MonANDRIA. MONOGYNIA. 
CALYCIFLOR2. HALORACE. 
HIPPURUS. (Maryz’s 7,11.) 
Generic Character. Calyx simple and superior, forming a very 
indistinct rim. Fruit a small one-celled nut. 
Hiprurus vutearis. (Plate XI. Fig. 44.) Common 
Mare’s tail. A very singular plant, and the first that makes 
its appearance in this class. There is only one species, and 
it is so unlike any other plant, except perhaps Lguisetum, 
mentioned at page 118, that when found it is easily recog- 
nized. It has a long stem, erect, simple, and jointed. 
Leaves in whorls of about eight, narrow and small. Flowers 
very small, and at the base of each of the upper leaves. The 
small rim in the place of calyx and corolla, encloses the 
pistil and one stamen, which has a large two-lobed anther. 
it grows in ditches and stagnant waters.
