406 M. A. Curtis on Neio and Rare Plants. 



Art. XXXVIL — New and Rare Plants, chiefly of the Carolina*; 



by M. A. Curtis. 



Malva triangulata, Leavenworth. — M. Houghtonii, Ton. fy 

 Gray ! This species was detected some years since on the Ca- 

 tawba in Lincoln Co., N. Car., and sent to me by Dr. C. L. Hunter. 



Ptelea mollis, n. sp. — P. trifoliata, /?. mollis, Torr. fy Gray? 

 I. 680. Lateral leaflets oval, the terminal obovate, with an ab- 

 rupt acute point, the underside with the petioles, panicles and 

 young branches, clothed with a soft whitish silky villus ; cymes 

 compact, with short branches ; style long ; filaments equalling the 

 anthers. — Wilmington, N. Car. Also, Newbern, N. C; George 

 Wilson, Esq.: the low country of S. Car.; Rev. T. J. Young. 



The style in this species is twice as long as in P. trifoliata, 

 while the filaments are only about one third or one fourth as long. 

 The mature leaves are much more rigid. With the exception of 

 the style, this plant is much smaller in all its parts, and the sepals 

 very deciduous. Flowers tetrandrous. 



Galactia sessiliflora, Torr. fy Gray /—This species extends 

 along the interior portion of the sandy region of S. Car., to Cum- 

 berland Co. in N. Carolina. 



Petalostemon corymbosum, Michx. var. (?. — Folioles 5-7 pairs 

 narrowly oblong linear, commonly emarginate. A very marked 

 variety. Low country of S. Car. ; 



Rev. T. J. Yoan 



Baptisia Serenae, n. sp. — Very smooth, branching ; leaves ob- 

 long-obovate, cuneate, petioled; flowers (yellow) in a long loose 

 central raceme and in short racemes terminating the branches ; 

 pedicels longer than the calyx in fruit ; segments of the calyx 

 villous on the inside ; legume oblong inflated, the stipe longer 

 than the calyx. Society Hill, S. Car. Flowers May, June. 



Diffusely branched, 1-2 feet high, partaking somewhat of the 

 habit of both B. alba and B. tinctoria, its period of flowering be- 

 ing between theirs. It differs from the latter in the characters 

 given above and in not turning black in drying : — from B. Lecon- 

 tei in its smoothness, the absence of persistent bracts, the shape 

 of the legume, &c. Folioles about an inch long,— legume, 

 without the stipe, about 8 lines. 



Alchemilla akvknsis, Scop. — Common on grass-plats along 

 the Pamlico in Beaufort Co., and around Oxford, N. Car. Evi- 

 dently introduced.
