BALFOUR—NEW SPECIES OF RHODODENDRON. 291 
plant. It is the plant to which gardening books so 
often refer as Rh. anthopogon, D. Don. Characters 
of it are :— 
1. Flowers yellow from the outset in large trusses ; 
2. Foliage-bud scale-leaves are persistent. 
More than this, the N.W. Himalayan plant is, as I shall 
explain presently, that which Maximowicz took to be his Rh. 
fragrans, Maxim. spread into the Himalaya, but it is not that 
species. It has to be named, and I call it Rh. hypenanthum,* 
Balf. f. Specimens of it in the. Edinburgh Herbarium are— 
Kishtwar (T. Thomson, sub nom. Osmothamnus fragrans) ; 
N.W. India (J. L. Stewart) ; Keylang, Lahaul (Watt, Nos. 2463, 
2504); Kiltu Kunda (Watt, No. 3337); Kukti Village (Watt, 
No. 2522) ; Murali (Watt, Nos. 8641, 13,576) ; Kulu (Watt, No. 
13,631) ; Garhwal (Duthie, No. 941); Kashmir (Duthie, No. 
11,021) ; Galja Byans (Reid) ; Dakwani (Reid) ; Bashahr (Lace, 
No. 231) ; Chamba (Lace, No. 1578); Kilas (Minniken). A 
full description of this species will appear shortly. 
There is yet to be noted a further confusion of species under 
the name Rh. anthopogon. 
The definition of Rh. anthopogon, D. Don given by Clarke 
in the Flora of British India ft was not fortunate in the 
interests of precise knowledge. Instead of sifting relation- 
ships of described forms, Clarke seems to have gone to Maxi- 
mowicz’s story of East Asiatic Rhododendrons, and to have 
transferred to Rh. anthopogon, Don the whole of the species 
therein described by Maximowicz. The outcome of Clarke’s 
combination of forms is that the Rh. anthopogon of the Flora 
of British India becomes a chimaera suggested by four already 
described species—Rh. anthopogon, D. Don, Rh. fragrans, Maxim., 
Rh. micranthum, Turcz., and Rh. parvifolium, Adams, along 
with one hitherto undifferentiated species—Rh. hypenanthum, 
Balf. f.—and also probably Rh. haemonium, Balf. f. et Cooper. 
Franchet ¢ has noticed the heterogeneity of the Rh. antho- 
pogon of the Flora of British India. When dealing with Rh. 
rufescens, Franch., a West Chinese species, he says :-— 
‘La délimitation spécifique est difficile & établir dans le 
petit groupe des Osmothamnus, dans lequel il n’est guére 
possible de ne voir qu’une seule espéce, comme l’ont pensé 
quelques auteurs. Il suffit, pour s’en convaincre, d’examiner 
* Rh. hypenanthum, Balf. £—Species Rh. anthopogoni, Don milis sed 
alabastri perulis per annos plurimos verticillatim persistentibus floribusque 
ab initio aureo-luteis facile distinguenda.
