 and common northward. June. Seeds surrounded with jelly. (Eu.) 



4. SYMPLOCARPUS, Salisb. SKUNK CABBAGJS. 



Spathe hooded-shell-fonn, pointed, very thick and fleshy, decaying in fruit, 

 Spadix globular, short-stalked, entirely covered with perfect flowers which are 

 thickly crowded and their (1-celled or abortively 2-celled) ovaries immersed in 

 the fleshy receptacle. Sepals 4, hooded. Stamens 4, opposite the sepals, with 

 at length rather slender filaments : anthers extrorse, 2-celled, opening length 

 wise. Style 4-angled : stigma minute. Ovule solitary, suspended, anatropous. 

 Fruit a globular or oval mass, composed of the enlarged and spongy spadix, en- 

 closing the spherical seeds just beneath the surface, which is roughened with the 

 persistent and fleshy sepals and pyramidal styles. Seeds filled by the large 

 globular and fleshy conn-like embryo, wliich bears one or several plumules at the 

 end next the base of the ovary : albumen none. Perennial herbs, with a strong 

 odor like that of the skunk, and also somewhat alliaceous ; a thick descending 

 rootstock bearing a multitude of long and coarse fibrous.roots, and a cluster of 

 very large and entire veiny leaves, preceded by the nearly sessile spathes. 

 (Name from a-upirXoKT], connection, and xapiros, fruit, in allusion to the coales- 

 cence of the ovaries, &c. into a compound fruit.)

 Moist grounds ; common. March, April. Spathe spotted and striped with 

 purple and yellowish-green, ovate, incurved. Fruit ripe in September, forming

 embryo.
