closely resembles that of the plant called Polygala paiicifolia 

 Willd. The genus is, as far as I can find, to be considered as, 

 monotypic.

Other members of the Linnaean genus Polygala that msty 

 well be removed therefrom arc the following: 



AnThalogea Rafmesque, New. Fl. Am. IV., p. 88, (1836). 



The plant is biennial and beside the characters referred to 

 by Rafinesque, produces regularly subterranean and often aerial 

 cleistogamous flowers. Together with Polygala paiicifolia Linn, 

 it is the only other plant of the aggregate having apetalous or 

 cleistogamous flowers.

Trichlisperma Raf. 

 The beautiful little plant with flowers most showy of all 

 the group of Polygala has a number of notable distinctive characters 

 that deserve consideration for generic standing. The plant was 

 made by Rafinesque type of his genus Trichlispernia.' The crested 

 elongated corolla recalls that of Galypola. The plant is perennial 

 and produces cleistogamous flowers which were not unnoticed 

 by Rafinesque though not so called by hiin, nor was he perhaps 

 aware of their exact nature.^ The habit too of the plant is quite 

 diff"erent from any other Polygala. The peduncled flowers are 

 different from those of either this or Galypola, the corolla resembling 

 the latter somewhat but the wings those of Polygala. Stamens 

 only six in two sets of three. Rafinesque mentions also differences 

 in the seed. Rafinesque says that the roots contain oil of winter- 

 green.-'
