 States. Type species : Anychiastritm ripdrium 

 (Chapm.) Small.

 pressed; styles 2, distinct, or united at the base; ovule solitary, amphitropous. Utricle sub- 

 globose, somewhat compressed, longer than the calyx. [Derivation same as Paronychia.] 



Only the following species, natives of eastern North America. Type species : Anychia dicho- 

 toma Michx. 



Pubescent ; flowers sessile ; stems mostly prostrate or ascending. 

 Glabrous or nearly so ; flowers pedicelled ; stems usually erect.

2. A. canadensis. 



I. Anychia polygonoides Raf. Forked Chick- 

 weed. Fig. 1723 



Anychia polygonoides Raf. Atl. Journ. i6. 1832. 

 Anychia divaricafa Raf. New Fl. N. A. 4 ; 42. 1836. 



Pubescent, stems mostly prostrate or ascending, 

 much forked, 3-10' high, the internodes often 

 shorter than the leaves. Leaves narrowly elliptic,

 sessile in the forks, more or less clustered, scarcely 

 J" high, inconspicuous except when fully expanded ; 

 stamens commonly 2 or 3, sometimes 5. 



In dry woods, thickets and in open places, Maine to 

 Minnesota, south to Florida, Alabama and Texas. As- 

 cends to 5200 ft. in Georgia. Illustrated in our first 

 edition as A. dichotoma Michx., but this proves to he 

 the same as the following species. June-Sept.
