ULMACEAE. — CELTIS 273 



or less impressed and not prominent. The pubescence and other characters are the 

 same as described in var. hetcrophylla Schneider on p. 282. C. Biondii seems to be a 

 widely distributed and variable species. The two varieties look rather distinct in 

 their typical forms and have also a different geographical distribution, but the 

 type seems to be connected with var. hetcrophylla by the specimens from Kiangsi, 

 the stones of which are globose and more distinctly pitted and gibbous; on the 

 other hand var. Cavaleriei cannot be separated as a species. 



The type may be briefly characterized as follows : Folia pleraque ovato-oblonga, 

 2-23^-plo longiora quam lata, margine plus minusve Integra v. ultra medium satis 

 breviter et acute dentata, adulta utrinque pilis sparsis adpressis instructa v. in facie 

 fere glabra. Putamina (an semper?) ovato-elliptica v. ovato-oblonga. Cetera ut 

 in var. heterophylla descripta. 



Celtis Biondii is a common tree at low altitudes in Hupeh and in Szech'uan and 

 is known in the vernacular as the P'o shu. In Chinese Herbals and other books 

 it is referred to as the Ch'ing-t'an shu. E. H. W.

A typo praecipue differt foliis adultis plerisque late ovatis v. ovato-

Western Szech'uan: west and near Wen-ch'uan Hsien, val- 

 leys, alt. 900-1600 m., September 1908 (No. 972; tree 10-17 m. 

 tall, girth 1.2-2.4 m., fruits orange; with ripe fruits); near Wa-shan, 

 Tung River valley, rare, alt. 550-650 m., September 21, 1908 (No. 

 933; small tree 7 m. tall, girth 0.6 m., fruits orange; with ripe fruits). 

 Kweichou: Pin-fa, September 4, 1902, J. Cavalerie (No. 394, type 

 of C. CawaZena; with ripe fruits). Yunnan: Mile district, Teng- 

 tien, old woods, November 1, A. Henry (No. 9938; tree 7 m. tall, fruit 

 red; with ripe fruits) ; Puerh Fu, alt. 1300 m., A. Henry (No. 13509; 

 tree 7 m. tall; sterile). 



Through the kindness of Mgr. Leveille I have received some leaves and fruits of 

 his type. It agrees well with Wilson's specimens. According to Henry the fruit 

 is "red," but it seems to have the same yellowish or brownish red color as in the 

 type the fruits of which are said by Wilson to be " orange." Otherwise there is 

 hardly any difference between the specimens from Yunnan and these collected by 

 Wilson. In No. 9938 the old leaves are distinctly reticulate beneath, although the 

 finest veinlets are not prominent but almost impressed. The fruits are mostly 

 2 (-3) on the same pedicel, but I have seen neither flowers, young leaves or branch- 

 lets. The stones are hardly distinguishable from those of var. heterophylla Schnei- 

 der or from those of Wilson's specimen from Kiangsi.
