The minute white auxiliary and pistillate flowers have 4 stamens and develop 4 car- pels. Small hairlilce white bracts are borne at the base of the leaves and among the flowers. The finely pinnate, brilliantly green leaves and their graceful habit in growing above the water has made this a very desirable plant, but it is an indifferent oxygenator, as the sub- merged leaves soon slough off and the rapidly growing plant sends its green crown of leaves 4 to 6 inches ° FIG. no.

It is a beautiful semi-aquatic plant, and is extensively grown in watertight hang- ing baskets or jars where the fine single stems hang over the sides in handsome festoons. In addition to the above described form there are two species of true Proserpinaca found in the United States, viz, P. palustris and P. fectinata, gener- ally distributed in the Southern States. Proserpinaca palustris (Linn.) or Common Mermaid-weed, Fig. 117, is not an indigenous plant but is now native to swamps from New Brunswick to Lake Huron and south to Florida, Iowa, Cuba and Central America. It is an aquatic herb with single stem apd alternate dentate leaves about a weak stem. The perfect flowers are stigmatic above the middle with 3 or 4 styles, and the bony fruit has one seed in each.
