found this plant with the water-hemlock, which is very poisonous, 

 and which it greatly resembles, although flowering earlier in the 

 year. The generic name is from two Greek words which signify 

 scent and root. 



WATER-PARSNIP. 



Sium cicutczfolium. Parsley Family (p. 15). 



Two to six feet high. Stem. Stout. Leaves. Divided into from three 

 to eight pairs of sharply toothed leaflets. Floivers. White, in compound 

 umbels. 



This plant is found growing in water or wet places through- 

 out North America. 



ARROW-HEAD. 



Sagittaria variabilis. Water-plantain Family. 



Scape. A few inches to several feet high. Leaves. Arrow-shaped. 

 Flowers. White, unisexual, in whorls of three on the leafless scape. Calyx. 

 Of three sepals. Corolla. Of three white, rounded petals. Stamens and 

 Pistils. Indefinite in number, occurring indifferent flowers, the lower whorls 

 of flowers usually being pistillate, the upper staminate. 



Among our water-flowers none are more delicately lovely than 

 those of the arrow-head. Fortunately the ugly and inconspic- 

 uous female flowers grow on the lower whorls, while the male 

 ones, with their snowy petals and golden centres, are arranged 

 about the upper part of the scape, where the eye first falls. It is 

 a pleasure to chance upon a slow stream whose margins are bor- 

 dered with these fragile blossoms and bright, arrow-shaped leaves. 



WATER-PLANTAIN. 



Alisma Plantago. Water-plantain Family. 



Scape. One to three feet high, bearing the flowers in whorled, panicled 

 branches. Leaves. From the root, oblong, lance-shaped or linear, mostly 

 rounded or heart-shaped at base. Flowers. White or pale pink, small, 

 in large, loose clusters which branch from the scape. Calyx. Of three se- 

 pals. Corolla. Of three petals. Stamens. Usually six. Pistils. Many, 

 on a flattened receptacle. 



The water-plantain is nearly related to the arrow-head, and 

 is often found blossoming with it in marshy places or shallow 

 water,
