differed, as I shall show, in certain respects, from the 0. grandiflora of 
Alabama which is now in cultivation. But the broader and relatively 
shorter leaves and the other characters mentioned seem to refer to this 
form, although all the distinguishing characters which would lead to 
certainty are unmentioned. The flowers of the reputed Virginian 0. 
grandiflora may be somewhat larger than in 0. Lamar cMana. Moreover, 
exceptionally tall and robust plants frequently have correspondingly 
larger flowers. I shall refer to this again later. It is the earliest de- 
scription I have seen which could refer to 0. grandiflora.^ 
Tournefort, in his Institutiones (1700), recognized large- and small- 
flowered forms, and in 1714 Barrelier gives very instructive figures of 
three species as follows : 
(1) PI. 989. Lysimacliia latifolia, spicata, lutea^ Liisitanica, with the syn- 
onym Onagra angustifolia Tourn. Inst. 302. 
(2) PI. 990. Lysimacliia angustifolia, spicata, lutea, Lusitanica, with the 
synonym Onagra angustifolia. caule ruhro, flore minore. 
Tourn. Inst. 
(3) PI. 1232. Lysimacliia lutea, corniculata, latifolia, Lusitanica, with the 
synonym Onagra latifolia, floriMis amplis Tourn. Inst. 
The first tw^o species are small-flowered forms, and it is very probable 
that they represent races of what are now known as 0. hiennis L. and 
0. muricata L. In plate 989 the spike is very dense, while in plate 990 
the petals are deeply emarginate, smaller and the rosette leaves narrower 
than in 989. The rosette leaves have long petioles in both. The third 
species has much larger floivers, the leaves are represented as markedly 
repand-denticulate, sometimes more or less curled. Though there is 
little basis for judgment, the leaves seem to suggest 0. Lamar chiana 
rather than 0. grandiflora. These figures are reproduced in plates 3 
and 4. 
The Ilortns Cliff or tianns, published at Amsterdam in 1737, gives (p. 
144) two species of Oenothera, with synonomy as follows, the genus 
Oenothera having been previously characterized by Linnaeus in the 
Genera Flantarum : 
1. Oenothera foliis ovato — lanceolatis clenticulatis, fiorihus lateralihus in 
summo eaulis. 
Onagra latifolia Tournef. Inst. 302. 
Lysimacliia lutea corniculata Bauh. pin. 245, 516. 
Lysimacliia lutea corniculata non papposa virginiana major. Moris. Hist. 
2 p. 271. 
^Since writing’ this I have noticed that L’ Heritier, in his description of O. grancU- 
ffora (see L’ Heritier MS) says “Conf. Onagra latifolia floribus amplis. Tourn. inst. 
302,” which clearly confirms my conclusion.
