204 BALFOUR—NEW SPECIES OF RHODODENDRON. 
Eastern Siberia. Well ween the plant is, although as 
Maximowicz has pointed out the figure leaves something 
to be desired. In 1838* soa Candolle establishe d the genus 
its collector regarded as a distinct species. To ae as

evteneie the distribution of the species by including, in addition 
to plants from many stations in Eastern Siberia, a plant collected 
by T. Thomson at Kishtwar in the N.W. Himalayas. He. 
qualifies the identification, it is true, by the comment upon the 
dried specimen, “ spec. flor. fere destr.,’’ a remark no less applic- 
able to the specimen in the Edinburgh Herbarium. I suspect 
that Maximowicz may have been influenced in this determina- 
sheet Osmothamnus fragrans, DC. But Thomson’s Kishtwar 
plant is not Rh. fragrans, Maxim. It is yellow-flowered, not 
rose-flowered or white-flowered, and it has tet ao 
ud scales, which are absent from Rh. fragrans, Maxim., and 
shows many other points of difference.[ We must Teak upon
