Ad descriptionem addenda v. emendanda: Arbor ad 23 m. alta.; ramuli novelli 

 (v. eurculorum) hirtello-pubescentes v. glabri, hornotini annotinique fructiferi 

 plerique glaberrirai, subangulati, intense brunnescentes v. subfusci, ut vetus- 

 tiores cinerascentes lenticellis numerosis discoloribus obtecti; gemmae oblongo- 

 ovatae, acutae, adpressae, perulis brunnescentes ad marginem intense coloratis et 

 tenuissime ciliatis in dorso subhirtellis cinctae. Folia ramulorum fructiferorum late 

 ovata V. ovato-oblonga, basi inaequali rotundata v. plus minusve acuta, nervis ba- 

 salibus paulo in petiolum productis, apice subsensim acuminata v. fere caudata, 

 margine ima basi excepta satis anguste arguteque serrata serraturis 4-6 pro 1 cm., 

 minora angustiora 5-8 cm. longa, 2.5-4 cm. lata, majora latiora ad 10 cm. longa et 

 5-5.5 cm. lata, supra satis viridia, in costa nervisque impressis sparse pilosa, ceterum 

 glabra, levia, subtus discoloria, albo-viridia v. cinerascentia, in facie sub microsco- 

 pio plus minusve reticulato-papillosa, in costa nervisque elevatis sparse pilosa, vix bar- 

 bata, rete nervorum paulo prominulo, nervis lateralibus a costa exeuntibus utrinsecus 

 basalibus 2 inclusis 3, rarius 4, plantarum juvenilium v. surculorum utrinque 

 plus minusve scabra, subtus vix discoloria, margine grossius crenato-serrata v. 

 crenata, ad 11 cm. longa et ad 6 cm. lata; petioli 6-11 mm. longi, glabri v. in sulco 

 superne pilosi v. in plantis juvenilibus surculisve hirtelli. Flores adhuc ignoti. 

 Fructus etiam juveniles glabri, maturi nigri, ut videtur subnitentes, globosi?, 

 circiter 8 mm. crassi; putamina brunnescentia, ovata, hilo lato obtusa v. plus 

 minusve tridentata et foveolata, ceterum in facie plus minusve irregulariter foveo- 

 lata et costata v. gibbosa, costa mediana distincte elevata, circiter 7 mm. longa et 

 5-6 mm. crassa; pedicelli glabri, 1.8-2.3 cm. (v. in Taquet's No. 1376 tantum 

 1.3-1.5 cm.) longi. 



NORTHEASTERN ASIA. Korea: Quelpaert "in pago Kang-kyeng "?, 

 July 1908, Taquet (No. 1376; "fruit gros"; fruit not yet ripe, pedicels rather 

 short); same locaUty, " in sylvis," alt. 1600 m., October 1, 1910, Taquet (No. 

 4418; with ripe fruits, stones very similar to those of Sargent's specimen from 

 Moiwa-yama). 



JAPAN. Hokkaido: prov. Ishikari, Moiwa-yama (sterile co-type, ex Koid- 

 zumi); same locality, July 30, 1914, E. H. Wilson (sterile); same locality, "hill 

 near Sapporo," deep moist soil, September 18, 1892, C. S. Sargent (tree 17-20 

 m. tall, girth 5.4 m., with almost ripe fruits) ; probably same locality, Sapporo, wild, 

 September 1885, K. Miyabe (sterile, named C. sinensis) ; Sapporo, Garden of the 

 Forest Department, September 23, 1892, C. S. Sargent (shoot from young plant); 

 same locaUty, Botanical Garden, May 1914, K. Miyabe (with young leaves and 

 very young fruits, named C. Bungeana); prov. Kitami, isl. Okujiri (sterile type; 

 ex Koidzumi). Hondo : prov. Shinano, bank of the Kiso-gawa near Fukushima, 

 October 27, 1892, C. S. Sargent (tree 20-23 m. tall; fruits apparently shining black) ; 

 prov. Mino, Nakatsugawa, September 6, 1905, J. G. Jack (with almost ripe fruits). 



According to Koidzumi this species has also been found in the province Uzen and 

 Iwashiro in Hondo and in Shikoku, prov. Awa, Tsurugi-san. I have not seen a type 

 specimen, but Wilson's sterile specimen from the Moiwa-yama agrees well with the 

 author's description. In Sargent's fruiting specimen from the same locality the 

 stones are distinctl}^ gibbous and ribbed on the surface and sharply dentate and 

 pitted at the narrow end, while the stones of the specimens from Kiso-gawa and 

 Nakatsu-gawa have a very obtuse apex and are more or less distinctly pitted and 

 gibbous. The specimens from Quelpaert certainly belong to this species. There
