I found them glabrous; in these specimens the young leaves are densely 

 villose on the whole under side and the same pubescence is present in Pur- 

 dom*s specimens from western Kansu, which are in young fruit; the pu- 

 bescence never disappears entirely and in Wilson's fruiting specimens under 

 4115 from Pan-lan-shan and Tachien-lu the mature leaves show more or 

 less pubescence beneath, at least on the midrib and the veins.

Mains Komaroviii is closely related to M, kansucnsis and similar to 

 its form calvay but is easily distinguished by the short pedicels of the fruit 

 which are only 1-1.5 cm. long (2-3.5 in M. kansiiensis), by the cordate or 

 subcordate base of the more deeply lobed leaves, the sinus of the lower 

 lobes reaching often more than halfway to the middle, and by the oblong- 

 ovate gradually acuminate spreading or often slightly recurved lower lobes 

 -provided usually with a small basal lobe, while in M. kansuensis the lower 

 lobes are triangular-ovate and abruptly short-acuminate without basal 

 lobes. The resemblance of the leaves to those of certain Crataegus has led 

 Komarov in the absence of mature fruit to place this plant in the genus 

 Crataegus, but even before examining the structure of the ovary the race- 

 mose inflorescence shows at a glance that it is not a Crataegus. 



As the first specific name given to this plant is a still-born name, the later 

 valid specific name has to be used for the new combination under Malus. 



Malus honanensis, sp. nov. 



Frutex (vcrisimiliter) ; ramuli satis graciles, initio laxe floccoso-tomentosi, 

 cito glabri, rubro-brunnei, nitiduli; gemmae juveniles (medio Junio) pe- 

 rulis paucis rubro-brunneis extus glabris margine villosis. Folia late ovata, 

 rarissime oblongo-ovata, vel orbiculari-ovata, acuta, basi truncata vel ro- 

 tundata, intcrdum subcordata, 4-7 era, longa et 3.5-6.5 cm. lata, utrinque 

 lobis 2-5 apicem versus decrescentibus brevibus late ovatis acutis vel 

 obtusiusculis instructa, toto margine subsimpliciter argute serrulata vel 

 intcrdum crenato-serrulata, initio utrinque laxe villoso-tomentosa, supra 



^ Nakai figures the fruit erroneously with a persistent calyx, but the calyx is finally decidu- 

 ous, though it remains on the immature fruit a long time together with the remnants of the 

 stamens and the styles.
