SAURUKA'CEjE, L'zardt-Tatit, a natural order of Plants be- 

 longing to the Achlamydose group of Incomplete Kxogens. It 

 consists of only a few genera, which arc aquatic or marshy herbs 

 or herbaceous plants, with perennial root-stocks, knotted stems, and 

 simple entire alternate leaves, with vaginal stipules. The flowers are 

 naked, and seated upon a scale. The stamens are 6 in number, hypo- 

 gynous; filament slender; anthers continuous with the filament, 

 having 2 lobes bursting longitudinally; the ovaries are 4, containing 

 one or more ovules; style short; stigma simple ; the seeds are few, 

 with an abundant albumen, in the midst of which lies a small embryo, 

 which is inclosed in a persist- nt vitellus. 



These plants are very near Piperacea, from which they mostly 

 differ in the compound nature of their ovary. This order connects 

 Dicotyledons with Monocotyledons. Its foliage, stipules, and seeds 

 connect it with the former ; but the floating habit of some of the 

 species, and their general character, ally them with some of the families 

 of the latter class. They are natives of North America, China, the 

 north of India, and the Cape of Oood Hope, where they are found 

 growing in marshes and pools of water. Their properties are not
