FAGACEAE (Beech Family) 



Shrubs or trees. Leaves alternate, petioled, simple, pinnately 

 veined; stipules deciduous or none. Flowers- monoecious, small. 

 Staminate flowers in aments or heads; perianth 4-7-lobed; stamens 

 4-20. Pistillate flowers solitary or in clusters, each cluster of i or 

 more subtended by an involucre of bracts which become a cup or bur; 

 perianth 4-8-lobed, adnate to the ovary; ovary 3-7-celled; styles 

 as many as the ovary cells. Fruit 1-3 nuts. Seed i. 



A. Leaves serrate or dentate or entire, not lobed; filaments many times as long 

 as the anthers; pistillate flowers on the bases of the staminate aments. 

 B. Leaves entire, coated beneath with yellow persistent scales; involucre inclosing 

 1-3 nuts, very prickly with branched prickles. C. E. — {Castania is the genus 

 of the chestnut; Gk. opsis = like; hence chestnut-Uke.) 



Castanopsis chrysophylla (chinquapin) 



BB. Leaves enture or serrate or dentate, without scales beneath; nuts solitary; 



involucre covering only the base of the nut, not prickly or at least the prickles not 



branched. W. — (Perhaps from L. pascere = to feed; on account of the food 



in the acorns.) Pasania densiflora (chestnut oak) 



AA. Leaves often deeply lobed but in some serrate or entire; filaments not longer 



than the anthers; pistillate flowers not on the staminate aments; fruit a single nut 



(acorn), partly inclosed in a scaly cup which is not prickly. QUERCTJS (p. 75)
