Pulaski County, along Peak Creek on Peak Mountain, J. K. Small, July 16, 1892. Fayette 

 County, Ohio, Pyle, July 3-8, 1905. Illinois: Wolf Lake, May, 1880 (all in herb. Carnegie Mus.) : 

 Missouri, Jackson County, near Independence, B. F. Bush, May 30 and June 10, 1894 (Nos. 

 281, 284), near Courtney, May 23, 1894 (No. 283), April 29, 1906-10 (Nos. 283, 3869, 6426), 

 (all in herb. Arnold Arboretum). 



Malus lancifolia has usually been confounded with Mains angustifolia, which is readily distinguished by its oblong 

 more crenately serrate and usually more coriaceous leaves cuneate at the base and rounded at the apex, at least those 

 on the flowering shoots, by the broader and shorter calyx-lobes, by the pubescence only on the lower third of the style, 

 by the form of the petals which are more gradually narrowed into the claws, and by the globose-ovoid, not depressed-

> Malus coronaria Miller and the allied species, all natives of eastern North America, form a very distinct group of the genus 

 Malus which may be designated as Coronarice, characterized by leaves conduplicate in the bud and more or less lobed at least on 

 vigorous shoots, by the persistent calyx and by the red or reddish anthers and the free apex of the core of the fruit. By the per- 

 sistent calyx they are easily distinguished from Malus fusca Rafinesque of northwestern North America, and from Malus Toringo 

 and its allies from eastern Asia, which also have the leaves conduplicate in the bud with a tendency to become lobed ; by the con- 

 duplicate leaves and by the tendency to lobing the Coronarice are distinguished from all other species of Malus with a persist- 

 ent calyx, which have the leaves convolute in the bud and always unlobed. The Coronaria,, to which belong the two new species 

 here described, Malus coronaria Miller, the type of the group, Malus angustifolia Michaux, and Malus ioensis Britton, are very 

 variable and need more thorough study, but with the material at hand it is impossible to obtain a clear conception of the variation 

 and the range of the different species. Most of the forms are not yet in cultivation and are only incompletely represented in 

 herl a pa t 1 ly the fruits, which apparently present some good characters. I venture, however, to describe the following 

 varieties, of whose relationship there does not seem to be any doubt. 

 Malus coronaria var. Hoopesh, n. var. 



This differs from the type chiefly in its pubescent calyx, in the oval to elliptic, not or only slightly lobed leaves, and by the 

 larger fruit measuring about 5 centimetres in diameter. This variety is only known in cultivation. It was received at the Ar- 

 nold Arboretum from Iloopes Brothers & Thomas of West Chester, Pennsylvania, in 1876, and has grown into a large tree. The 

 only presumably wild specimen I have seen approaching this variety in its slightly villose calyx is one from Wheeling, West 

 Virginia, G. Guttenberg, May 7, 1878 (in herb. Carnegie Mus.). 



the base, crenately serrate or, on vigorous shoots, doubly serrate or rarely slightly lobed ; when they unfold sparingly hairy on 

 the upper surface, soon becoming quite glabrous, yellowish green and covered below with a close whitish tomentum more or less 

 persistent until maturity, at least on the veins, from 3 to 6 centimetres long and from 1.5 to 3 centimetres broad ; petioles tomen- 

 tose, from 1 to 1.5 centimetres in length. Flowers about 3 centimetres in diameter on tomentose pedicels in three- to five-flow- 

 ered umbel-like racemes ; calyx tomentose on the outer surface, the lobes narrowly triangular, ovate, attenuated into a glabrous 

 muero about as long as the tube ; petals broadly oval or obovate, rounded at the apex, narrowed at the base into a long claw, 

 about 1.5 centimetres long and 1 centimetre broad ; stamens about half as long as the petals, with purple anthers, shorter than the 

 styles or as long. Fruit subglobose, green at maturity, only very slightly covered with an exudation, from 2.5 to 3 centimetres in 

 diameter. 



A small slender tree, from 3 to 5 metres high, with stems covered like the spiny zigzag branches with dark gray-brown bark 

 exfoliating in thin plates, exposing the orange or cinnamon-colored inner bark, and stout branchlets densely tomentose when they 

 first appear, becoming glabrous or nearly so at the end of their first season and then reddish or gray-brown. Winter-buds small, 

 with grayish pubescent scales. 



Missouri : Jasper County, near Webb City, along small streams, E. J. Palmer, September 22, 1901, and April 28, 1909 (No. 

 1795). 



This variety differs from the type chiefly in its smaller oblong more thinly pubescent leaves which are rounded at the apex, 

 those of the flowering shoots being only crenately serrate and not lobed. It is named for Mr. E. J. Palmer of Webb City, Mis- 

 souri, who has for several years been actively engaged in collecting and studying the plants of the interesting flora of southwest 



Malus ioensis var. texana, pi. var. 



Leaves oval, rarely oblong, irregularly or doubly serrate, on vigorous shoots sometimes ovate or broadly ovate and slightly 

 lobed, or obovate and irregularly doubly serrate, acute or rarely rounded at the apex, and cuneate or rounded at the base; when 

 unfolding slightly floecose above, soon becoming quite glabrous except on the midrib, yellowish green, grayish-tomentose beneath, 

 from 3 to 6 centimetres long and from 1.5 to nearly 4 centimetres broad ; petioles densely tomentose, from 1 to 1 5 centimetres 

 m length ; stipules filiform, villose, about 5 millimetres long. Flowers about 3 centimetres in diameter, on tomentose pedicels 

 from 2 to 2.5 centimetres long in two- to four-flowered umbels ; calyx densely white-tomentose, the lobes triangular-ovate, about
