The florida has most of the gum mucilageand extracts ; the sericea the next, which appears to be an intermediate between the florida and cinchona ;while the latter possesses most of the resin. Their virtues appear similar, and equal, in their extract and resin possess all their active powers. The extract appears to possess all their tonic pow-ers. The resin, when perfectly separated from the extract, appears to be purely stimulant; and probablythe tonic powers of the extract, are increased when combined with a portion of the resin, as in the spirit-uous Genus PINCKNEYA, Mich. Kubiacese. Syst. Nat. , Pincneya, Cincliona, Mussanda, Pentandria Monogjnia. SijSl. Lin. Of Derivriiions. The name Pinckneya was so called by Michaux, in honour of Mr, Charles Pinckney, of South Carolina, agenllemari who was erigageJ in the cause and advancement of holaiiical science. The other names have been applied to the tree*cf this genus, from the resemblance they were supposed to bear to the Cmchona, and Mussaenda. Generic Characters. Sepals unequal, one or two of them foliaceous. Corolla a long tube. Filaments inthe base of the tube. Capsules 2-valved, valves bearing the divisions in the middle.—Loudon, Erie, ofPlants. HIS genus is nearly allied to Mussaenda, and embraces but one spe-^i ju- cies, a native of North America. To the same order belong a great^n^ number of genera; but a icw of the species of which are suffi-^ ciently hardy to withstand the climate o
