Spach, in Vol. XI of his "Histoire Naturelle des Veg. ; 1842, gave a natural ar- rangement of the oaks, which is founded on the form and duration of the leaves, the cup, and the ripening. Endlicher maintained the same disposition and characters, only changing the name of one of the sub-genera, and establishing for it three sub- divisions of the sub-genus Lepidobalanus, which includes nearlj' all our American species. De Candolle adopts the three sub-genera of Endlicher, adding two more, viz: the sub-geuus Androgyne, formed by the single Californian species, Q. densiflora, Hook, which has tl>e flowers of both sexes in an upright spike, male above, female be^w, the abortive ovules at i\\c apex of the seed; the other new sub-genera i» Pasana, with south Asiatic species. All the other American species belong to the sub-genus Leindobalaniis. The arrangement in the "Pro- dromus" is thus: I.—Lepidobalanus. 2 1.
