Umbels solitary, one between each pair 

 ot leaves, frequently 2, sometimes 4—6 flowered, longer than the 

 leaves. Petals obovate, very slightly emarginate, S times as long as 

 the calyx. Stamens united to the middle of the filaments. Styles 

 varying a little in length, but geaerally about as long as the interior 

 Stamens. Stigvias thickened, 3 cleft or forked. Capsule 5 an-led, 

 ^ celled, mucronate, thickly clotlied with horizontal hairs. Seeds 

 inanv, ovate, attached to the central receptacle. 



1 have sometimes supposed that this may have been the original 

 0. Dillenii, a species which I believe It will be difficult to identify. 

 None of our species of Oxalis, that I have seen are strictly and uni- 

 formly biflorouS) no one has petals conspicuously emarginate. We 

 possess probably many species not yet described, for no genus is more 

 extensively diftused over our country than the Oxalis, nor can be 

 found in a greater variety of soils. Two species I have determined
