292 BALFOUR—NEW SPECIES OF RHODODENDRON. 
la synonymie du Rh. anthopogon, Don, telle qu’elle a été établie 
dans le ‘ Flora of British India.’ ”’ 
I need say no more here about the parts of Clarke’s com- 
‘bination that are to be segregated as the true Rh. anthopogon, 
Don, and Rh. hypenanthum. Of the others :-— 
Rh. fragrans, Maxim. finds its nearest alliance with Rh. antho- 
pogonotdes, Maxim. and other Chinese species. See on p. 293. 
Rh. parvifolium, Adams is not a near ally of Rh. anthopogon, 
Don. It belongs to the Lapponicum series, represented out- 
side Asia as well as in W. Asia by Rh. lapponicum, in the 
Himalayas by Rh. nivale, Hook. f. and in West China, where 
it seems to attain its maximum of over a score of species. 
See p. 299. » 
Rh. micranthum, Turcz. is a species which has been much 
misunderstood—it is neither in the Anthopogon nor the 
Lapponicum series. 
Rh. haemonium, Balf. {. et Cooper may be best described as 
an Eastern form of Rh. hypenanthum of the Western Himalaya. 
The plants in dried specimens are not unlike, but the Bhutan plant 
never has the persistent foliage-bud scale-leaves of Rh. hypen- 
anthum, and is recognisable at sight. They both have the same 
intensely yellow corolla. From Northern and Eastern Sikkim 
there are specimens in the Edinburgh Herbarium which are 
probably this species Rh. haemonium, and possibly some of 
such Sikkim plants may have been included in the aggregate 
that appears as Rh. anthopogon, D. Don in the Flora of British 
India. Rh. haemonium is certainly not the true Rh. antho- 
pogon, Don, and is very different from the S.W. Sikkim plants 
of the group. 
FRAGRANS SERIES, 
I give the name Fragrans to a series of species distinguished 
from those of Anthopogon by never having agglutinate 
rufescent under-leaf indumentum, and from those of Cepha- 
lanthum by never having a lax open fawn-coloured under-leaf 
indumentum. The general characters of the series are :— 
Aromatic shrubs with short-stalked small leathery leaves 
ultimately dark green above and pale fulvous beneath, with 
peltate shortly stalked uniform scales producing a compact 
not loose or agglutinated surface of scales; the umbo of the 
scales usually with a bright yellow ring of secretion and ‘girt 
by a narrow few-armed fringe. Many scales of the twigs and 
petioles lose their disks, becoming setae. Bracts of the capi- 
tate umbel lepidote and fringed falling after flower-opening. 
_ Calyx unequally lobed. Corolla fleshy, villous at throat, glabrous 
outside, rose, white, or yellow. Stamens puberulous. Ovary
