Herbs, annual (ours), erect or diffuse. Leaves opposite, entire or dentate. Flowers 
white or yellow, peduncled, solitary in the leaf-axils. Calyx 5-lobed; lobes narrow, slight- 
ly unequal. Corolla-tube cylindric; limb more or less 2-lipped; upper lip entire to 2-cleft; 
lower lip 3-lobed. Anther-bearing stamens 2; anther-sacs transverse, 2 other stamens mere 
antherless rudiments. Stigma slightly 2-lobed. Capsule loculidical and septicidal, ovoid 
or globose, 4-valved. Seeds longitudinally and transversely striate. (L. gratia—a favor, 
from supposed medicinal value.) 
A. Peduncles 2-bracted under the calyx; sepals 6 mm. long, shorter than the corolla; 
capsule ovate, about equaling the calyx. W. C. E. 
G. virginana L. 
AA.  Peduncles bractless; sepals 8—12 mm. long, equaling the corolla; capsule glo- 
bose, much shorter than the calyx. W. C.

ILYSANTHES FALSE PIMPERNEL 
Herbs, annual or biennial, glabrous, slender, branching; ours 7.5—-20 cm. high, in 
mud. Leaves opposite, mostly dentate, mostly sessile; in ours 3—-7-veined from base, 
12—25 mm. long. Flowers small, purplish or reddish, peduncled, solitary in the leaf- 
axils; peduncles not bracteolate. Calyx 5-lobed; lobes linear. Corolla irregular; tube 
somewhat expanded above; limb 2-lipped; upper lip 2-cleft, erect; lower lip larger, 
3-lobed, spreading. Stamens 2, included; antherless filaments 2, 2-lobed, one lobe capitate 
and glandular, other lobe shorter and glabrous. Stigma slightly 2-lobed. Capsule ovoid 
or oblong, septicidal. Seeds wrinkled. (Gk. ilys—mud, anthos—flower; from the hab-

I, dubia Barnh. 
LIMOSELLA MUDWORT 
Herb, annual or perennial, low, glabrous, succulent, floating or creeping on mud,

linear, or with slender petioles and oblong or linear-oblong blade. Flowers small, white or 
pink or purple; peduncles scape-like, I-flowered, filiform. Calyx campanulate, 5-lobed. 
Corolla nearly regular, open-campanulate; tube short; limb 5-cleft. Stamens 4, hardly 
exserted. Ovary 2-celled at base, I-celled above; stigma capitate. Capsule globose or 
oblong, becoming |-celled. (L. limus—mud, sella—a seat; because it is a stemless mud 
plant.) W.E. (L. tenuifolia.) L. aquatica L. 
DIGEITALEAE (Fox-clove “| RIBE)—<Herbs.. annual or perennial, erect to 
creeping or almost acaulescent. Leaves opposite or alternate, scattered or nearly all basal, 
pinnately-veined or several-veined from the base, entire to divided, 0.4—25 cm. long 
(ours). Flowers solitary in the leaf-axils, or in terminal or axillary racemes or spikes. 
Calyx 4—5-toothed or -lobed. Corolla rotate or campanulate or salver-shaped or tubular, 
not swollen at base, often nearly regular, variously colored but not green nor yellow. 
Anther-bearing stamens 2 or 4; antherless ones 0. Capsule dehiscent. Seeds few to 
many. 
A. Leaves 0.4—10 cm. long, often several-veined from the base, alternate or oppo- 
site; plant prostrate or erect or almost acaulescent, usually less than 3 dm. high; co-
