CRATAEGUS LIMAEIA, Sarg. 



(Molles.) 

 Crataegus limaria, n. sp. 



Leaves ovate, acute, concave-cuneate or rounded at the base, coarsely often doubly serrate with 

 straight broad glandular teeth, and slightly divided into three or four pairs of small acute lateral 

 lobes ; not more than one quarter grown when the flowers open early in April and then thin, yellow- 

 green and covered above with short white hairs and thickly coated below with hoary tomentum, and 

 at maturity thin, light green and scabrate on the upper surface, pale and tomentose on the lower 

 surface, from 6 to 8 centimetres long and from 4 to 7 centimetres wide, with stout midribs and thin 

 primary veins ; petioles slender, slightly wing-margined at the apex, covered at first with long 

 matted white hairs, villose through the season, from 2.5 to 3.5 centimetres in length ; leaves on 

 vigorous shoots broadly ovate, rounded or cordate at the wide base, more deeply lobed and often 

 from 9 to 10 centimetres long and broad. Flowers from 2 to 2.2 centimetres in diameter, on 

 long slender pedicels coated with matted white hairs, in compact fifteen- to twenty-flowered 

 corymbs with conspicuous oblong-obovate acuminate glandular-serrate villose bracts and bractlets 

 persistent until the flowers open, the lower peduncles from the axils of upper leaves ; calyx-tube 

 broadly obconic, thickly covered with white hairs, the lobes gradually narrowed from the base, 

 wide, acuminate, laciniately glandular-serrate, villose, reflexed after anthesis; stamens twenty; 

 anthers white ; styles three to five, surrounded at the base by a narrow ring of pale tomentum. 

 Fruit ripening in October, on long stout erect or spread-hairy pedicels, in few-fruited clusters, oval 

 to ovate or short-oblong, rounded at the apex, truncate at the base, crimson, lustrous, marked by 

 large pale dots, villose especially at the ends, from 1.2 to 1.5 centimetres in diameter; calyx 

 prominent, with a long villose tube, a broad deep cavity tomentose in the bottom and erect villose 

 persistent lobes dark red on the upper surface below the middle, their tips slightly spreading or 

 incurved ; flesh thick, yellow, dry and mealy ; nutlets from 3 to 5, narrowed and rounded at the 

 apex, rounded at the broad base, slightly grooved on the back, from 6.5 to 7 millimetres long and 

 from 4 to 4.5 millimetres wide, the narrow hypostyle extending nearly to the base of the nutlet. 



A tree, often 10 metres high, with a tall trunk from 2 to 3 decimetres in diameter, covered with 

 dark scaly bark, stout ascending branches forming a narrow irregular head, and slender zigzag 

 branchlets thickly coated when they first appear with long white hairs, light orange-brown, lustrous, 

 pubescent, and marked by pale lenticels at the end of their first season, dull gray-brown and 

 glabrous the following year, and armed with slender straight or slightly curved purple ulti- 

 mately ashy gray spines from 5 to 6 centimetres long.
