+-(. ++ ++ Pube nunc stellulata, nunc simplici rigidula, nunc vix ulla : 

 folia (rarissime subcordatu) saepissime in petiolum angustata : stylus

 &, fusco-maculata (Rouville) Dun. in DC. — Shore of Virginia? and 

 N. Carolina to Florida. The species was no doubt founded on the 

 Buenos- Ayrean plant, and it is not clear that Linnteus ever had it from 

 '• Virginia." The plant of our coast, if I mistake not, was what Lin- 

 nseus, in appendix to the second edition of Species Plantarum, named 

 P. Pennsylvanica, although he does not pretend to have it from Penn- 

 sylvania, and it is not found there. His herb, specimen is " Hort. Ups." 

 'I find nothing to distinguish the broader-leaved North American plant 

 from the South American ; and the range is not very uncommon for a 

 sub-maritime species. The name alludes to the viscous berry : the 

 herbage is not viscid. In the Manual I inadvertently applied the name 

 of P. viscosa to a viscid-leaved species, P. heterophylla of Nees.
