224 Eleventh Annual Report 



petioles 1-1.5 cm, (^-H inch) long, densely hairy above and smooth 

 beneath; flowers appear in May; fruit, wine or dark maroon color, 

 on stalks that curve upward, the stalks about the same length of 

 the petioles, nutlets globose, slightly longer than wide, 5.5-6 mm. 

 (1/5 inch) long, 5-5.5 mm. (1/5 inch) wide, covering white. 



This species may be distinguished from the preceding by the 

 relatively smaller leaves, many of which are entire or nearly so, by 

 the flowers appearing about two weeks earlier, by the nutlet being 

 smaller and the pits of the surface not so deep. 



Distribution. Delaware south along the Atlantic coast, west 

 through Pennsylvania to Kansas, Colorado and Utah. In Indiana 

 it is known only from Lake County near the Calumet River at 

 Millers. It is usually found in clumps on the dry wooded sand 

 dunes. Generally a shrub and rarely attaining a diameter of more 

 than 0.5 dm. (2 inches) and a height of 4 m. (13 feet). 



This species was reported for the State by Prof. Stanley Coulter 

 in the Proc. Ind. Acad. Science, 1900, page 143. The form reported 

 by Dr. Schneck as occurring on the ''rocky banks of Blue River" in 

 Crawford County, is the entire leaved form referred to under the 

 preceding species. 



The published records of the distribution are as follows: Lake 

 (Hill). 



Additional records are: Lake (Deam) and (Umbach). 



Economic uses. Too small and rare to be of any economic value. 



3. Celtis mississippiensis Bosc. Hackberry. Yellow Hack- 

 berry. 67. Bark on the lower part of the trunk of mature trees 

 covered with wart-like excresences, rarely somewhat irregularly fis- 

 sured, bark of the upper part of the trunk resembling that of the 

 beech; leaves of an ovate-lancolate type, narrower than those of 

 the preceding species, 4-10 cm. (13^-4 inches) long, entire or oc- 

 casionally with a few incurved teeth to about the middle of the 

 blade, smooth at maturity both above and below; petioles 0.5-1 cm. 

 iyi-Yi inch) long, glabrous or nearly so; flowering season April 

 or May; fruit orange red, on pedicels [about the length of the 

 petioles of the leaves; nutlet yellowish-white, globular, about 5 mm. 

 (1/5 inch) in diameter each way. 



Distribution. Southern Indiana south to Florida and west to 

 Missouri and Texas. In Indiana it is found only in the south- 

 western part where it is frequent or common along streams and in 

 the lowlands. It is inclined to grow scrubby and crooked. It is 

 medium sized and frequently becomes a half meter (18 inches) in 

 diameter.
