50 JOUUNAL OF THE ARNOLD ARBORETUM [vol ii 



The exact native habitat of this form Is not known with ccrhiinty. Pur- 

 dom sent under No. 329 flowering specimens of M, baccata collected at 

 Ycnan Fu, Shensi, and it is probable that No. 327 under wliich ihe plants 

 were received from Veitch is a mistake for 329, as the number 327 is 

 represented by a Caragana in his collection. None of his flowering speci- 

 mens, however, agrees with our plant and no fruiting herbarium specimens 

 of 3/. baccata have been collected by Purdom. 



Malus floribunda Siebold var. brevipes, var. nov. 



A tyi)0 praeclpue recedit foliis minorlbus, floribus niinoribus, albidis, 

 circiter 2.5 cm. diam., pedicellis brevibus 0.8-1.5 cm. longis ut caiyx glabris, 

 I)etalis late ovahbus 1-1.2 cm. longis; stylis 3-4 quarta p:irte tantum con- 

 natis ima basi glabris et tantum versus apicem partis connatae si)arse vel 

 densius pilosis, fructibus subglobosis circiter 1 cm. diam. pedicello erccto 

 vel subcrecto 0.6-1.5 cm. longo suffultis. 



Cultivated at the Arnold Arboretum under No. 1R.*0 for many years, ori<,nna]ly 

 received as Pyrus SieboUlii probably from St. Petersbiirg; type sjiecirnens collected 

 May 19 and Octol)er, 1898, preserved in the herbarium of the Arboretum. 



This is a very peculiar form which in its leaf-characters agjecs with AL 

 floribunda, but the flowers are much smaller, only slightly pink, rather short- 

 stalked and the style Is more deeply divided and less densely ])ubescent. 

 The shrub looks particularly distinct in autumn with its more or less up- 

 riglit fruit on rather stout pedicels rarely more than 1 cm. in length. It is 

 not without hesitation that I refer this plant as a variety to M, floribunda, 

 but it shows no characters which point to hy])rid influence of any other 

 species, and from M, Sicholdii it difl'ers in the leaves wliich never show the 

 slightest tendency toward lobing. It may be nearer to the wild form, J/. 

 floribunda var. spontanea Koidzumi which according to a si)ecimen before 

 nic has smaller lighter colored flowers and smaller leaves than the culti- 

 vated typical form. 



Malus kansuensis Schneider f. calva, forma nov. 



A typo recedit pedicellis calycibusque extus et foliis subtus ab initio 



glabris, ranndis et petioHs basin versus sparse pilosis mox glabris.

This new form Is easily distinguished from the type by the absence of 

 pubescence from the inflorescence and the leaves. The original description 

 of Batalin Is chiefly based on Potanin's specimens of which he describes 

 the flowers with pubescent pedicels and calyx; in the description of the 

 leaves as " glabra vel subtus In nervis puberula " he apparently includes 

 fruiting specimens of Henry's No. 6754 which belongs to/, caha. Batalin*s 

 description of the flowers fits exactly Wilson's specimens from Pan-Ian- 

 shan under No. 2995 except that he describes the styles as pilose, while
