The basionym of Galactia volubilis is Hedysarum volubile L. 

 (1753:750). Again, Linnaeus had no specimen directly supporting this 

 name, but cited three references: Dillenius (1732), Linnaeus's own 

 Hortus Cliffortianus (1737), and Royen (1740). Only one of these 

 authors appears to have relied directly upon a specimen. Royen merely 

 referred to Hortus Cliffortianus, while Hortus Cliffortianus relegated 

 the plant to its Appendix, an indication that there was no underlying 

 specimen, then cited Dillenius. Fortunately the Dillenius specimen is 

 extant (photo, OXF); Duncan found it to be the large-flowered plant. 

 Thus Linnaeus, by inclusion of the Dillenius reference and, indirectly, 

 Dillenius 's specimen in his circumscription, caused Galactia volubilis 

 (L.) Britt. to be based on the large-flowered plant. 



The exceptionally larger leaflets and flowers of plants of Galactia 

 volubilis from populations in west-central peninsular Florida, brought 

 to the attention of the present authors by Leland and Lucy Baltzell, 

 Lakeland, has suggested the need for formal recognition. 



Galactia volubilis (L.) Britt. var. baltzelliana D. B. Ward & D. W. 

 Hall, var. nov. 



Similis G volubilis s.s. (sensu Duncan, 1979), sed floribus 

 grandioribus (a 21 mm. longis), foliis subcoriaceis, et caulibus quibus 

 fortiter scandentibus.
