TREES AND SHRUBS. 143 



as long as the tube ; petals red in bud, becoming light pink when expanding and finally nearly white, broadly oval, rounded at the 

 apex and at the rounded or subcordate base abruptly contracted into a slender claw ; stamens one third shorter than the petals, 

 with purple anthers ; styles shorter than the stamens, villose at the lower third. Fruit subglobose, on slender villose pedicels 

 about 2 centimetres in length, with shallow cavities at the base and apex, crowned by the persistent tomentose calyx-lobes, about 

 2.5 centimetres in diameter, clothed near the base and the apex with the persistent tomeutum. 



A small, intricately branched tree, from 4 to 5 metres high, or often a shrub spreading into great thickets, with densely tomen- 

 tose branchlets, becoming glabrescent toward the end of their first year or sometimes not until the second year, and pale red- 

 brown or grayish brown. The bark of the trunk is light gray, peeling off in thin plates, exposing the cinnamon brown inner

This variety differs chiefly from the type in its smaller and much broader leaves not at all or only slightly lobed and densely 

 villose even at maturity, and in its often shrubby habit. It marks the southwestern limit of the range of Malus ioensis and of the 



The variation in Malus ioensis seems to be very wide. Specimens collected by B. F. Bush near Dodson, Missouri (Nos. 744, 

 746), and near Independence, Missouri (Nos. 754, 758, 759), approach the variety Palmeri, while Bush's specimens from Monteer, 

 Missouri (No. 6099), have the leaves only slightly pubescent, strongly lobed on vigorous shoots, oblong-ovate and only serrate on 

 weaker branches, thus approaching in stages Malus lancifolia; specimens similar to the last were collected by G. W. Letterman 

 near Allenton, Missouri, in 1883. Among the specimens collected in Wisconsin in 1893 by M. E. Gilbreth, J. G. Jack and A. B. 

 Seymour are some with quite glabrous leaves and nearly glabrous branchlets, but the shape of the leaves and of the fruits shows 

 that they belong to Malus ioensis. All these forms need further investigation and study based on more extensive material than
