BALFOUR—NEW SPECIES OF RHODODENDRON. 93 
hairs which in the type are so numerous and have such curled 
interlocking branches that the presence of glands is concealed 
and this probably accounts for the omission of reference to 
glands in the descriptions of Rh. Falconert. In some forms of 
what is called Rh. Falconeri these hairs are comparatively few 
but I have not seen a specimen from which the hairs were entirely 
absent nor have I seen one from which the glands were absent. 
There is, however, more than one plant included in the RA. 
Falconert of Herbaria and probably also of gardens and investi- 
gation of the species is much needed. There is no trace in Rh. 
artzelum of the bearding on the petiole which marks RA. eximium. 
The cup hairs of the indumentum are here much shorter 
than those of Rh. Falconeri and Rh. eximium, but have the stiff 
branched habit which is so conspicuous in these, and they can 
be separated from one another without difficulty. 
Rhododendron australe, Balf. f. et Forrest.* (Ovatum.) 
A slender-branched twiggy shrub as much as 2.5 m. high. 
Branches a year old about 1.5 mm. in diameter pale green 
densely pubescent with the curved simple (fish-hook) hairs of 
the Ovatum series also glandular with long stoutly stalked 
ovoid glands sprinkled amongst the hairs, the indumentum 
persisting more or less until decortication after three years or 
so. Annual growths usually about 5 cm. long with the foliage- 
leaves more or less clustered at the top and as they persist for 
about 3 years they form false whorls on the stems demarcating 
the successive annual growths. Mature foliage-buds unknown. 
Leaves petiolate as much as 9.5 cm. long sometimes the lower 
ones on the twig distant from the apical clustered ones ; 
lamina papery about 7.5 cm. long and 3 cm. broad oblong or 
oblong-lanceolate or oblong-oval, apex acuminate and tapered
