CRATAEGUS PROCERA, Saeg. 



Crataegus procera, n. sp. 



Glabrous with the exception of the hairs on the upper surface of the young leaves. Leaves 

 ovate, acuminate, rounded or abruptly cuneate at the broad entire base, finely often doubly serrate 

 above, with straight or incurved glandular teeth, and slightly divided into five or six pairs of small 

 acuminate spreading lobes ; about half grown when the flowers open and then very thin, dark 

 yellow-green, lustrous, and slightly hairy along the midribs above and pale below, and at maturity 

 thin but firm in texture, dark blue-green and lustrous on the upper surface, pale bluish green on 

 the lower surface, from 5 to 5.6 centimetres long and from 4 to 5 centimetres wide, with slender 

 midribs and thin obscure primary veins; petioles slender, slightly wing-margined at the apex, 

 glandular while young, with mostly deciduous glands, from 2.5 to 3 centimetres in length ; leaves 

 on vigorous shoots broadly ovate, often cordate at the base, more coarsely serrate, more deeply 

 lobed, and frequently 7 to 8 centimetres long and wide. Flowers from 2 to 2.2 centimetres in dia- 

 meter, on long slender pedicels, in small mostly five or six-flowered corymbs, the elongated lower 

 peduncles from the axils of upper leaves ; calyx-tube narrowly obconic, the lobes gradually nar- 

 rowed from wide bases, short, slender, acuminate, minutely and irregularly glandular-serrate usually 

 only above the middle, more or less tinged with rose color, reflexed after anthesis ; stamens ten ; 

 anthers pale pink ; styles three or four, surrounded at the base by a ring of long white hairs. 

 Fruit on long stout spreading or erect pedicels, in few-fruited clusters, crimson, slightly pruinose, 

 becoming lustrous, marked by large pale dots, subglobose but often rather broader than high, 

 from 1.2 to 1.4 centimetres in diameter, depressed at the insertion of the stalk; calyx prominent, 

 with a broad deep cavity gradually narrowed downward, pointed and tomentose in the bottom, 

 and small spreading and slightly incurved lobes dark red on the upper side ; flesh thin, sweet, 

 rather juicy, blood red when fully ripe ; nutlets three or four, gradually narrowed to the rounded 

 or acute ends, rounded and grooved or slightly ridged on the back, from 6 to 6.5 millimetres long 

 and about 4 millimetres wide. 



A tree up to 7 metres high, with a trunk sometimes 3.7 decimetres in diameter, with gray 

 scaly bark, long wide-spreading purplish branches, the lower drooping, the upper ascending and 

 forming a broad round-topped rather open head, and slender nearly straight branchlets light 

 orange-green and marked by pale lenticels when they first appear, becoming light chestnut-brown 

 and very lustrous in their first season and dull gray-brown the following year, and armed with 

 slender straight or slightly curved orange-brown or dark purple shining spines from 2 to 2.5 cen- 

 timetres long. Flowers appear during the last week of May. Fruit ripens from the middle to 

 the end of October.
