S. MENTIENS (Pohl, Ic. Bras. p. 187, t. 193). Herbacea, erecta, caulibus 
deorsum glabris sursum pubescentibus, foliis petiolatis ovatis acutis 
serratis utrinque viridibus glabris, bracteis late ovatis acuminatis 
coloratis deciduis, racemis simplicibus modice densis, calycibus 
membranaceis coloratis accrescentibus tubuloso-campanulatis den- 
tibus subpatentibus deltoideis, corollis coccineis calyce quadruplo 
longioribus tubo ventricoso labiis brevibus, stylo glabro corolla 
subequante.—Benth. in D.C. Prodr. xii. 330. 
A native of the neighbourhood of Rio Janeiro. 
Stems herbaceous, a foot and a half to two feet high, sparingly 
branched, erect, the lower part glabrous, the upper finely 
pubescent. Lower petioles glabrous, an inch and a half to two 
inches long. Leaves herbaceous, green and glabrous on both 
sides, ovate, acute, finely toothed, the lower ones three to four 
inches long, the base rounded with a short haft. Raeeme half a 
foot long when fully developed, the upper part dense. Bracts 
broad-ovate, acute, brightly coloured, conspicuous in the early 
stage but soon deciduous. Pedicels downy, two to three lines 
long. Calyx finely pubescent, tubuloso-campanulate, bright- 
coloured, at first four to five lines long, with spreading deltoid 
teeth rather shorter than the tube, membranous and accrescent 
after the corolla falls. Corolla bright scarlet, sixteen to eighteen 
lines long, the tube stout, ventricose, subglabrous, three times as 
long as the calyx, the lips reaching scarcely a quarter of the way 
down. Style glabrous, like the stamens included in the corolla. 
Closely allied to the well-known S. splendens (Bot. Reg. t. 687) 
and the Mexican S. ivolucrata (Bot. Reg. t. 1205; Bot. Mag. 
t. 2872).
