 3. Crataegus bona n. sp. 



Leaves ovate-oblong or occasionally rhombic, acuminate, usually 

 full and rounded or rarely acute or truncate, or on vigorous shoots 

 sometimes subcordate, at the entire base, finely doubly serrate above, 

 with straight glandular teeth, and often slightly divided into 2 or 3 

 pairs of small acute lateral lobes, pale reddish-bronze when they unfold, 

 more than half-grown when the flowers open about the 20th of May, 

 and then membranaceous and glabrous with the exception of a few 

 scattered caducous hairs on the base of the upper side of the midribs, 

 and at maturity thin, dark bluish-green on the upper, pale on the lower 

 surface, 3.5-4.5 cm. long and 2.5-3 cm. wide, with thin midribs and 

 slender veins extending obliquely to the points of the lobes; petioles 

 very slender, obscurely grooved on the upper side, slightly wing-mar- 

 gined at the apex, glandular at first, with scattered stipitate caducous 

 glands, 2-2.5 cm. in length; stipules narrow, acuminate, falcate, con- 

 spicuously glandular, caducous. Flowers 1.6-1.8 cm. in diameter, on 

 short slender glabrous pedicels, in small very compact 2-6-flowered 

 simple corymbs, with comparatively large oblong-obovate to linear 

 glandular caducous bracts and bractlets; calyx-tube broadly obconic, 

 the lobes separated by wide sinuses, gradually narrowed from a broad 

 base, short, acute or acuminate, entire or rarely obscm-ely toothed, 

 tinged with red at the apex; stamens 20; anthers pink; styles 3-5, 

 usually 4, surrounded at the base by a narrow ring of short pale hairs. 

 Fruit ripening early in October, on short erect pedicels, visually in 1-4- 

 fruited clusters, depressed-globose, often angular, sometimes swollen 

 and acutely mamihate round the middle, slightly concave or flattened 

 at the apex, retuse at the base, scarlet, frequently dark olive-green or 

 spotted with russet or orange toward the apex, covered with a glaucous 

 bloom, 1.2-1.4 cm. in diameter and 1-1.1 cm. high; calyx enlarged, ^ith 

 a short tube, a broad deep cavity and spreading and closely appressed 

 lobes red on the upper side below the middle and mostly persistent on 

 the ripe fruit ; flesh thin, firm, yellow or greenish-yellow, dry and mealy ; 

 nutlets usually 4. 



A shrub, sometimes 3-4 m. high, with numerous ascending to semi- 

 erect slender flexuose stems covered with dark gray or nearly black
