BETULACEAE. — CARPINUS 427 



Franchet's plate, but agrees with Winkler's statements. The outer (dentate) mar- 

 gin of the bracts is notlobed at the base, but there is a basal lobe at the inner (entire) 

 margin. The dilTerences between the Kiangsi plants and the Ilupeh varictj'^ are 

 apparently very shght, and more copious material probably will show that both 

 are the same and may represent a good species confined to central Cliina. Then 

 the oldest name would be C. Fargesii Franchet.

Western Szech'iian: Mao-chou, valle^^ of Min River, alt. 2300 

 m., September and October 1910 (No. 4105; tree 7-17 m. tall, girth 

 1.2-2.4 m.; fruiting branchlets); between Lungan Fu and Sungpan 

 Ting, mountains, alt. 2300 m., August 1903 (Veitch Exped. No. 4489; 

 tree 8 m. tall; almost ripe fruits). Eastern Szech'uan: Wushan 

 Hsien, A. Henry (No. 7020; type of var. ovalifolia; fruiting branches); 

 same locality, A. Henry (No. 7219; co-tj^pe, ex Winkler); district of 

 Tchen-keou-tin, Farges (without number, fruiting branchlets; and 

 No. 1273; ex Winkler). Kansu: Lotani road from Min-chou, alt. 

 2600 m., W. Purdom (No. 787; tree 7 m. tall; fruits). 



The specimens which I doubtfully unite under this variety ngree with each 

 other in their fruiting bracts of similar shape which differ from those of the typical 

 form in being only toothed and not lobulate on the outer margin. The leaves, too, 

 are somewhat more ovate-oblong and sliglitly more elongated at the apex than those 

 of the typical C. Turczaninovii Hance. There is no real difference in the pubescence 

 of the upper or lower surfaces of the leaves; this is variable in both the varieties. 

 Certainly var. ovalifolia needs further investigations. From C. polyncvra Franchet 

 it differs clearly in the glabrous nutlets, and in the serration of its leaves which is dis- 

 tinctly compound with short teeth. Judging by a s]iecimen cultivated at Kew which 

 is referred by Henry and by Bean to C. pohjneura Franchet, the male flowers are 

 different from those of this species. I describe them as follows: Amenta mascula 

 sessilia, usque 3 cm. longa et circiter 0.7 cm. crassa, densa, rhachi dense sericeo- 

 villosa; bracteae late ovatae, acutae, ima apice fere nigrae, cetcrum parte sui)eri- 

 ore rubro-brunneae, parte inferiore olivaceae, intv.s glaljrae, margine satis ci'iatae, 

 extus plus minusve adpresse sericeae; stamina circiter 10, toro piloso; thecae 

 separatae, ellipticae, concolores, apice et etiam antica parte superiore pilis longis 

 sericeis instructae. filamentis subbrevioribus tantum apice partitis suffultae. 



There is a sjiecimen collected by Wilson, Wushan Hsien, ravine, May 1900 

 (Veitch Exped. No. G18; tree 3 m. tall), the male flowers of which are similar, but 

 the bracts are nearly round, more obtuse, and even more ciliate. I am not quite 

 sure whether this specimen belongs to our variety or to another species.
