1. I. gratioloid.es, 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. 



■\Vet places, in the Sierra Nevada (Lcmmon) : 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. Mudwobt. 



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

 nearly regular. Stamens 4, nearly equal : anthers conliuently 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 tieshy leaves, in clusters around the 

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

 tered alternate. Flowers small : corolla white or purplish. 



1. L. 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, Lcmmon), 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- 

 men, 2, inserted "ii the upper side of the throat (rarely a lower pair inserted near 

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

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

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

 iii,ni\ seeded placenta. — Perennial herbs (all North American, and chiefly west- 

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

 or raceme of -mall 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 : .-cape when in blossom hardly surpassing the leaves (.'! to S inches 



high), bearing a short and loose racen f several Bowers: corolla "blue,"abou( 



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

 Scroph. I ad. ; Book f'l. ii. t. 171. 



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

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