JULY. 275 
Involucre, or leaves under the umbel, of few divisions, those 
under the small umbels of many leaves. Stalks hollow. 
Cicuta virosa. Water Hemlock, or Cowbane. For- 
tunately this is not a very common plant, for it is a deadly 
poison to man, and though cattle are said to eat the young 
leaves, I imagine, from the name, that it is supposed to be 
injurious to them. It is an umbelliferous plant, appearing 
in ditches, and about the sides of streams. The stem is 
three or four feet high, hollow, and divided within by 
partitions, into cells. The leaves are twice divided, those of 
the root with more numerous divisions. Umbel of flowers 
proportioned to the size of the plant. 
PENTANDRIA. DIGYNIA. 
CALYCIFLORZ. APIACEX. 
HELOSCIADIUM. (Marsuwort.) 
Generic Character. See page 135. 
HELOSCIADIUM NODIFLORUM. Procumbent Marshwort. 
Stem procumbent, leaves divided into distinct leaflets, which 
are ovate, and cut at the edges, those of the root sometimes 
having a lobe at the base. Flowers small, in umbels, without 
stalks, opposite the leaves. Sides of lakes and rivulets.
