4. M. Pavia (Linn.): stamens somewhat shorter, or a part of them a 

 little longer, than the (red) corolla; petals 4, connivent, very unequal; the 

 claws of the lateral ones about the length of the tubular calyx ; thyrsus loose, 

 the branches few-flowered ; leaflets 5, oblong-lanceolate, cuneate-oblong, or 

 oval, slightly acuminate, unequally serrulate, minutely pubescent, or nearly 

 glabrous except along the veins beneath. — Ait. Kew. 1. p. 494; Walt. Cur.

In fertile valleys ; mountains of Virginia ! to Georgia ! Louisiana ! and Ar- 

 kansas ! April-May. — A shrub 3-10 feet high ; near the mountains some- 

 times a small tree. Leaflets often somewhat doubly serrate, all except the 

 lateral ones usually attenuate at the base, at length petiolulate, smooth and a 

 little shining above. Branches of the thyrsus about 3-flowered : pedicels 

 slender. Flowers large. Calyx purplish', nearly glabrous, tubular-funnel- 

 shaped. Upper petals longest ;' the claw about thrice the length of the small 

 spatulate limb: hmb of the lateral petals roundish, about the length of the 

 claw, somewhat convolute. Stamens 6-8 : filaments filiform, nearly straight, 

 hairy beloAv, as also the claws of the petals, sometimes all a little shorter than 

 the lateral petals ; but a portion usually a little exceeding the upper petals.-— 

 Our p. discolor, of which we have specimens both from Georgia and Louisi- 

 ana is not improbably the M. discolor of Pursh. The inflorescence resem- 

 bles that of JE,. flava; but the flowers (apparently pale dull red, or purple) 

 are wholly those of M. Pavia.— According to Elliott, the bruised branches 

 or powdered seeds of this species are sometimes employed to stupify fish : 

 when the water of small ponds is impregnated, the fish rise to the surface al- 

 most lifeless, and may be taken with the hand. The root, according to the 

 same authority, is used as a substitute for soap in washing woollen clothes.—

5. Ml. flava (Ait.): stamens shorter than the (light yelloAv) corolla; pe- 

 tals' 4 connivent, very unequal ; the claws of the lateral ones exceeding the 

 campanulate calyx ; branches of the thyrsus 4-7-flowered ; the flowers most- 

 ly unilateral; leaflets 5-7. elliptical or cbovate-oblong, acuminate, serrulate, 

 more or less canescently pubescent beneath.— ^i^. Kew. 1. p. 494 ; H Hid.

' Near large rivers (in rich soil), Western States! and along the AUeghany 

 Mountains^from Virginia and N. Carolina ! to Georgia. April-May.— Tree 

 30-80 feet high (in the Southern States sometimes only 4-6 feet high, ac- 

 cording to Elliott) ; the trunk often 3 or 4 feet in diameter. Petioles with a 

 pubesc'ent Une along the upper side. Leaflets glabrous above, except the 

 midrib and veins, Avhich are often clothed with a reddish-brown pubescence, 

 at first nearly sessile, at length petiolulate ; the lateral ones sometimes rather 

 obtuse, but the others attenuate, at the base. Peduncles, pedicels, and calyx 

 pubescent. Pedicels very short. Flowers as large as in M. Pavia. Petals 

 puberulent ; the claAvs villous within : upper ones a little exceeding the 

 others- the spatulate limb minute: lateral ones large, roundish, subcordate at 

 the base. Stamens usually 7 : filaments straight or somewhat arcuate, sub- 

 ulate villous. Ovary pubescent. Fruit 2 inches or more in diameter, about
