190 FABACEAE. 



Bradburya virginiana (L.) Kuntze, Spurred Butterfly Pea, North 

 American and West Indian, listed as Bermudian by Eein, has not been found 

 by subsequent collectors. It is an herbaceous vine with purplish pea-like 

 flowers and narrow linear flat pods. [Centrosema virginiana Benth.] 



Balsamocarpon brevifolium Clos., a Chilian shrub, grown from seed by 

 Lefroy in 1875, failed to survive. 



Lefroy records the existence of an indigenous species of Aeschynomene, 

 resembling a small Mimosa at Paynter's Vale, but a thorough search of that 

 locality at different times in the season has failed to reveal its presence there 

 at this time. 



Lefroy also records the introduction of a species of Argyrolohium in 1874, 

 which lived until 1877.
