The former has always been regarded as a synonym of P. Phila- 
delphica Lam. Lamarck cites Miller's figure 1, plate 206, but as 
stated before this is P. Vzrginiana. Undoubtedly he only looked 
at the figure without reading the description. Miller describes 
his plant as perennial and hairy, Lamarck his as annual and 
glabrous. As far as Miller's figure is concerned it might as well 
represent one as the other. One thing that has caused much 
confusion, is that P. Philadelphica is generally described as the 
only species in which the berry fills and even bursts the calyx, a 
character that is far from constant, and also found in ?. longifolia 
Nutt., and still more common in P. aeguata Jacq. The character 
is not given in the original descriptions of either P. Philadelphica 
Lam. or P. chenopodifolia Willd. It is given in the original de- 
scription of P. ovata Poir.,* which has been regarded as a syn- 
onym of P. Philadelphica Lam. To me it seems more likely to be 
a synonym of P. aequata. As far as this latter is concerned, it is 
rightly understood and the plant agrees perfectly with Jacquin's 
description and plate,f but unfortunately there is an older name 
P. 1socarpa Brot., described in Hornem. Hort. Hafn, and the 
species must take that name. 
N. J. Jacquin described P. Barbadensist in 1781. It is nearly 
related to P. pubescens and P. pruinosa, and has been regarded as 
a variety of the former species. It differs from it in its erect 
habit, its larger, more cordate and more toothed leaves, and its 
larger, more elongated fruiting calyx. It was based on Dillenius' 
figure of “ Solanum Barbadense nanum Alliariae folio,’ which is 
cited by Linnaeus as a synonym under P. pruinosa in the second 
edition of Species Plantarum. Elliott, therefore, adopted the 
name P. pruinosa for P. Barbadensis. The reference is, however, 
not found in the first edition of Species Plantarum, and according 
to Dunal, and others, Linnzus erred when he referred Dil- 
lenius’ plant to his species P. pruinosa. P. Barbadensis is well dis- 
tinct from P. pruinosa, but differs from P. obscura Michx. § in no 
other a. than in its hairiness. The two are but one aper
