Achenia oblong, silky villous, angled base ; pappus copious, unequal, 

 scabrous or plumose hirsute. 



Corolla infundibuliform, on a slender tube ; teeth glabrous, about 

 one-fourth of the length of the tube ; anthers equal or exsert by their 

 ^vhite villous appendages. Style included, brownish purple ; append- 

 ages shorter than the stigmatic portion, oblong-ovoid. 



A new genus is proposed, founded upon a remarkably orvamental 

 shrub, belonging to the natural order, Scrophularinoi. 



Saccularia, (Kellogg). — Calyx five-parted, ovate-oblong, acute, 

 quincuncial estivation. Corolla tubular, bilabiate ; tube elongated, 

 sub-cylindrical, saccate below at the base; upper lip erect; lower lip 

 spreading. Stamens four, fertile, didynamous, without any rudiment 

 of a fifth ; throat mostly naked ; style filiform. Stigma undivided as in 

 Pentstemon, simple or lobed. Capsule globose, slightly depressed, and 

 compressed, ventricose somewhat obliquely; each cell opening by an 

 irregular eight-toothed orifice, near the apex. Seeds numerous, 

 oblong truncate, small ; testa ribbed lengthwise, deeply chinked ; 

 surface of the elevations irregular or toothed, dark brown. Seeds 

 attached to a roundish rugose-pitted placenta, which is involved, and 

 fixed by the complete and permanent dissepiment. 



S. Veatchii, (Kellogg). — Stem suffruticose, with myriads of slen- 

 der, twiggy rods, of nearly uniform size, very straight, bright green 

 or glaucous, glandularly villous and somewhat canescent above ; 

 branches ternate and opposite ; erect, terminal twigs ; frequently con- 

 stricted at the bifurcation. 



Leaves verticillate by threes or opposite, lanceolate, mucronulate, 

 acute ; a mucronate gland at the apex ; short petioled, or subsessile, 

 entire, hirsute above at the base, glandularly villous on the lamina 

 above, densely glandularly hirsute below; small, (one-sixteenth to 

 half an inch long) very remote. 



Mowers in elongated terminal racemose panicles, (six inches to a 

 foot in length) whorled in threes; a bract (or leaf) at the base of 

 each pedicel ; pedicels filiform, erect, ascending, bent above, one-flow- 

 ered; lower pedicels longer than the flower; upper about half as long. 



Tubular flowers about one to one and a quarter inches in length, 

 minutely glandular villous externally ; upper lip erect, notched, 

 reflexed at the sides, glandular villous within ; lower lip recurve- 

 spreading somewhat trifid, lateral portions shorter or sub -equal, mid- 

 dle lobe rounded, obtuse, folded under, bearded above with glandular 

 hairs ; a broad line of short stipitate or papillose glands, extends back 

 from the middle lobe to the base of the tube ; throat otherwise naked. 



Style filiform, glabrous, persistent ; stigma simple, acute (minutely
