right the herries are blackish and ovate ; but 

 my specimens have no fruit. It has evidently 

 been often mistaken for the next, which has 

 shorter thicker leaves more acuminate, more 

 cordate and more obliqual, quite pubescent be- 

 neath ; it is nearer to C. micranthes of Antil- 

 les differing chiefly by larger serratures, pubes- 

 cent branches, petiols <Jc. 



549. CELTIS CRASSIFOLIA Lamark and many 

 Authors, C. cordata Persoon and others tree, 

 branches terete rough, leaves broadly ovate 

 acuminate, unequaly serrate, base cordate obli- 

 qual, thick or subcoriaceous, rough on both 

 sides, peduncles mostly biflore a small tree 15 

 to 40 feet high, with large dark thick leaves 

 quite rough, common from West Pennsylvania 

 to Missouri and Kentucky, blossoms in May. 

 Berries black large sweet, called Hackberries 

 or by corruption Hagberries, Hogberries. 



560. CELTIS RETICULATA Torrey, Eaton. 

 Leaves broad cordate pubescent subcoriaceous, 

 subentire, subobtuse, base unequal obliqual, pa- 

 pillose scabrose above, reticulate prominent 

 nerves beneath, peduncles uniflore in the 

 Western parts of Missouri and Arkanzas ex- 

 tending probably to the Origon Mts. found by 

 James described by Torrey ; I have not seen 

 it and only copy his account to show that it 

 differs no more from C. crassifolia than my 

 C. morifolia, all 3 have cordate leaves and re- 

 ticulate nerves, whence the name is not very 

 proper. Is it a tree or a shrub ? compare C. 

 patula.
