of the Genus ToficMid. 239 



NartJiecium, which agrees most in habit with the genus before 

 us, is distinguished from it by the want of a cal3'x ; as well as by 

 having a simple gcrmen and single style; hairy filaments; and a 

 membranous tunic, tapering at each end, to the seeds. Anthe- 

 ricum, including the Plialanginm of Tournefort and Jnssieu, dif- 

 fers from Tojieldia in having no calyx ; a simple germcn and 

 style ; and angular seeds. Helonias, to which Willdenow refers 

 our T. palustria, confounding under that solitary species nearly 

 the whole genus, has a simple germen and capsule, though three 

 styles; very few seeds in each cell ; and wants the calyx. 



The species of Tojieldia have hitherto been even less understood 

 than its generic characters, as the following exposition will show.

 Native of the black boggy margins of pools and trickling rills, 

 on the mountains of Lapland, Scotland, Durham, and North 

 America, particularly lake Mistassins, flowering from June to 

 August. 



This is a perennial herbaceous plant, of humble stature, entirely 

 smooth in every part. The root is horizontal and somewhat tu- 

 berous, or woody, but slender, with very long, tough, white, zig- 

 zag
