ASSAM AND BOOTAN. 359 
described Oaks. Fresh flowers have not yet been seen, but from the 
appearance of the dried fragments they seem to be of a deep red. Since 
the above remarks were made, a plant in cultivation has made an 
abortive attempt at flowering, producing two stamens and a cluster of 
scarlet leaves. 
There are apparently two varieties: one with a glutinous pubes- 
cence; the other with appressed short strigose hairs. 
According to the herbarium of my friend Sir William Hooker, it 
appears that this species was observed in Bootan by the late Mr. 
Griffiths. The specimens are branches without flowers or fruit. 
Dedicated to the memory of my much-revered friend and botanist 
the late Dr. James Kendrick, of Warrington.

the Oola mountain, on the northern slopes of the Lablung Pass; ac-

the 20th of December, being very severe and continuous. Elevation

A tall erect shrub, 12-14 feet high, with a stem 3-4 inches in dia- 
meter. Branches covered with a whitish-yellow polished bark. Flower- 
buds large, the scales dilated and retuse, externally appearing as if 
varnished, internally silky. Leaves smooth, very thick and coriaceous,
