98 PENNELL: PLANTS OF THE SOUTHERN UNITED STATES 
1. COMMELINA COMMUNIS L. 
Commelina communis L. Sp. Pl. 40. 1753. ‘‘ Habitat in America.” 
Apparently an erroneous statement of nativity, as the Linnean — 
diagnosis, as well as the fuller description and figure of Dillenius 
(Hortus Elthamensis 93. pl. 78. 1732), appear to apply to this 
originally East Asian species. All specimens in the Linnean ~ 
herbarium, from photographs sent me, are evidently the species 
here described. 
Flowers and fruits August to October. 
Moist loam or sandy soil, eastern Massachusetts to Virginia 
and western North Carolina; also in Jackson County, Missouri, — 
and probably in the intervening area. Abundant as a weed — 
eastward. Evidently introduced from eastern Asia. :
