PASAXIA. 



cupule: in a few the upper third, and in an extremely small number the upper half, of 

 the glans is naked. The latter somewhat resemble the fruit of Q. spicata, Sm. There 

 is also some variability in the breadth of the leaves. The typical form of leaf is 

 narrowly lanceolate, not more than 1*5 in. broad, but at the upper limits of the species 

 in Sikkim the leaves are elliptic-lanceolate and 3 inches or more broad. These broad- 

 leaved individuals have sometimes been supposed to belong to the species found by 

 Roxburgh in Chittagong, and named by him Q. acuminata (Fl. Ind. iii. 636). Specimens 

 of the true Roxburghian acuminata exist in no European collection which I have 

 consulted, and, until lately, there were none in the Calcutta Herbarium. I was there- 

 fore at one time inclined to believe that Roxburgh must have described two plants 

 under different names, calling his Sylhet specimens Q. fenestrate, and those from 

 Chittagong Q. acuminata; and his descriptions in the Flora Indica and his drawings in 

 the Calcutta Herbarium rather support this view. In order to settle this and some other 

 matters connected with the botany of Chittagong— a region which, except by Sir J. D. 

 Hooker, Dr. Thomson, and Mr. C. B. Clarke, has not been investigated since Roxburgh's 

 ti me — I sent a native collector there two years ago. And, amongst the specimens 

 collected by this man, there are excellent examples of Q. acuminata, Roxb., which having 

 once been seen, the suggestion of the identity of acuminata and fenestrata disappears 

 entirely from one's mind. Some of the specimens distributed by Wallich under his 

 No. 2784 as Q. fenestrata are undoubtedly Q. lancemfolia, Roxb.

Young shoots softly pubescent, sometimes furfuraceous. Leaves coriaceous, lance- 

 olate, acute or acuminate, entire, the base acute; upper surface scurfy, puberulous

9 to 10 pairs, rather prominent below, as is the midrib ; length of blade 3 to 5 in., 

 breadth 1*15 in. to 225 in.; petiole *3 in. to -4 in. Inflorescence terminal, the spikes (of 

 which one or two, and often more, bear female flowers) in panicles longer than the 

 leaves, Male flowers sessile, in fascicles of 3, with three unequal bracteoles; perianth 6- 

 partite ; stamens about 10. Female flowers in fascicles of 3, connate by their bases ; 

 styles 3, linear. Acorns on a stout rachis, much crowded, solitary (by abortion), or two 

 three together. Cupule sessile, woody, enveloping the sub-globular or turbinate-pyri- 



form glans except at its apex; -5 to -65 in. in diameter; its bracts pubescent outsid 

 connate except the apices which are free and form short striate tubercles.— Miq. in Ann

A form which has been collected by Messrs. Mann and Clarke differs sufficiently 



trom the type to be characterised as a variety.
