Crataegus seclusa n. sp. 



Glabrous with the exception of the hairs on the young leaves 

 and calyx-lobes. Leaves broadly ovate, rounded or occasionally 

 abruptly cuneate at the wide iDase, sharply doubly serrate with 

 straight glandular teeth, and slightly divided into broad acumin- 

 ate lobes; more than half -grown when the flowers open in the 

 last week of May and then thin, yellow-green, smooth and 

 slightly hairy above and glabrous and giaucescent below, and at 

 maturity thin, dark yellow-green and glabrous on the upper 

 surface, pale on the lower surface, 5 to 7 cm long and wide, with 

 stout midribs, and prominent primary veins extending obliquely 

 to the points of the lobes; petioles slender, narrowly wing-mar- 

 gined at the apex, slightly hairy on the upper side early in the sea- 

 son, soon becoming glabrous, occasionally glandular, 2 to 2.5 cm 

 in length. Flowers 1.5 cm in diameter, on long slender pedicels, 

 the lower peduncles from the axils of upper leaves; calyx-tube 

 narrowly obconic, the lobes gradually narrowed from the base, 

 short-acuminate, glandular-serrate, villose on the lower surface, 

 reflexed after anthesis ; stamens six to ten ; anthers dark red ; 

 styles three or four, surrounded at the base by a ring of white 

 tomentum. Fruit ripening at the end of September, on drooping 

 red pedicels, subglobose, orange-red, marked by small pale dots, 

 slightly pruinose, becoming lustrous, i cm in diameter ; calyx 

 little enlarged, with a broad, shallow cavity pointed in the bot- 

 tom, and spreading closely appressed persistent lobes ; flesh thin, 

 dry and mealy; nutlets three or four, rounded at the ends, 

 rather broader at the apex than at the base, ridged on the back 

 with a broad grooved ridge, 1.6 to 1.7 cm long and 3 to 4 mm 

 wide, the narrow hypostyle extending nearly to the base of the 

 nutlet. 



A shrub 5 to 6 m high, with stout stems covered with rough 

 dark brown bark, ascending branches, and slender glabrous.
