 20. Crataegus inoompta. 



Glabrous. Leaves ovate to oval, acute or acuminate, rounded 

 or abruptly cuneate at the broad base, finely often doubly serrate, 

 with straight glandular teeth, and slightly divided usually only above 

 the middle into 3 or 4 pairs of short lobes; nearly half-grown when 

 the flowers open about the 20th of May and then thin, yellow-green, 

 lustrous above and rather paler below, and at maturity thick, dark 

 blue-green on the upper surface, pale bluish green on the lower sur- 

 face, 4-4.5 cm. long and 3.5-4 cm. wide, with slender midribs and 

 primary veins; petioles stout, slightly wing-margined at the apex, 

 glandular, with minute often persistent glands, 1.8-2.2 cm. in length; 

 leaves on vigorous shoots usually rounded or cordate at the base, 

 more coarsely serrate and more deeply lobed and often 5.5-6 cm. long 

 and nearly as br©ad. Flowers 2-2.3 cm. in diameter, on long slender 

 pedicels, in wide 4-7-flowered corymbs, with oblong-obovate to 

 linear glandular rose-colored bracts and bracelets often persistent 

 until the petals fall, the long lower peduncles from the axils of upper 

 leaves; calyx-tube broadly obconic, the lobes separated by wide sin- 

 uses, short, acuminate, entire or irregularly and minutely dentate 

 near the middle, reflexed after anthesis; stamens 20; anthers pale 

 yellow; styles 2 or 3, usually 3. Fruit ripening in October, on long 

 slender drooping pedicels, subglobose, or often rather broader than 

 high, dull red, pruinose, marked by large pale dots, about 1 cm. in 

 diameter; calyx prominent, with a short tube, a wide deep cavity 

 broad in the bottom, and elongated reflexed persistent lobes; flesh 

 thin, green, dry and hard; nutlets usually 3, rounded at the ends, 

 rounded and ridged on the back, with a broad deeply grooved ridge, 

 about 5 mm. long and 4 mm. wide. 



A slender shrub 1-2 m. high, with thin stems covered with dark 

 scaly bark and spreading into large thickets, and slender zigzag 

 branchlets dark orange-green and marked by pale lenticels when they 

 first appear, becoming dark red-brown in their first season and dull 

 reddish brown the following year, and armed with many stout straight 

 or slightly curved dark chestnut brown shining spines 3.5-5 cm. long, 

 and persistent and very numerous on old stems.
