. Our native trees and how to identify them : a popular study of their habits and their peculiarities . Trees. MAPLE FAMILY Stamens.âThree to seven, hypogynous ; filaments long and slen- der in the sterile flowers, short in the fertile. Anthers reddish, ob- long, two-celled ; cells opening longitudinally. Pistils.âIn sterile flowers rudimentary ; in fertile, ovary borne on narrow disk, superior, downy, two-lobed, two-celled, compressed contrary to the dissepiment, wing-margined ; styles two, united at base only, long, exserted, red ; ovules two in each cell, one usually aborts. Fruit.âTwo samaras united forming a ,maple key. Borne on slender drooping pedicels an inch and a half to three inches long. Vary in length from one and one-half to three inches. Wings di- vergent, straight or curved, three-fourths of an inch broad, deep. Staminate and Pistillate Flowers of Silver Maple, r^4cer sacc/iarttium. red or pale chestnut brown. Seed reddish brown. April, May. Cotyledons thin, leaf-like. Seed germinates as soon as it falls to the ground. The seed of .'leer usually ripens in the autumn and germinates the fol- lowing spring. The seed of the two An^erican species with precocious flowers, .â i. rubrum and A. Saccharinum. however, ripens at the end of a few weeks after the trees flower, and germinates at once. This is a provision, perhaps, acquired by these species to insure their perpetuation ; they grow in low, wet land, often inundated during the winter, and the seed, if it ripened in the autumn would often lie in the w^ater through the winter and be in danger of losing its vitality ; but it reaches the ground after the water has fallen in the swamps and before the exposed surface of the ground has become baked by the hot sun of summer, that is, when it is just in the condition to insure the germination of seed. âCharles S.
