TREES AND SHRUBS. 



PRUNUS AEKANSANA, Sarg. 



Prtjnus (Prunophora) i 



Leaves ovate to elliptical or obovate, abruptly long-pointed and acuminate at the apex, rounded 

 or rarely cuneate and often glandular at the base, and finely doubly serrate, with slender apiculate 

 straight or slightly incurved teeth ; at maturity thick, dark yellow-green, glabrous and lustrous on 

 the upper surface, paler and sparingly covered on the lower surface with long soft white hairs most 

 abundant on the prominent midribs and primary veins and on the numerous conspicuous reticu- 

 late veinlets, from 4.5 to 9 centimetres long and from 3 to 4.5 centimetres wide ; petioles stout, 

 pubescent or puberulous, glandular at the apex, with large dark glands, or eglandular, from 1 to 

 1.5 centimetres in length. Flowers appearing before the leaves, 2.5 centimetres in diameter, on 

 slender glabrous pedicels in three- or four-flowered sessile umbels; calyx-tube narrowly obconic, 

 glabrous, the lobes short, rounded and lacerate at the apex, ciliate and sparingly glandular, with 

 small sessile glands on the margins, puberulous on the outer surface, hoary-tomentose on the 

 inner surface, reflexed after anthesis; petals white, ovate, rounded at the narrow apex, crenu- 

 late, gradually narrowed below into a short claw, about three times as long as the calyx-lobes; 

 style longer than the stamens. Fruit short-oblong, rounded at the ends, dark purplish red with a 

 slight glaucous bloom and thick succulent flesh, from 3 to 3.5 centimetres long and from 2.6 to 3 

 centimetres in length ; stone oblong, much compressed, un symmetrical, narrowed and rounded at 

 the base, acute and often short-pointed at the apex, ridged on the rounded dorsal edge, with a 

 broad thin ridge, thin, less rounded and grooved on the ventral edge, from 2.7 to 2.9 centimetres 

 long and from 1.2 to 1.3 centimetres wide. 



A tree, from 7 to 8 metres high, with a trunk sometimes 3 decimetres in diameter, stout 

 branches forming an open irregular head, and slender glabrous branchlets light orange-brown, 

 very lustrous and marked by dark lenticels during their first winter and dull gray-brown the 

 following year. Winter-buds ovate, acute, glabrous, from 4 to 5 millimetres long. Flowers from 

 the middle to the end of March. Fruit ripens at the end of June. 



Rich woods, Prescott, Nevada County, Arkansas, J. H. Kellogg, March 23 and June 24, 1910 (Nos. 

 243 type and 244), Fulton, Hempstead County, Arkansas, -/. H. Kellogg, March 21 and August 30, 

 1910 (No. 242, with later ripening fruit). Specimens collected by Kellogg at Prescott on March 

 26 and June 25, 1910 (No. 245), with more pubescent leaves, slightly villose pedicels, globose, 

 bright red fruit not more than 2.5 centimetres in diameter and a less compressed stone, should per- 

 haps be considered a form of this species. 



Prunus arkansana seems to be well distinguished from the last species from the same region by its thicker more 

 conspicuously reticulate leaves, the character of the pubescence on their lower surface, in the shape of the stone of the 

 fruit and the color of the branchlets. 1 



C. S. S. 



1 The following shrubby species may be characterized: — 

 Prunus (Frunophora) venulosa, n. sp. 



Leaves lanceolate, gradually or abruptly narrowed and acuminate at the apex, narrowed and rounded or cuneate at the base, 

 and finely often doubly serrate, with slightly incurved or straight apiculate teeth ; at maturity conspicuously reticulate-venulose, 

 thin, dark yellow-green, smooth and lustrous on the upper surface, pale below, from 5 to 6 centimetres long and from 2 to 2.5 

 centimetres wide, with slender midribs and primary veins covered on their lower surface with short, white erect hairs ; petioles 

 slender, dark red, pubescent, glandular near the apex, from 1 to 1.2 centimetres in length. Flowers appearing before the leaves, 

 from 6 to 7 millimetres in diameter, on slender sparingly villose pedicels from 4 to 5 millimetres long, in mostly three- or four-
