Description

Small tree or shrub, 3‒5 m high, rarely 8 m. Branches terete, pubescent when young, glabrescent. Leaves petiolate, petiole ca 0.8‒1.9 cm long, densely lanuginous. Lamina 3.4‒6.8 × 2.3‒3.6 cm, oval to ovate, base rounded, cuneate or cordate, equilateral, apex acuminate or obtuse, margin crenate to serrulate, blade puberulous when young, then abaxially glabrescent, usually 3‒5 divided. Inflorescence umbelliform corymb, with 3‒6 flowers. Pedicel ca 1.7‒2.0 cm long, puberulous. Hypanthium lanuginous. Sepals triangular, densely puberulous, caducous, rarely persistent. Petals ca 0.7‒0.9 × 0.4‒0.6 cm, white, obovate or oblong. Stamens 20‒25, unequal. Styles 3‒5, longer than stamens, glabrous. Pome ca 0.6‒0.8 cm in diameter, subglobose, yellow to red. Carpopodium ca 2.3‒2.8 cm long, puberulous.

Phenology

Flowers from April to May. Mature fruits in September.

Habitat

Terrestrial, seasonally green, growing in forests on slopes or loess hills; 1500‒3900 m a.s.l.

Distribution

China (Inner Mongolia, Ningxia, Qinghai, Shaanxi, Gansu, Sichuan, Yunnan, Tibet) ( Fig. 31 View Fig ).

Chromosome numbers

2n = 34, 51.

Note

There are plentiful morphological variations within this species. Varieties that have been defined on the basis of a few characters and locations are unjustified because such unique phenotypic characters have probably been affected by the environment. Therefore, three new synonyms are proposed in this study ( Malus transitoria var. glabrescens , M. transitoria var. calycomeles , and M. transitoria var. centralasiatica ).

The vertical vicariance of Malus kansuensis (distribution below 3000 m), M. toringoides (2600‒3050 m) and M. transitoria (above 3000 m) is very remarkable, and there are no obvious reproductive barriers between them.As a consequence, hybrids that show characters of both parents could be found in the contact zones; for example, the specimens from Maerkang (Sichuan, China) exhibit continuous morphological variation between M. transitoria and M. toringoides .
