud crustaceous semi-lunate to ovate and obovate 
with a thinner fringed margin, dark-brown, viscid with external 
sessile glands and short hair-glands, inside the scale-leaves 
* xolintéc, glued together—in allusion to the sticky bracts.
