Missouri: B. F. Bush, Campbell, Dnnklin County, April 22, 1912 (Nos. 6630, type, 6631), April IS, 1912 (Nos 

 Bush and C. S. Sargent, October 6, 1912 (No. 6850). 



This variety resembles somewhat M. coronaria Miller, but is easily distinguished by its pub. mmm, hy He I 

 leaves, and by the lobed ovate leaves of the shoots, which are pubescent below at maturity. It is more marly 

 sis, var. Palmeri Rehder, bnt differs chiefly in its shrubby habit, smaller leaves 8 

 and 6631 differ from the 



Malus ioensis, var. creniserrata, n. var. 



Leaves elliptic-ovate to oblong-ovate, rounded 

 smaller leaves nearly entire, those of vi 

 metres broad, those of the shoots often 



above, light green beneath, those of the flowering branchlets glabrous or nearly so except 

 tomentose beneath when unfolding, at maturity thinly villose; petioles from 5 to 1! 

 Flowers from three to five, on villose pedicels about 2 centimetres in length ; calyx-tube 



thinly so; calyx-lobes lanceolate, slightly longer than the tube, tomentose on both surfaces, ending in a^ glabrous 

 petals oval, abruptly contracted into a slender claw from 3 to 4 millimetres long, " 

 and from 1 to 1.2 centimetres broad ; stamens about one-third shorter than the petals; styles slightly shorter than the stamens, 

 villose below the middle, connate for about one-third of their length. Fruit depressed-globose, from 2 to 2.5 centimetres high 

 and from 2.5 to 3 centimetres in diameter, cavities at base and apex rather shallow. 



A tree, with slender spineless branches villose when young. 



Louisiana: Pineville, La Salle Parish, C. S. Sargent, April 3, 1885 (type), R. S. Cocks, September, 1912; Crowley, Acadia 

 Parish, /. G. Haupt, September, 1912 (Nos. 1 and 2). 



The leaves of the flowering branches in shape and texture resemble those of M. lancifolia Rehder, but they are pubescent be- 

 neath, at least on the veins, and have densely villose petioles; and the tomentose calyx and the generally ovate leaves of the 

 shoots which are thinly villose below at maturity readily distinguish it from M. lancxfoha. The broad, not lobed, only doubly 

 serrate leaves of the shoots resemble those of M. ioensis, var. texana, but they are larger and less densely tomentose.
