the type of the species which is no longer in cultivation in 
that house. ’ 
It is a singular fact, that though the province of Sikkim 
has been thrown open to collectors and travellers for 
upwards of thirty years since the first Rhododendron seeds 
were sent home from its mountains, there has been no 
addition to the number of species found there in 1849. 
These amounted to thirty (or forty, including strongly 
marked varieties published as species), of which more than 
half were new to science, and only three were known in 
cultivation. On the other-hand, later collectors have added 
not a few varieties to the known kinds, some of which are 
exceedingly puzzling, notably the form of R. Falconeri and 
of R. cinnabarum.: The journeys of Mr. Booth, collecting 
for the late Mr. Nuttall in the neighbouring country of 
Bhotan, resulted in an addition of eight new kinds, and of 
a number of varieties or forms of the previously discovered 
Sikkim ones. Altogether twenty-seven species are known 
from Bhotan, of which eighteen are natives of Sikkim, and 
one of countries south of Bhotan. Putting these data 
along with the fact that the Bhotan Alps have never been 
explored to a height at which Rhododendrons are found in 
Sikkim, it follows that a rich harvest of the genus remains 
to be garnered in the former country. 
Further east in the Indian Alps the only country whence 
Rhododendrons have been collected is Munnepore, which 
has been visited botanically by Dr. Watt alone. That inde- 
fatigable collector found many species there, from seeds of 
which a number of young plants are being reared at Kew; 
but judging from the dried specimens that accompanied 
the seeds, these seem to be for the most part, if not wholly, 
either Bhotan species or forms of them.—J. D. H.
