AMPHIANTHUS. 
Calyx 5-parted, and unequal. Corolla tubular-infundibuliform ; 
limb somewhat bilabiate, 4-lobed ; inferior lobe somewhat larger. 
Stamens 2, superior, included; inferior ones wanting. Style 
simple ; stigma minutely bifid. Capsule obcordate, compressed, 
2-valved, opening at the summit; valves entire. Seeds nume- 
rous, naked, anatropous. Herbaceous, minute, annual, throwing 
up filiform scapes; radical leaves linear, sessile ; flowers solitary, 
both radical, and at the summit of the scapes.— Nat. Ord. Scro-

AMPHIANTHUS PUSILLUS. 
Root annual ; fibrous, the fibres compressed, linear. Stem very 
short, compressed, bearing a tuft of oblong linear leaves at its 
summit. Leaves about 2 lines long, rather obtuse, entire, vein- 
less, somewhat succulent. Scapes filiform and very slender, and 
1 to 14 inches in length, compressed, bearing a single pair of op- 
posite oval bracts at the top. Bracts nearly sessile, obtuse, some- 
what succulent, obscurely 3-nerved. Flowers very minute ; rad- 
ical ones 2 to 3 on each plant, attached to short recurved pedun- 
cles, which originate from the tuft of leaves; terminal ones soli- 
tary, nearly sessile between the bractez, (that is, without any 
proper pedicel.) Calyx 5-parted; the division oblong, erect, 
very obtuse, dotted with a number of minute glands. Corolla 
scarcely a line in length, white, straight, tapering downward ; 
limb somewhat dilated, slightly bilabiate, 4-lobed; the lobes 
erect, rounded, and somewhat emarginate ; the inferior one larger. 
Stamens constantly 2, superior, scarcely half as long as the co- 
rolla; filaments slender, adnate the lower two thirds of their 
length, smooth; cells of the anthers approximated, subglobose. 
Ovary ovate, acute, compressed, surrounded at the base witha 
minute red disk, 2-celled, many-seeded; style rather larger than 
the ovary, subulate; stigma minute, bifid at the summit. Cap- 
sule broadly obcordate, compressed, opening along the edge at 
the summit; valves entire, convex; dissepiment adhering to the 
valves. Seeds 10 to 15 in each cell, linear oblong, fuscous, 
straight; embryo straight; cotyledons oblong, distinct; radicle 
oblong.
