Synthyris. SCROPHULARIACE^E. 571 



1. I. gratioloides, Benth. Diffusely branching, about a span high : leaves 

 ovate or oblong, sparingly toothed or entire : peduncles mostly twice the length of 

 the leaves, divergent in fruit : corolla violet or purple, 3 or 4 lines long. Capraria 

 gratioloides, Linn. 



Wet places, in the Sierra Nevada (Lemmon) : thence to Oregon and through the Atlantic 

 States : also in S. America. Occurs on the coast of France, but probably a casual introduction. 



13. LIMOSELLA, Linn. MUDWORT. 



Calyx campanulate, 5-toothed. Corolla between rotate and campanulate, 5 -cleft, 

 nearly regular. Stamens 4, nearly equal : anthers confluently 1-celled. Style short, 

 club-shaped : stigma thickish. Capsule globose, many-seeded, 2-valved ; the edges 

 of the valves separating from the delicate or evanescent partition : the thick placenta 

 left in the axis. Diminutive and glabrous annuals, rooting and creeping in mud, 

 especially when saline ; with narrow entire fleshy leaves, in clusters around the 

 simple 1-flowered peduncles or scapes, and at the end of the runners, or when scat- 

 tered alternate. Flowers small : corolla white or purplish. 



1. Li. aquatica, Linn. An inch to a span high : petioles longer and in water 

 much longer than the linear or spatulate-oblong or oval blade, and longer than the 

 peduncles. 



Along the sea-shore, also in and beyond the Sierra Nevada, in brackish mud or sand, or in 

 apparently fresh water ; thence to the Rocky Mountains. Common in the Old World. In 

 our broadest-leaved form (Sierra Valley, Lemmon), the blade is two thirds of an inch long and 

 one third wide, in the narrower and smaller less than a line wide. L. tenuifolia,, Nutt., which 

 takes its place in the Atlantic States and in the southern hemisphere, has fleshy petioles with 

 no distinct blade. 



14. SYNTHYEIS, Benth. 



Calyx 4-parted. Corolla campanulate, with 4 slightly spreading more or less 

 unequal lobes, or sometimes divided irregularly, sometimes wholly wanting. Sta- 

 mens 2, inserted on the upper side of the throat (rarely a lower pair inserted near 

 the base of the corolla on the lower side) : anthers 2-celled ; the cells parallel and 

 distinct. Style slender : stigma small, undivided. Capsule flattened, obtuse or 

 emarginate, loculicidal; the valves cohering below by the partition to the central 

 many-seeded placenta. Perennial herbs (all North American, and chiefly west- 

 ern), with alternate and crenate leaves, the radical roundish or cordate, and a spike 

 or raceme of small purplish or greenish flowers, terminating a leafy stem or a naked 

 scape. 



1. S. reniformis, Benth. Slightly hairy or glabrous : leaves all radical, round- 

 reniform, thin : scape when in blossom hardly surpassing the leaves (3 to 8 inches 

 high), bearing a short and loose raceme of several flowers : corolla " blue," about 

 twice the length of the calyx. DC. Prodr. x. 454. Wulfenia reniformis, Benth. 

 Scroph. Ind.; Hook. Fl. ii. t. 171. 



Var. cordata : a form with rather coriaceous and smaller leaves ; the blade an 

 inch long and ovate-cordate : probably growing in a more exposed situation. 



The species occurs in the woods of Oregon. This variety, on gravelly hillsides, Red Mountain, 

 Mendocino Co., Kellogg. 



S. RUBRA, Benth. 1. c. (Gymnandra rubra, Hook. 1. c. 103, t. 172), belongs to Oregon, but 

 may inhabit the northern part of the State. It is stouter and coarser, pubescent when young, 

 has ovate or oblong thickish leaves, those of the flowering stem several and sessile, the flowers in 

 a dense spike and destitute of corolla. The other species are more eastern.
