filaments and oblong anthers, and a minute hirsute rudimentary ovary; the pistillate 

 on shorter simple or panicled aments or scattered at the base of the staminate 

 inflorescence, the cymes urrounded by an involucre of imbricated scales; calyx 

 urn-shaped, the short limb divided into 6 obtuse lobes; abortive stamens inserted 

 on the limb of the calyx and opposite its lobes; ovary sessile on the thin disk, 

 3-celled after fecundation, with 3 spreading styles terminating in minute stigmas, 

 and 2 ovules in each cell attached to its interior angle. Fruit maturing at the end 

 of the second season, its involucre inclosing 1-3 nuts, ovoid or globose, sometimes 

 more or less depressed, rarely obscurely angled, dehiscent or indehiscent, covered 

 by stout spines, tuberculate or marked by interrupted vertical ridges; nut more 

 or less angled by mutual pressure when more than 1, often pilose, crowned with 

 the remnants of the style, marked at the base by a large conspicuous circular 

 depressed scar, the thick shell tomentose on the inner surface. Seed usually solitary 

 by abortion, bearing at the apex the abortive ovules; cotyledons plano-convex, fleshy, 

 farinaceous. 



Castanopsis inhabits California with one species, and southeastern Asia where it is 

 distributed with about twenty-five species from southern China to the Malay Archi- 

 pelago and the eastern Himalayas. 



Castanopsis, from Kouyrava and fyis, in allusion to its resemblance to the Chestnut-
