in general, that Vahl, in his herbarium, as we are assured by 

 De Candolle, marked it as a Cleome. Of this, the Macropo- 

 dium nivale of Brown, I am not aware that any figure exists, 

 except the one published in Pallas' Travels, a work probably 

 in the hands of few Botanists, and where it is not to be ex- 

 pected that the analysis of the fructification is exhibited with 

 the precision that will be satisfactory to those who adopt the 

 new arrangement of the still difficult and most extensive 

 family of plants to which this genus belongs. On this ac- 

 count, and because I possess no perfect fruit of the new 

 species, I shall render my account of this genus more com- 

 plete by representing that of M. nivale. 

 Gen. Char. Cal. erectus, basi latiore. Fetala calyce 

 multo longiora, linearia vel lineari-spathulata. Stamina 

 libera. Antherce lineares, vel oblongse. Stylus subnullus. 

 Stigma parvum, capitatum. Siliqua stipitata, lineari-ensi- 

 formis, compresso-plana, pedicellata: valvis planis, ob- 

 scure reticulatis, medio uninerviis. Semina suborbicularia; 

 compressa, vmiseralia, vix, nisi in statu juniore, marginata., 

 Cotyledoties accumbentes. — Radix annuus vel perennis. 

 Caul is herbaceus, simplex vel ramosus. Folia integra vella-
