RIVER BANKS— BROOKS— RUNNING STREAMS 7 



Sepals, 5, green or greenish yellow. No petals. Stamens, 

 10. Pistils, 5. ^ to 2 feet high. 



The fruit is made up of the 5 united pistils, and is at length a 

 capsule with 5 beaks. The flowers grow on the upper side of a 

 leafless stem, the terminal blossoming first. 



8. Tillaea 



Tilla%a simplex. — Family, Orpine. Color, greenish white. 

 Leaves, on the stem, opposite ; at the root, clustered, entire, 

 fleshy. Time, summer. 



A symmetrical flower ; petals, sepals, stamens, andpisfils, 3 or 4. 



A queer little mud-loving plant. The tiny 2-inch-high stem 

 bears very small, single flowers in the leaf-axils. 



9. Meadow Parsnip 



Thaspium barbinode. — Family, Parsley. Color, yellow. 

 Leaves, twice or thrice compound, alternate; those near the 

 base less divided than those higher up on the stem. Leaflets, 

 long, narrow, somewhat ovate, coarsely toothed. Time, May 

 June. 



The flowers of plants belonging to this family grow in umbels 

 which are frequently compound, forming umbellets. They pos- 

 sess oil-tubes — minute canals running lengthwise of the fruit — 

 containing aromatic oil, which can only be seen with a strong 

 microscope. , 



The style and its stigma develop in advance of the stamens, 

 thus preventing self-fertilization. Insects carry the pollen of one 

 flower to the stigma of another, both of which happen to be ripe 

 at the same time. 



The stems are generally hollow. 

 * The plants vary in size and color, but nearly all have the umbel 

 form of blossom and the compound leaves. The flowers are so 

 minute they are difficult to study. A professional botanist said 

 that he had found life too short to spend over the parsleys. 



The fruit is single-seeded, like the familiar fennel and caraway-
