BETULACEAE. — CARPINUS 431 



tree 8 m. tall; young fruits); Fang Hsien, high mountains, rare, June 

 1901(Veitch Exped. No. 2102; tree 7 m. tall; young fruits). Eastern 

 Szech'uan: Wushan Hsien, A. Henry (No. 5520; ? also No. 5520^^ = 

 C. faginea Burkill); same locality, A. Henry (No. 7020'^; ripe fruits); 

 Tchen-keou-tin, P. Farges (type, ex Franchet). 



This is a very distinct species with almost simple setose serration of its small 

 long-pointed leaves. Wilson's No. 1809 with male flowers seems to belong here. 

 These flowers may be described as follows: Amenta mascula nondum satis evoluta 

 ad 2 cm. longa, sessilia, rhachi villosa; bracteae oblongae, subacutae, apice intense 

 brunneae, ceterum flavido-olivaceo-brunnescentes, utrinque glabrae, margine 

 apice excepta ciUatae, 5-6 mm. longae; stamina circiter 8, toro piloso; thecae sepa- 

 ratae eUipticae concolores apice ct etiam facie antica piUs longis sericeis instructae, 

 filamentis subaequilongis apice tantum partitis sufi"ultae. 



In shape the male bracts resemble those of C. cordata, var. chinensis more than 

 those of the other species of central China. The species was misunderstood by 

 Henry and Bean, who apparently referred to it plants belonging to C. Turczaninovii, 

 var. ovalifolia (see p. 427). I have not seen in cultivation a plant which 1 could 

 refer to C. polyneura.
