SOME ADDITIONS TO THE FLORA OF THE EASTERN 
HIMALAYA. 
By W. W, Smith. 
Most of the plants referred to in the following pages formed part 
of a collection made in May- June 1905 by J. C, White, Esq., C.I.E., 
at that time Political Officer in Sikkim, during a tour along the borders 
of Tibet and Bhutan wherein was included a visit to Pari and Punakha. 
This collection he generously handed over to the Herbarium of the Royal 
Botanic Garden, Sibpur ; and he supplemented it by a further collection 
made in 1906-07 in Eastern Bhutan. 
Of the flora of Bhutan very little is known, and these collections 
are consequently of considerable interest. The flora of the western side 
of Bhutan probably bears a close resemblance to the adjoining parts 
of Sikkim and Chumbi ; and these collections support the view. At the 
same time many new species are to be got in this western portion and 
further east, Bhutan will no doubt eventually give a rich yield especially 
of alpine forms. 
The present collections contain several new species and also plants 
which have not come to light for over 50 years — plants collected by 
Griffith and by Booth, who are the chief and almost the only botanists 
who have ever been in the Bhutan Highlands. In the genus Primula 
besides the resurrection of Primula mollis Booth, two new species have 
come to light, a description of which is given below. 
I have included some new species from Sikkim.
