Primus japonica var. fukienensis, var. nov. 



A typo recedit ramulis junioribus dense minute pilosulis, foliis subtus 

 ad costa venasque sat dense interdum ad venulas sparsius hirto-pilosis, 

 pedicellis et calycis tubo breviter pilosis, sepalis latioribus extus pubes- 

 centibus intus puberulis, stylo basi piloso. — Hamuli graciles, tenues; 

 folia elliptico-ovata, 2.5-4 cm. longa, subito caudato-acuminata, basi 

 rotundata, breviter duplicato-serrata, supra breviter scabro-pilosula; 

 petioli pilosuli, 1-3 mm. longi; stipulae lineares, ad 6 mm. longi, interdum 

 extus pinnatifidae, longe glanduloso-ciliatae; pedicelli circiter 1 cm. 

 longi; sepala ovalia, glanduloso-serrulata, circiter 4 mm. longa; flores 

 deflorati tantum visi. 



Fokien: Without precise locality, April to June, 1905, P. T. Dunn 

 (Hongkong Herb. No. 2654, type, 2662). 



This new variety is nearest to P.^ japonica var. Nakaii, but differs in 

 its pubescent branchlets, the smaller less deeply and less doubly serrate 

 leaves, their shorter and broader acumen and the rounded base of the 

 leaf. It also shows some relation to P. japonica Oldhamii Koehne, with 

 which it agrees in the serration and shape of the leaves though they are 

 smaller and comparatively broader in var. fukienensis, but differs in its 

 pubescence which in P. japonica Oldhamii is present only on the midrib 

 and usually also on the veins beneath, though occasionally the very young 

 branchlets may be minutely puberulous and the sepals puberulous on the 

 inner surface. This variety seems also to be related to P. carcharias 

 Koehne of which I have seen no specimens, but the branchlets of that 

 species are described as densely hirsute with yellowish hairs, the stipules 

 are trifid and up to 12 mm. long and the leaves are much larger, densely 

 accumbent-pilose beneath and more loosely so above. 



Prunus japonica var. Nakaii, comb. nov. — P. Nakaii L6veill6 in 

 Fedde, Rep. Nov. Sp. vn. 198 (1909). — Koehne in Sargent, PI. Wilson, 

 i. 267 (1912). — Nakai, Fl. Sylv. Kor. v. 36, t. 22 (1916). 



Korea: Ouen-san, in lacunis montium, July, 1906, U. Faurie (No. 

 334, type). Pro v. Heian: in collibus Chinnampo, June, 1901, U. 

 Faurie (No. 77); Taijudo, French Mine, road-sides, common, alt. 400 m., 

 June 18, 1917, E. H. Wilson (no. 8636). Prov. Keiki: Koryo, 30 

 miles northeast of Kaijyo, road-sides, common, July 8, 1917, E. H. Wil- 

 son (No. 8748); Mountains behind Kaijyo, road-sides, August 20, 1918, 

 E. H. Wilson (No. 10596). Prov. N. Kaisho: Hoko, May 29, 1917, 



E. H. Wilson (No. 8493). 



I am unable to separate P. Nakaii L6v. from P. japonica Thunb. as a 

 species; in habit, general appearance, flower, fruit and leaf it differs 

 little from typical P. japonica except in the pubescence of the different 

 parts. The leaves of P. Nakaii are usually rather densely pubescent 

 beneath and less densely so or nearly glabrous above, the pedicels and 

 calyx-lobes vary from short-pilose to glabrous and the sepals are puberu- 

 lous on the inner surface, but in Wilson's No. 10596 the leaves are much
