A species which recalls Rh. phaeochrysum, Balf. f. et W. W. 
Sm., but is smaller in all its parts and is at once recognised by 
the bright yellow petioles and midribs of the same colour where 
the indumentum is remove 
Rhododendron arizelum,* Balf. f. et Forrest.t (Falconeri.)

I cm. in diameter glabrescent blackening, traces of the tomentum 
remaining until decortication, bark flaking off leaving a pale 
reddish smooth surface. Foliage-buds conical large; 5 or 6 
outermost scale-leaves imbricate elongated triangular tapering 
rom a broad base to an acuminate tip, or with a wide basal 
portion and a long tail, insertion broad half-moon shaped, hard 
woody keeled, cobwebbed outside, glabrous somewhat glossy 
inside, margin ciliate with cobwebbed hairs which form a tuft 
at the tip ; inner bracts convolute ovate and mucronate slightly
