ORDER CXI. ARACE^E. 



Perennial glabrous herbs, with large radical or alternate leaves, and perfect or 

 usually monoecious or dioecious flowers sessile and crowded on a spadix, which is 

 surrounded by a simple spathe ; perianth none, or 4 6-sepaled in perfect flowers ; 

 fruit a berry, 1 - 4-celled, 1 - many-seeded : seeds mostly albuminous, minute. 



A large order, but mostly tropical and scarcely represented in California. About half a dozen 

 species, of nearly as many genera, are found in the Atlantic States and northward. 



1. LYSICHITON, Schott. 



Spathe sheathing at base, with a broad colored lamina or none, at first enveloping 

 the cylindrical spadix, which becomes long-exserted upon a stout peduncle. Flowers 

 perfect, crowded and covering the spadix, with 4-lobed perianth, and 4 stamens 

 opposite the segments. Filaments short, flat ; anthers 2-celled, opening upward. 

 Ovary conical, 2-celled, 2-ovuled : stigma depressed : ovules horizontal, orthotropous. 

 Fruit fleshy, somewhat immersed in the rhachis and coalescent. Acaulescent
