nearly equal divisions, upper lip of corolla entire or 2-cleft and lower 
3-cleft, 2 fertile included posterior stamens (the anterior mere sterile fila- 
ments or wanting), Style dilated or 2-lipped at apex, and a 4-valved pod. 
* Anthers with a broad connective, the cells transverse: stems mostly diffusely branched or 
creeping at base, soft viscid-pubescent or smooth: corollas 8 to 12 mm. long : bractlets 
foliaceous, equaling the calyx. 
+ Sterile filaments minute or none. 
++ Pedicels filiform, equaling or exceeding the leaves. 
1. G. pusilla Torr. Minutely viscid, almost glabrous, slender, 5 to 7.5 em, high: 
leaves oblong-linear, obtuse, entire, 3 to 8mm. long: corolla golden yellow, 8 mm. 
long, the lobes retuse or emarginate: pod 4 mm. long, ovate-conical, acute, much 
exceeding the reflexed or spreading calyx.—Arkansas and adjacent Texas. 
2. G. gracilis Benth. Glabrous or nearly so, small and slender, erect: leaves from 
oblong to linear-lanceolate, entire or sparingly dentate: corolla yellowish or whitish 
(commonly with a tinge of purple), 6 mm. long: pod globular but acutish, equaled 
by the calyx.—Eastern Texas. 
3. G. Virginiana L. Stem clammy-puberulent above, 10 to 15 cm. high: leaves 
lanceolate with narrow base, acute, entire or sparingly toothed: corolla 8 to 10 mm. 
long, with yellowish tube and nearly white lobes.—Throughout the Atlantic and 
Gulf region and across the continent. 
++ ++ Pedicels short, mostly shorter than the calyx. 
4. G. spheerocarpa Ell. Smooth, rather stout, 12.5 to 25 em. high: leaves lance- 
ovate to oblong or oval-obovate, 2.5 to 5 cm. long, toothed: corolla white: pod glo- 
bose, large (4 mm. in diameter) and pointless.—Extending from the Atlantic region 
into Texas. 
+ + Sterile filaments slender, tipped with a little head. 
5. G. Drummondii Benth. Puberulent and somewhat viscid: leaves lanceolate, 
acute, sparsely and acutely serrate, 12 to 20 mm. long, about equaling the pedicels: 
sepals and bractlets linear-subulate, much longer than the pod: corolla white or pur- 
plish-tinged, 10 to 12 mm. long: sterile filaments short.—Extending from the Gulf 
States into Texas. 
** Anthers with no broad connective, the cells vertical: sterile filaments tipped with a 
head: hairy plants, with erect rigid and more simple stems. 
6. G. pilosa Michx. Leaves ovate or oblong, sparingly toothed, sessile, 12 mm. 
long: flowers nearly sessile: corolla white, 6 to 8 mm. long, scarcely exceeding the 
calyx.—Extending into Texas from the Atlantic and Gulf States. 
12. ILYSANTHES Raf. 
Small and smooth annuals, with opposite leaves, small axillary pur- 
plish flowers on filiform naked pedicels or the upper racemed, 5-parted 
nearly equal calyx, short upper lip of corolla erect and 2-lobed, the 
lower larger and spreading and 3-cleft, 2 included posterior fertile 
stamens (anterior pair sterile, inserted in the throat, 2-lobed, one of the 
lobes glandular, the other smooth, usually short and tooth-like), 2-lobed 
stigma and an ovate or oblong pod. 
1. I. riparia Raf. (FALSE PIMPERNEL.) Much branched, diffusely spreading, 10 
to 20 cm. high, or at first simple and erect, leafy: leaves ovate, rounded, or oblong, 
sparingly toothed or entire, the upper partly clasping: corolla 6mm. long. (J. gra- 
tioloides Benth)—Extending into Texas from the Atlantic region.
