M. Fr.\seri, Decaisne in DC. Prodr. viii. 513, "Carolina? Frasrr," was probably West

 rowly lanceolate, cuspidate-acuminate, rounded at base, glandular at base of midrib : 

 peduncles shorter than the petiole and the 3 to 5 pedicels, often very short : corolla (nearly 

 2 lines long, greenish outside), 5-parted; the lobes linear and strongly white-villous inside : 

 scales of the crown slender-subulate, on the base of the corolla, a little surpassing the
