392 THE RIVER-SIDE NATURALIST. 



John Jerome Zannichelli, a Venetian apothecary and botanist. 

 Flowers August. 



The HEMP or WATER- AGRIMONY (Eupatorium cannabinum) 

 Fig. in " E. B.," 785 is common enough on the banks of 

 rivers and other watery places. Stems from three to four 

 feet high, very tough and unwieldy, leaves downy. Three 

 to five partite, middle lobe the longest and opposite. 

 Flowers very numerous, of a pale reddish-purple, thickly 

 crowded into tufts, terminating the stem and upper 

 branches. Flowers July and August. 



The COMMON FLEA-BANE or HERB CHRISTOPHER (Pulicaria 

 dysentericd) Fig. in " E. B.," 770 from putex, a flea ; the 

 powerful smell being obnoxious to fleas. The stem rarely 

 exceeds two feet in height, is firm, solid, and cottony, 

 more or less branched. Leaves spreading, dull green 

 above, whitish underneath, and cottony. Flowers yellow 

 at the top of the stem, two or three together. Flowers 

 July to October. 



It is said that the Russian soldiers, in their expedition 

 to Persia under General Keil, were cured of dysentery by 

 this plant ; whence Linnaeus gave it the specific name of 

 Dysenterica. 



There is another plant which goes by the name of FLEA- 

 BANE (Erigerori), but this never grows near the water. 



The MARSH WOUNDWORT or ALL-HEAL (Stachys palustris) 

 Fig. in " E. B.," 1669 named from a-ra^y?, a spike, from 

 the form of the inflorescence. The English names Wound- 

 wort, All-Heal^ arise from its high repute in former times 

 as a vulnerary. The stems rise about two feet in height. 

 The leaves are placed opposite each other, and close to the 

 stem ; silky above, downy beneath. The flowers are of 

 pale purple variegated with violet and white, in whorls on 

 the spike, with eight or ten flowers in each whorl. Flowers 

 August. 



Some of the Mints are also found by the margin of rivers 

 and lakes, particularly the TALL RED MINT (Mentha rubrd) 

 Fig. in " E. B.," 1033. The stem rises at times as high 

 as from four to five feet. The flowers are purplish-red, the 

 leaves are stalked and smooth. Flowers September.
