TREES OF NORTH AMERICA 



long slender pubescent pedicels, in drooping few-fruited clusters, obovoid, rounded at the 

 ends, bright cherry-red, lustrous, marked by occasional large pale dots, about ' long and 

 -|' in diameter; calyx prominent, with linear glandular-serrate closely appressed lobes 

 often deciduous before the fruit ripens; flesh thin, light yellow, juicy; nutlets 4 or usually 

 5, rounded, and deeply grooved on the back, dark brown, f ' long. 



A tree, 25-30 high, with a trunk a foot in diameter, spreading branches forming a 

 broad symmetrical head, and slender branchlets light green and villose when they first ap- 

 pear with long matted pale hairs, dull red-brown and pubescent in their first season, be- 

 coming glabrous the following year, and armed with occasional thin nearly straight bright 

 chestnut-brown shining spines usually about 1|' long. 



Distribution. Rich bottom-lands of the streams of Shannon County, southern Missouri. 



85. Crataegus lanuginosa Sarg. 



Leaves ovate to suborbicular, acute or rounded and short-pointed at apex, broadly 

 cuneate or rounded at the entire base, coarsely and sharply doubly serrate above with 

 glandular teeth, and often irregularly divided above the middle into short broad acute

lateral lobes, less than half grown when the flowers open during the last week of April 

 and then dark green and villose above and covered below with a thick coat of hoary tomen- 

 tum, and at maturity subcoriaceous, dark blue-green, lustrous and scabrate on the upper 

 surface, yellow-green and tomentose on the lower surface, 1%'-%' long, and I'-l^' wide, 

 with a thick midrib, and 3-5 pairs of stout primary veins extending obliquely to the point 

 of the lobes; petioles stout, tomentose, |'-f in length; leaves at the end of vigorous snoots 

 often broad-ovate, very coarsely glandular-serrate, rounded or truncate at base, and fre- 

 quently 3' long and wide. Flowers f ' in diameter, on short stout pedicels covered with 

 long matted pale hairs, in compact many-flowered hoary-tomentose corymbs, with large 

 glandular-serrate conspicuous bracts and bractlets persistent until the flowers open; calyx- 

 tube broadly obconic, hairy, the lobes short, broad, acute, glandular with minute stipitate 

 glands, densely villose on the outer surface and slightly villose on the inner surface; sta- 

 mens 20; anthers rose color; styles 5, surrounded at base by large tufts of snow-white hairs. 

 Fruit ripening at the end of October, on short tomentose erect pedicels, in few-fruited clus- 

 ters, subglobose to short-oblong, rounded and slightly hairy at the ends, \' in diameter: 

 calyx enlarged, with villose coarsely serrate usually erect spreading or incurved persistent 

 lobes bright red on the upper side near the base; flesh thin, orange color, dry and mealy; 

 nutlets 5, thin, rounded and very irregularly ridged on the back, about \' long.
