The reference ‘‘Plum”, in the last four, is to Plumier’s “Description 
des Plantes de 1 ’Amerique, ” published at Paris in 1693. An exami- 
nation of this work showed that neither this nor the later edition (1713) 
contained descriptions or figures of any Onagras, but Plumier’s Cata- 
logue (1703) lists these forms. The explanation doubtless is that these 
four polynomials had been furnished to Tournefort by Plumier, but the 
latter had failed to complete his plates for publication in either edition 
of the work referred to. Later, in Plumier’s Plantarum Americanar-um 
the figures are published in the 7th fascicle, 1758. There (6) is referred 
to Mentzelia while (7) is described as Jussiaea; (8) and (9) are 
described with polynomials as Oenothera, with a reference to Browne’s 
History of Jamaica (1756). The latter merely gives the polynomials 
of three “Oenothera” species, but Jacquin lists them in Select. Stirp. 
♦ Amer. Hist. (1788) and his plate, (Vol. 2, pi. 70) together with the 
description makes it certain that these are also species of Jussiaea, as 
might have been expected. 
Number (5), with small flowers, is evidently a species of Tournefort. 
It w^as afterward referred by Linnaeus to Oenothera frnticosa, (Sp. PI. 
p. 346). The plant which Linnaeus meant to indicate by this designa- 
tion was, however, not what we now know as 0. frnticosa, L., which 
belongs in a different group, but 0. muricata, L. as now known. This 
is shown by Barrelier (1714), who cites Tournefort ’s Onagra angusti- 
folia, caule ruhro, flore minore as a synonym for his Lysimachial 
angustifolia, spicata, lutea, Lusitanica, with a figure (990). This figure 
is reproduced in plate 3 of this paper, and in comparison with the figure
