Calyx 5-parted, and unequal. Corolla tubular-inftmdi- 

 buliform ; limb somewhat bilabiate, 4-lobed ; inferior lobe 

 somewhat larger. Stamens 2, superior, included ; inferior 

 ones wanting. Style simple ; stigma minutely bifid. Cap- 

 sule obcordate, compressed, 2-valved, opening at the sum- 

 mit; valves entire. Seeds numerous, naked, anatropous. — 

 Herbaceous, minute, annual, throwing up filiform scapes; ra- 

 dical leaves linear, sessile ; flowers solitary, both radical, and 

 at the summit of the scapes. — Nat. Orel. SenoPBULAitiNEJE. 



Amphianthus pusillus. 



Hoot 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, veinless, somewhat succulent. 

 Scapes filiform and very slender, and 1 — li inch in length, compressed, 

 bearing a single pair of opposite oval bracts at the top. Bracts nearly 

 sessile, obtuse, somewhat succulent, obscurely 3-ncrvcd. • Flowers very 

 minute ; radical ones 2 — 3 on each plant, attached to short recurved 

 peduncles, which originate from the tuft of leaves; terminal ones soli- 

 tary, nearly sessile between the bracleae (i. e. without any proper pe- 

 dicel). Calyx 5-partcd ; the divisions 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 corolla; filaments slender, adnate the lower two-thirds of 

 their length, smooth ; cells of the anthers approximated, subglobose. 

 Ovarx) ovate, acute, compressed, surrounded at the base with a minute 

 red disk, 2-cclled, many -seeded ; style rather larger than the ovary, subu- 

 late; stigma minute, bifid gt the summit. Capsule broadly obcordate, 

 compressed, opening along the edge at the summit; valves entire, con- 

 vex ; dissepiment adhering to the valves. Seeds 10 — 15 in each cell, 

 linear-oblong, fuscous, straight; embryo straight; cotyledons oblong, dis- 

 tinct ; radicle oblong.
