SCEOPHULARIACEiE. (fIGWOET FAMILY.) 331 



white or purplish flowers solitary in the axils of some of the middle leaves (usu- 

 ally one axil floriferous, that of the other leaf sterile). (Name formed of fUKpos, 

 small, and SivBtfiov., flower.) — The section HemiAnthus (from ijfii, half, and 

 avBos, flower) includes the species like ours, of which there are several dis- 

 covered by C. "Wright in Cuba, having the upper lip of the corolla very short 

 or obsolete, and mostly slender or subulate stigmas. 



1. M. Nutt^llii. (Hemianthus micranthemoides, Nutt.) Branches as- 

 cending, l'-2' high; leaves obovate-spatulate or oval; peduncles at length 

 recurved, about the length of the calyx, which is beU-shaped, 4-toothed and 

 usually split down on one side, in fruit becoming pear-shaped ; middle lobe of 

 the corolla linear-oblong, nearly twice the length of the lateral ones ; appen- 

 dage of the stamens nearly as long as the filament itself ; stigmas subulate. — 

 Tidal muddy bands of the Delaware River, and southward. Aug. - Oct. 



14. LIMOSEIiIiA, L. MuDwoRT. 



Calyx bell-shaped, 5-toothed. Corolla short, widely bell-shaped, 5-cleft, nearly 

 regular. Stamens 4 : anthers confluently 1-celled. Style short, club-shaped. 

 Pod globular, many-seeded ; the partition thin and vanishing. — Small annuals, 

 growing in mud, usually near the sea-shore, creeping by slender runners, with- 

 out ascending stems ; the entire fleshy leaves in dense clusters around the simple 

 1-flowered peduncles. Flowers small, white or purplish. (Name a diminutive 

 of limus, mud, in which these little plants delight to grow. ) 



1. L. aqu^tica, L. ; var. tenuifdlia, Hoffm. Leaves (with no blade 

 distinct from the petiole) awl-shaped or thread-form. (L. tenuifolia, Nutt. L. 

 subulata, Ives.) — In brackish tidal mud, from New Jersey northward. Aug., 

 Sept. —Plant l'-2' high. (Eu.) 



15. Sl'NTHTRIS, Benth. Stnthteis. 



Calyx 4-parted. Corolla somewhat bell-shaped, variously 2 - 4-lobed or cleft. 

 Stamens 2, inserted just below the sinuses on each side of the upper lobe of the 

 corolla, occasionally with another pair from the other sinuses, exserted : anther- 

 cells not confluent into one. Style slender : stigma simple. Pod flattened, 

 rounded, obtuse or notched, 2-grooved, 2-celled (rarely 3-lobed and 3-celled), 

 many-seeded, loculicidal ; the valves cohering below with the columella. — Per- 

 ennial herbs, with the simple scape-like stems beset with partly-clasping bract- 

 like alternate leaves, the root-leaves rounded and petioled, crenate. Flowers 

 in a raceme or spike, with bracted pedicels. (Name composed of (tvv, together, 

 and Svpis, a little door; cridently in allusion to the closed valves of the pod.) 



1. S. Houghtoni^na, Benth. Hairy; root-leaves round-ovate, heart- 

 shaped; raceme spiked, dense (5'- 12'); corolla not longer than the calyx, 

 usually 2-3-parted. — High prairies and hills, Wisconsin, Houghton, Lapham. 

 Michigan, Wright. Illinois, Mead. May. — Corolla greenish-white, for the 

 most part deeply 2-parted, with the upper lip entire, a little longer and narrower 

 than the lower, which is 3-toothed ; but occasionally 3-parted, vntb. the upper 

 lip notched or 2-lobed. When there are 4 stamens the lower are later than 

 the others.
