198 S. Kurz — Description of a new Species of Tupistra. [No. 3, 



reticulatione satis obsoleta ; spicse fruetigerse \\ ped. eirciter longse, tomen- 

 tellae, glandes obovoideo-globosas, pollicem fere latse, lseves, styloso-apicula- 

 tse, pallide brunnese et nitidse, exsertse ; cupulse concavo-explanatse, margini- 

 bus plus minusve revolutis, crasse coriacese, extus ferrugineo-velutinse, intus 

 canescenti-sericese, liberge v. rarius basi tan turn connate, squamis nurnerosis 

 triangularibus parvis appressis obducta3. 



Hab. — Upper Assam (Falconer). Very nearly allied to Q. AmJterstiana, 

 Wall. 



5. Castanea divebsitolia, nov. sp. 



Arbor 40 — 60-pedalis, novellis fulvo-pubescentibus ; folia valde variabi- 

 lia, novella cbartacea, ovato-oblonga ad ovata, 7 — 9 poll, longa et 4 — 4J poll, 

 lata, petiolo semipollicari pubescenti suffulta, in nervis utrinque parum 

 pubeseentia, nervis reticulatione laxa crassa et conspicua ; adulta multo 

 minora, coriacea, elliptico-oblonga, breviter et obtuse acuminata, 4 J — 6 poll, 

 longa, utrinque pagina v. petiolo et in nervis utrinque puberula et glabres- 

 centia, squamis minutis argenteis destituta ; panicule magnse et robustse, 

 apicibus ramulorum congregate dense fulvo v. cinereo-tomentose ; fructus 

 involucrum 1^ poll, fere in diametro, spinis obtectum ; spinae simplices, 

 stricte, pubescentes, circa 4 lin. longe. 



Hab. — Common in tbe drier hill forests of Martaban, at 3,500 — 5000 ft. 

 elevation. 



I describe this species as a Oastanea connecting Castanopsis (including 

 Lithocarpus) with Oastanea. This, of course, is quite a practical division 

 for the differences between all these genera are simply artificial ones.

(Received Sept. 30th ;— Eead Nov. 4th, 1875.) 



From amongst the many fine plants which I owe to the late Dr. F. 

 Stoliczka I have selected for description this new species of Tupistra, a o-enus 

 that has hitherto been supposed to be monotypic. The present species is 

 remarkable for its stiff robust erect spikes, those of T. nutans being short,
