The writer is not able to separate the two forms in our area, and believes 

 that all belong either to Celtis pumila or to the new variety. 



3. Celtis mississippiensis Bosc. (Celtis laevigata Willdenow)- 

 SUGARBERRY. HACKBERRY. Plate 63. Medium sized trees with the 

 bark of the trunk of large trees irregularly covered with wart-like 

 excrescences, rarely somewhat irregularly fissured, bark of the upper 

 part of trunk and larger branches resembling that of the beech; leaves 

 of an ovate-lanceolate type, as a whole narrower than the preceding 

 species; on petioles 5-12 mm. long, blades of fruiting twigs 4-8 cm. long, 

 usually rounded at the base, sometimes oblique, slightly cordate or 

 somewhat narrowed at the base, usually gradually long-taper pointed 

 at apex, margins generally entire, rarely a few teeth toward the apex, 

 green on both surfaces, generally mature leaves are smooth above and 

 below, more rarely somewhat rough above, and with some pubescence 

 along the veins beneath; fruit in late summer an orange red color, 

 gradually becoming darker until late autumn when it becomes red; 

 pedicels shorter or longer than the petioles, usually slightly longer and 

 ascending, fruit nearly globose, a trifle smaller than the preceding, and 

 about two-thirds as large as the first. 



Distribution. Virginia, southern Indiana, Missouri, eastern Kan- 

 sas, south to the Gulf States and west to Texas. In Indiana it is con- 

 fined to the southwestern counties. It is now known to definitely occur 

 in Sullivan, Gibson, Posey, Warrick and Spencer Counties. Two trees 

 were noted also, in the Muscatatuck bottoms near Delany Creek in 

 Washington County. A "single bush about eight feet high" was re- 

 ported from Jefferson County by Young. This may have been the 

 preceding species. It was also reported by Haymond from Franklin 

 County. 



Remarks. With one exception all the specimens of this species have 

 been found m very low ground. Usually it is associated with such low 

 ground species as pecan, sweet gum, swell-butt ash, and the cane. 

 One very peculiar specimen was found on the crest of a ridge about 

 seven miles north of Salem in Washington County. It was a tree about 

 fifteen feet tall, and had very narrow entire leaves. 



MORACEAE. THE MULBERRY FAMILY. 



Trees or shrubs with a milky sap; leaves simple, alternate, petioled, 

 3-5 nerved at the base; fruit fleshy. 



Branches without spines; leaves serrate; pistillate flowers in 



spikes 1 Morus. 



Branches with spines; leaves entire; pistillate flowers in heads. 2 Maclura.
