Chaenomeles lagenaria Koidz. var. cathayensis n. var. with nar- 

 rower more closely and sharply serrulate leaves more or less 

 brownish pubescent on their underside, at least on the midrib. The 

 style seems to be always villous at the base. This is the common 

 wild form in central China and is probably the phylogenetic type 

 of this species. C. lagenaria var. Wilsonii n. var. [Cydonia Mallardü 

 Gard. Chron. non Carriere). 



Rosaceae subfam. Rosoideae by A. Rehder and E. H. Wilson. 



Rhodotvpus kerrioides S. etZ. and Kerriajaponica no new species. 



Potentilla fvuticosa var. albicans n. var., differs from var. vul- 

 garis Willd. chiefly in the white-tomentose under surface of the 

 leaflets. A number of well-known varieties of this species have been 

 found btit no other species. 



Rosa multiflora var. cathayensis n. var. with pink flowers R. 

 multißora var. carnea f. platyphylla n. comb.; R. glomerata n. sp. 

 distinguished by its large leaflets with strong reticulale venation 

 and villose pubescence on the underside, by its large membranous 

 stipules, by its short-peduncled dense corymbs, by the villose 

 tomentum on the pedicels and calyx and by its orange colored fruit. 

 It is related to R. longicuspis Bert., which is nearly glabrous every 

 where and has shining green leaves with much less prominent 

 venation, flowers on long^jedicels, and a very much larger red or 

 scarlet fruit. R. Helenae n. sp., distinguished by its large ovoid to 

 obovoid ellipsoid fruit. It is perhaps most closely allied to R. Brii- 

 nonii Lev., which has a paniculate corymb and smaller globose 

 fruits. R. filipes n. sp. well characterized by its glabrous shoots and 

 leaflets which are gland-dotted on the underside, by its very large 

 paniculate inflorescence of moderately large flowers on filiform 

 pedicels and by its small globose fruit covered with bloom. It may 

 be compared with R. Brunonii, which, however, is a pubescent 

 plant. R. Roxburghii f. normalis n. f. In the remarks to this species 

 one finds R. Roxburghii var. hirtula n. comb. R. chinensis f. spon- 

 tanea n. f., R. Davidii var. elongata n. var., distinguished by its 

 fewer flowers, its larger more elongated fruit and by its usually 

 larger leaflets. R. Movesii f. rosea n. f. with large pale pink flowers 

 and large leaves. R'. Murielae n. sp., perhaps most closely related 

 to R. persetosa Rolfe, which is a much more vigorous plant with 

 very densely setose stems, larger leaves of fewer differently shaped 

 leaflets. much branched, many-flowered corymbs of pink flowers 

 and globose fruits. It may also be compared with R. sertata Rolfe, 

 which has pink flowers on shorter pedicels, large bracts and bract- 

 lets, leaves composed of fewer. differently shaped leaflets, stems 

 slightlv and rarely setose, and globose fruits. R. Giraldiii. glabrius- 

 cula n. f., the leaflets are glabrous except for a few straight appres- 

 sed hairs on the lower surface of the midrib. R. Giraldii var. venu- 

 losa n. var. with leaflets, which are very markedlv reticulate on 

 the under side. R. graciliflora n. sp., has no close relationship with 

 any other Chinese Rose. It somewhat resembles R. Sioeginsowii 

 Koehne, but differs in the slenderer pedicels, in the entire sepals 

 and chiefly in the absence of the bracts at the base of the pedicel. 

 By the laUer character the species is removed from the group of 

 Cinnamomeae and must be referred to the Pimpinellifoliae. From 

 R. spinosissima L. it differs chiefly in the doubly serrate leaflets 

 aud in the elongated receptacle. It "has yellow flowers. R. omeieusis 

 f. pteracantha n. comb. [R. sericea f. pteracantha Franch.). After the 

 description of Wilson's specimens we find a conspectus of the
