CRATAEGUS INC^DUA, Sajsg. 



(Punctatae.) 

 Crataegus inc^edua, n. sj). 



Leaves oblong-obovate to oval, acuminate or occasionally rounded at the apex, gradually nar- 

 rowed to the long concave-cuneate entire base, and coarsely doubly serrate above, with straight 

 or incurved glandular teeth ; strigose above when they unfold and covered below with soft white 

 hairs most abundant on the midribs and veins, more than half grown when the flowers open, and 

 then thin, yellow-green, smooth, lustrous, and almost glabrous on the upper surface, and at 

 maturity thin but firm in texture, dark yellow-green and very lustrous above, pale and villose 

 below along the midribs and obscure primary veins, from 5 to 6 centimetres long and from 3 to 

 3.5 centimetres wide ; petioles slender, narrowly wing-margined often nearly to the base, at first 

 densely villose, becoming glabrous iu the autumn, from 8 to 10 millimetres in length ; leaves on 

 vigorous shoots thicker, very coarsely serrate, not lobed, from 7 to 8 centimetres long and from 

 6 to 7 centimetres wide, with stout broad-winged petioles and narrow acuminate falcate glandular 

 stipules. Flowers from 1.4 to 1.5 centimetres in diameter, on long slender pedicels, in wide lax 

 mostly from fifteen to twenty-flowered hairy corymbs, with narrow-lanceolate to linear acuminate 

 glandular bracts and bractlets fading brown and often persistent until the flowers open, the lower 

 peduncle from the axil of an upper leaf ; calyx-tube narrowly obconic, thickly coated like the 

 pedicels with long glistening white hairs, the lobes long, slender, acuminate, nearly glabrous on 

 the outer surface, villose on the inner surface, reflexed after anthesis ; stamens from ten to fifteen ; 

 anthers large, pale yellow j styles two or three, surrounded at the base by a narrow ring of pale 

 hairs. Fruit on long slender stems, in wide many-fruited drooping clusters, short-oblong, full and 

 rounded at the ends, yellowish red marked by large pale dots, from 9 to 10 millimetres in diame- 

 ter ; calyx little enlarged, with a deep narrow cavity, and spreading and often reflexed usually 

 persistent lobes villose on the upper surface ; flesh thin, dry, and hard ; nutlets usually two, 

 rounded and obtuse at the ends, rounded and slightly grooved or ridged on the back, with a low 

 grooved ridge, from 6 to 7 millimetres long and from 4 to 4.5 millimetres wide. 



A tree, from 5 to 7 metres high, with a tall trunk from 1 to 1.5 decimetres in diameter, and 

 stout slightly zigzag branchlets covered when they first appear with matted white hairs, becoming 

 verrucose, light chestnut-brown, rather lustrous and marked by large pale lenticels in their first 

 season and light gray-brown the following year, and armed with numerous slender nearly straight 

 bright chestnut-brown shining spines from 4 to 7 centimetres long. Flowers appear from the 

 10th to the middle of May. Fruit ripens early in October. 



Borders of small streams in dry gravelly soil, near Monteer, Shannon County, Missouri, B. F. 

 Bush, May 16, 1901 (Nos. 501 and 510), May 13 and October 5, 1905 (No. 9 B type), also 

 May and October, 1905 (Nos. 9, 9 A, 9 D, 9 E, 9 F, 9 H, 9 1, 9 K, 9 L). 



Of the species of Punctatae previously described only Crataegus Lettermani, Sargent, has ten stamens with yellow 

 anthers, and that central Missouri species differs from Crataegus inccedua in its more obovate often deeply lobed 

 scabrate leaves hoary-tomentose below while young, in its fewer-flowered more compact corymbs, and in its ovate or 

 subglobose fruits on short pubescent peduncles.
