NOTES ON NEW AND OLD GENERA 191

 genera Pentstemon and Viticella elsewhere noted. '^ 



Phenianthus Raf. 



The plant called by Linnaeus Lonicera sempervirens by its 

 almost regular corolla of four small subequal lobes and very long 

 tube would seem to be at least as much entitled to generic standing 

 as Nintooa Sweet. The latter has not nearly as characteristically 

 different floral characters as the other. The flowers of Rafinesqne's 

 segregate plant Phenianthus for L. sempervirens are even more 

 strikingly different from typical Lonicera than are those of the 

 recognized genus Xyiosteunt Adams. The genus was proposed by 

 Rafinesque and is probably a good one.

Triodanis Raf. 



The American plants hitherto referred to Specularia (Heist.) 

 Fabr. or Legouzia Durand are in fact rather different from the 

 common members of the old world genus with which they have 

 almost invariably been associated. Rafinesque well acquainted 

 with both the European Specularia Speculum, Veneris (or Specu- 

 laria Speculum wrongly called) and also knowing well our American 

 plants was quick to recognize the differences between the two. 

 He therefore made our plant Specularia perjoliata (Linn.) DC. 

 the type of a new genus Triodanis. 



The calyx according to his diagnosis is notably irregular 

 in Triodanis. Three of the sepal lobes are narrower than the 

 others and turned away from them giving the whole a bilabiate 

 appearance. The corolla is deeply and the flowers are axillary 

 on stems or the few branches, whereas in the European plant
