Ad descriptionem addenda v. emendanda: Arbor ad 23 m. alta.; ramuli novelli 
(v. surculorum) hirtello-pubescentes v. glabri, hornotini annotinique fructiferi 
plerique glaberrimi, 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 em., 
minora angustiora 5-8 cm. longa, 2.5-4 em. lata, majora latiora ad 10 em. longa et 
5-5.5 em. 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. sureulorum utrinque 
plus minusve scabra, subtus vix discoloria, margine grossius crenato-serrata v. 
crenata, ad 11 em. 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 em.) longi. 
NORTHEASTERN ASIA. Korea: Quelpaert “in pago Kang-kyeng"?, 
July 1908, Taquet (No. 1376; “fruit gros”; fruit not yet ripe, pedicels rather 
short); same locality, “ 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). 4 
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 locality, Botanieal 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 distinctly 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
