TREES AND SHRUBS. 



wide, with slender midribs and obscure primary veins ; petioles slender, wing- 

 on vigorous shoots broadly ovate, acute at the apex and cuneate at the base, 

 slightly or deeply three-lobed, and often from 1.8 to 2 centimetres long and 

 :, foliaceous, coarsely glandular-serrate, from 2 to 3 millimetres in length, persistent. Flowers 

 imeter, on slender pedicels, in one- or very rarely near the ends of the branches in two- or three- 

 flowered corymbs ; calyx-tube broadly obconic, the lobes oblong, abruptly narrowed and apiculate at the apex, finely glandular- 

 serrate near the middle, slightly villose on the inner surface, reflexed after anthesis ; stamens twenty ; anthers dark rose color ; 

 styles Ave. Fruit on slender erect or spreading pedicels, subglobose to short-oblong, cherry-red, from 8 to 10 millimetres in 

 diameter ; calyx prominent with a wide deep cavity pointed and pubescent in the bottom and erect incurved coarsely serrate 

 lobes ; nutlets five, rounded at the ends, broader at the apex than at the base, rounded and slightly grooved on the back, about 

 5 millimetres long and from 3 to 3.5 millimetres wide, the broad conspicuous hypostyle extending nearly to the base of the nutlet. 

 A shrub, from 1 to 2 metres high, with slender ashy-gray stems, and slender conspicuously zigzag branchlets light orange-brown 

 when they first appear, becoming bright chestnut-brown and lustrous in their second season and dull gray-brown the following 

 year, and armed with numerous slender nearly straight chestnut-brown shining spines from 1.5 to 3 centimetres long. Flowers 

 the middle of March. Fruit ripens the middle of July.

This beautiful little shrub is of considerable interest as the only dwarf species of the JEstivales Group now known. The soli- 

 tary flowers, too, are unusual in the plants of this group. 



Crataegus amicalis, n. sp. (Virides.) 



Leaves oblong-obovate, broad and rounded or abruptly narrowed and acute at the apex, cuneate and often unsymmetrical at 

 the base, and sharply doubly serrate above the middle with straight glandular teeth; nearly fully grown when the flowers open 

 and then pale yellow-green and roughened above by short white hairs and glaucescent below with villose midribs and veins, and 

 at maturity thick and firm in texture, yellow-green, smooth, lustrous and glabrous on the upper surface, paler and slightly hairy 

 on the prominent midribs and primary veins on the lower surface, from 2.5 to 3 centimetres long and from 2 to 2.4 centimetres 

 wide ; petioles stout, wing-margined to below the middle, more or less thickly covered with pale hairs early in the season, be- 

 coming glabrous, about 1 centimetre in length ; leaves on vigorous shoots oval to oblong-obovate, acute, sometimes slightly lobed 

 above the middle, more coarsely serrate, and sometimes from 4 to 5 centimetres long and 3 centimetres wide. Flowers from 1.6 

 to 1.8 centimetres in diameter, on very slender villose pedicels, in wide from five- to twelve-flowered hairy corymbs ; calyx-tube 

 broadly obconic, villose at the base, the lobes short, gradually narrowed from wide bases, acuminate, entire or minutely glandular- 

 dentate, slightly hairy on the outer surface, villose on the inner surface, reflexed after anthesis ; stamens twenty; anthers yellow; 

 styles five, surrounded at the base by a narrow ring of yellowish white hairs. Fruit on slender drooping pedicels, subglobose, 

 dull red, from 6 to 8 millimetres in diameter ; calyx prominent with a deep broad cavity wide in the bottom, and spreading lobes ; 

 flesh dry and hard; nutlets five, rounded at the ends, rather broader at the apex than at the base, irregularly ridged on the back 

 with a narrow low deeply grooved ridge, from 5 to 6 millimetres long and 3 millimetres wide, the broad conspicuous hypostvle 

 extending to below the middle of the nutlet. 



A tree, from 5 to 8 metres high, with a trunk sometimes 2.5 decimetres in diameter, and slender slightly zigzag branchlets 

 covered when they first appear with long matted white hairs, dull chestnut-brown and nearly glabrous at the end of their first 

 season and gray-brown in their second year, and armed with occasional slender straight ashy-gray spines from 2 to 3 centimetres 

 in length. Flowers late in April. Fruit ripens in October.

Crataegus velutina, n. sp. ( Virides.) 



Leaves ovate to obovate, acute or rounded at the apex, gradually narrowed and cuneate at the entire base, and sharply often 

 doubly serrate with straight glandular teeth ; more than half grown when the flowers open and then dark yellow-green and cov- 

 ered above by short white hairs most abundant on the midribs and veins, and coated below with hoary pubescence, and at maturity 

 smooth, lustrous and glabrous on the upper surface and covered below with matted white hairs, from 4 to 5 centimetres long and 

 from 2.5 to 3 centimetres wide, with thin midribs and primary veins ; petioles slender, thickly covered early in the season with 

 matted pale hairs, becoming glabrous ; leaves on vigorous shoots ovate, rounded or broadly cuneate at the base, acute at the apex, 

 coarsely serrate, and often from 4.5 to 5 centimetres long and from 3.5 to 5 centimetres wide. Flowers 1.2 centimetres in diameter] 

 on slender villose pedicels, in mostly from seven- to twelve-flowered hairy corymbs ; calyx-tube narrowly obconic, villose, the lobes 

 gradually narrowed from broad bases, short, acute, entire, slightly villose; stamens twenty; anthers canary yellow ; styles five. 

 *ruit on slender drooping glabrous or nearly glabrous pedicels, subglobose, orange-red, marked by small pale dots, from 6 to 7 

 millimetres in diameter; calyx prominent, with a deep narrow cavity pointed in the bottom, and closely appressed lobes; flesh 

 thin yellow dry and mealy; nutlets five, acute at the base, rounded at the apex, ridged on the back with a low grooved ridge, 

 about 4 millimetres long and 2.3 millimetres wide, the broad hypostyle extending to below the middle of the nutlet. 



A tree from 2 to 6 metres high, with a trunk sometimes 2 decimetres in diameter, covered with dark rough scaly bark, and 

 slender slightly zigzag branchlets hoary tomentose when they first appear, light red-brown, lustrous and marked by pale lenticels 

 at the end of their first season and ashy-gray the following year, and armed with slender nearly straight chestnut-brown spines 

 irom A to 3.5 centimetres in length. Flowers the end of April. Fruit ripens in October.
