6 MENYANTHES Tourn. L. Gen. n. 202. 



Perennial herbs with chiefly radical leaves, and white flowers 

 on erect scapes or scape-like peduncles. Calyx 5-parted. Co-

 widely spreading, fimbriate or crested on the inner face. Stamens 

 5, inserted on the tuhe of the corolla; filaments filiform; anthers 

 sagittate, versatile. Ovary one-celled ; style long and slender ; 

 stigma bilamellate. Capsule oval, indehiscent, but bursting irreg- 

 ularly across the top. Seeds rather few and large, orbicular and 

 compressed ; the close crustaceous coat smooth. 



M. trif&Iiata L. Sp. 145. Scapes and leaves stout, 6-10 inches long,

 petioled; leaflets oblong or obovate, entire or repand, obtuse at the apex, 

 narrowed to a sessile base, pinnately veined, 1-3 inches long: raceme 

 borne on a long scape-like naked peduncle, 10-20-flowered : pedicels stout, 

 3-12 lines long, bracteolate at the base: flowers 5-7 lines long: corolla

Order LXIII POLEMONIACEAE DC. Fl. Franc, iii, 645. 



Herbaceous or rarely shrubby plants with bland colorless juice, 

 simple or divided leaves without stipules and perfect regular 

 flowers with a free ovary and hypogynous disk. Calyx 5-parted 

 or 6-lobed, imbricated in the bud, persistent. Corolla 5-lobed, 

 dextrorsely convolute and not plicate in the bud. Stamens 5, 

 distinct, inserted on the tube of the corolla, alternate with its 

 lobes. Style one, 3-lobed, or 3-cleft and stigmatic down the inner 

 face. Fruit a 3-celled loculicidal capsule, usually with a thick 

 placental axis; and few or many small amphitropous or nearly 

 anatropous seeds with a thin or soft coat, commonly developing 

 mucilage when wetted. Embryo straight and rather large, in 

 the axis of a fleshy or harder albumen. Cotyledons flat or flat- 

 fish and rather broad.
