serrate above with rounded teeth, glandular with bright red glands, and divided above the 

 middle into short acute lobes, nearly fully grown when the flowers open at the end of March, 

 and then glabrous with the exception of a few short pale hairs on the two surfaces near the 

 base of the midrib, and at maturity thin and firm in texture, bright yellow-green and lus- 

 trous above, pale below, glabrous, I'-li' long, and f'-l' wide, with a slender midrib, and 

 thin primary veins extending very obliquely to the point of the lobes; turning y el low r , orange, 

 or brown in the autumn; petioles slender, broadly wing-margined above the middle, con- 

 spicuously glandular, sparingly villose early in the season, becoming nearly glabrous, |'-f ' 

 in length. Flowers about f ' in diameter, on short villose pedicels, in simple 3-6-flowered 

 corymbs; calyx-tube broadly obconic, hairy near the base with scattered pale hairs, gla- 

 brous above, the lobes broad, acuminate, glandular-serrate, glabrous on the outer, pilose 

 on the inner surface; stamens 20; anthers pale purple; styles 3-5, surrounded at base by 

 small tufts of white hairs. Fruit ripening and falling late in August and early in September, 

 on stout pedicels, usually in 1 or 2-fruited clusters, obovoid, dark orange-colored, with a 

 red cheek, |'-|'' long, nearly \' in diameter; calyx enlarged, the lobes coarsely glandular- 

 serrate, puberulous on the upper surface, closely appressed; flesh soft and yellow; nutlets 

 3-5, obtuse and rounded at the ends, rounded and slightly ridged on the back, about f ' 

 long. 



A tree, sometimes 30 high, with a trunk 10'-12' in diameter, covered with dark gray or 

 brownish bark, crooked horizontal or ascending branches forming a broad irregular head, 

 and stout often contorted branchlets villose when they first appear, soon glabrous, dull 

 reddish brown to ashy gray, and armed with slender straight spines \'-\' long. 



Distribution. Sandy soil near Bristol, Liberty County, Florida. 



122. Crataegus ignava Beadl. 



Leaves obovate to ovate, acute, gradually narrowed from near the middle to the concave- 

 cuneate glandular base, sharply often doubly serrate above with glandular teeth, and usu- 

 ally divided tow y ard the apex into short acute lobes, nearly fully grown when the flowers

open at the end of April, and then membranaceous, glabrous with the exception of a few 

 hairs on the midrib above and on the midrib and slender veins below, and at maturity sub- 

 coriaceous, bright green and lustrous on the upper surface, pale and still hairy on the lower 

 surface, l|'-2' long, and \'-\\' wide; turning in the autumn yellow and brown sometimes 

 flushed with red; petioles slender, wing-margined at the apex, glandular, \'-\' in length. 

 Flowers about f ' in diameter, on slender glabrous pedicels, in 3-6-flowered simple corymbs,
