74 BALFOUR—NEw SPECIES OF RHODODENDRON. 
Chinenses Forrestianae.* But it is not Franchet’s Rh. san- 
guineum as that appears in Soulié’s plant under No. 1015, of 
which we have specimens for which I am indebted to M. 
Lecomte of the Paris Herbarium, though it belongs to the 
same phylum. Its marks of recognition are: first of all the 
dark colour of the corolla and the larger typically oblanceolate 
leaves ; in addition, it has much smaller buds and scale-leaves 
covering them, leaves more rugulose above, fewer-flowered 
umbels, smaller bracts, stamens with white puberulous not 
glabrous filaments. 
Rh. sanguineum is only briefly diagnosed by Franchet. I 
translate here what he says :— 
Rhododendron sanguineum, Franch.,} in Journ. de Bot., xii 
(1898), 259. 
‘‘ Leaves most shortly petiolate obovate or oblong-obovate, 
4-6 cm. long 2-2.5 cm. broad rounded at the apex an 
mucronate opaque above glabrous clad beneath with a very 
thin white stratum. Flowers 6-10 loosely congested blood- 
corolla with glabrous filaments. Ovary rufously lanate ; style 
glabrous ; stigma capitate thick.

1015. — 1895. 
* r Rh. ‘haematodss, Franch., which it is very like in 
ainsi "Tr differs, however, in— 
“ The leaves without tomentum beneath even when young. 
“ The calyx, of which the lobes are not developed.

vata, apice rotundata cum mucronulo, supra opaca, glabra, subtus strato 
poriaan mo albo ves tita, 4-6 cen mt. longa, 20-25 mm. lata; flores 6—10, laxe

breviter et laxe lanuginosis ; calycis lobi vix evoluti; corolla 30-35 mm. longa, 
campanulata, 5-loba; stamina ro, corolla breviora, filamentis glabris ; ovariu 
rufo-lanatum, stylo glabro, stigmate capitato crasso.

15). 
Newnig 2 du am haemaiodes, dont il a tout A fait aspect, il en différe par son 
; par sa corolle a 5 lobes et ses étamines 
au nombre de 10; par ses deniiien dénriar-vuce de tomentum en dessous, méme 
e. 
La couche crustacée qu’on observe a la face inférieure des feuilles de quelques 
Rhododendron n’est souvent que le strate inférieur d’un véritable tomentum ; 
mais dans le Rh. Sanguineum, ainsi que dans le Rh. lacteum et quelques autres, 
Yindument laineux fait réellement défaut.
