BaLFour—NEw SPECIES OF RHODODENDRON. 07 
know in the series. I do not however know at what value to 
appraise fruit and seed character in rhododendron, for I have 
seen too few of them in fruit. 
I may note here that there is another series of rhododendrons 
with somewhat similar distribution to which may be given the 
name of Selense, presenting general features very like those of 
the Campylocarpum series but distinguished at once by a 
glabrous style on top of the glandular ovary. The species 
belonging to it are :— 
Rh. blandulum, Balf. f. et Mid. W. Yunnan : Tali Range, 
W. W. Sm. (1917). Western flank, 11,000- 
12,000 ft. (Forrest.) 
Rh. Fargesii, Franch. (1895). E. Szechwan: . Chenkow 
(Farges.) W. Hupeh, 6500~ 
9500 ft. (Wilson.) 
Rh. jucundum, Balf. f. et Mid. W. Yunnan: Tali Range, 
W. W. Sm. (1916). Western and Eastern 
flank, 10,000~-12,000 ft. 
(Forrest.) 
Rh. pagophilum, Balf. f. et S.E. Tibet: Doker La and 
Ward (1916). Ka-gwr-pw Glacier Valley, 
14,000-16,000 ft. (Ward.) 
Rh. panteumorphum, Ball. f. et W.N.W. Yunnan: Mekong- 
W. W. Sm. (rgx6). Salween divide, 11,000- 
7 12,000 ft. (Forrest.) 
Rh. rhaibocarpum, Balf. f. et E.N.W. Yunnan: Mekong- 
W. W. Sm. (1917). Yangtze divide and Chung- 
tien plateau, II,000-12,000 
ft. (Forrest.) 
Rh. selense, Franch. (1898). W.N.W. Yunnan : Mekong- 
Salween divide, Mt. Sela. 
(Soulié.) 
Rh. Stewartianum, Diels (1912). | W.N.W. Yunnan : Mekong- 
Salween divide, 10,000— 
11,000 ft. (Forrest.) 
In the Selense series there appears the same contrast in 
fruits as in the Souliei series. Rh. rhaibocarpum has a capsule 
in all characters like that of Rh. campylocarpum and it con- 
trasts with the short, nearly straight capsule of Rh. Souliet. — 
It is convenient for the time to segregate these species in 
the series I have named and thus to link together some of the 
now numerous species of rhododendron. But I think that 
hereafter it may be found that natural relationships call for a 
Tegrouping of the species, and that they all belong to and may 
be arranged by their affinities within a series for which we may
