ROSACEAE. — SORBUS 275

Sorbus alnifolia, var. lobulata Rehder, n. comb. 

 Micromeles alnifolia, /3 lobulata Koidzumi in Jour. Coll. Sci. Tokyo, XXXIV. 

 art. 2, 69 (Consp. Rosac. Jap.) (1913). 

 Korea: Chinnampo, September 17, 1905, J. G. Jack; same locality, June 1901 

 and August 1906, U. Faurie (Nos. 82 and 305); Seoul, September 1906, U. Faurie 

 (No. 306). Korean Archipelago: Quelpaert, U. Faurie (Nos. 1552, 1554) 

 Taquet (Nos. 748, 758, 2824, 2825). 



Though the most extreme form of this variety as represented by Jack's speci- 

 mens which have orbicular-ovate leaves up to 9.5 cm. long and to 9 cm. broad 

 looks very distinct, the specimens from Quelpaert and from Seoul are intermediate 

 between the variety and the typical form. 1 suspect that these intermediate forms 

 represent, at least partly, Koidzumi's var. tiliaefolia. 



Sorbus alnifolia, var. submoUis Rehder, n. var. 

 A typo recedit foliis subtus tota facie villosa indumento plus minusve persistente 

 et corymbis receptaculis sepalis extus laxe lanuginosis. Folia ovata, basi plerum- 

 que rotundata, 4-5 cm. longa et 2.5-3.5 cm. lata. 



Hondo: north of Yum.oto, oak woods, alt. 1500 m., June 22-24, 1914, E. H. 

 Wilson (No. 6874, type; tree 10-14 m. tall, 0.60-1.25 m. girth, flowers white); 

 Mt. Mitsumine, October 1898, H. Shirasawa. Hokkaido: prov. Tokachi, 

 August 17, 1907, without indication of collector. 



This variety, which has comparatively small leaves and differs from the type 

 chiefly in the rather dense villose pubescence of their underside, seems to have been 

 sometimes confused with S.japonica Hedlund, which is easily distinguished by the 

 floccose white or whitish tomentum, the lobed, usually more or less rhombic leaves 

 and by the larger fruit.

* In the same year the combination Sorbus japonica based on »S. Aucuparia, 

 var. japonica Maximowicz was published by Koehne, but S. japonica Hedlund has 

 the priority by nearly one month, since his publication left the printing press on 

 July 6, 1901, as I was kindly informed by Dr. J. A. Bergstedt, librarian of the 

 Swedish Academy, while the number of Gartenflora in which Kochne's S. japonica 

 was published did not appear until August 1, 1901. This also gives priority to 

 Hedlund's S. commixta over S. japonica Koehne, which both refer to the same 

 species.
