10. Castanopsis castanicarpa, Spack, Hut I /. Pkm. xi. 185. 



Young branches, petioles, and inflorescence softly pubescent; all other pints glabrou 

 Leaves sub-coriaceous, large, ovate-oblong or obovate-oblong, shortly acuminate, entire; th< 

 base acute; both surfaces, when adult, shining and glabrous; the reticulations minute, 

 distinct; nerves about 10 pairs, thin, but prominent beneath; length of blade 1<> to 1

 shorter than the leaves; the flowers solitary or in threes. Ripe inrolu <-e ovoid, about 

 1*25 in. long, pubescent, densely covered with straight, striate, flat, sub pubescent, sharp,

Chittagong : on low dry hills, — Roxburgh, Hooker. 



In Roxburgh's time this appears to have been rather a common speei s n ir 

 Chittagong, and Sir Joseph Hooker found it there in 1849-50. A collector, sent to th< 

 Chittagong Hills from the Botanic Garden, C leutta, in 1880 foi the purpose oi 

 collecting this failed, however, to find a single tree; it must therefore now be exterminated, 

 or nearly so, in the Chittagong district— a fate, alas! not peculiar to this species. M 

 flowers of this are unknown.* 



* Note -Since the above was written, a ripe f railing-specimen (of which I give a figure has been sent to ■ 

 from a remote part of the Chittagong Hill Tracts by Mr. Dowling, a gentleman residing there, to whom I am 

 indebted for much assistance in the botanical exploration of that difficult country.
