Leaves downy,ternate, stalked leaflets ; oval, rather rhomboidal, coarsely and unequallycut, rugose, tapering to the base. Flowers very small, reddish,appearing upon the naked branches before the leaves. According toGuibourt this should be the plant that yields the African Bdellium," only the tears of Bdellium collected on the bush by M. Perrottet arehardly bigger than peas; therefore the Bdellium of commerce is eitherproduced by a different species, or the Niouttout must become a largertree than M. Perrottet saw." (ii. 498.) It must be remarked thatnothing is said about Bdellium in the Flora Senegambia; of Perrottetand Guillemin.STAGMARIA.Calyx inferior, tubular, deciduous, irregularly ruptured atthe edge.
