Morisia hypogsea is a singular little monotypic Crucifer, 

 the position of which in the family is rather obscure. I 

 placed it in the Tribe CaJcilmese in the " Genera Plantarum," 

 which brings it near to Erucaria, a genus in which it was 

 placed by Viviani, and by Moris, the latter of which 

 authors accepted subsequently J. Gay's constituting of it 

 a distinct genus, bearing the name of the excellent author 

 of the " Flora Sardoa." It differs in the singular habit 

 of decurving the scape after flowering, and burying the 

 ripening fruit in the soil, recalling the two other crucifcrs 

 Cardamine chenopodifolia, Pers., of Brasil, and Geococcus
