SCROPHULARIACE^:. (FIGWORT 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 ptKpos, 

 small, and avde p.ov^ flower. ) The section HEMIANTHUS (from rjp.i, half, and 

 avdos, 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. Nuttallii. (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 bell-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 tilament itself; stigmas subulate. 

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



14. LIMOSELLA, 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. aquatica, L. : var. tenuif61ia, 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. SYNTHYBIS, Benth. SYNTHYKIS. 



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 crui>, together, 

 and 6vpis, a little door ; evidently in allusion to the closed valves of the pod.) 



1. S. Houghtoniana, 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, with the upper 

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

 the others.
