as the gift of genius in families. You cannot tell which the
fragrant ones are till you try them. Sometimes it is the large white ones, sometimes the large purple ones, sometimes the small pink ones. The odor is faint and recalls that of the sweet violets. A correspondent, who seems to have carefully observed these fragrant hepaticas, writes me that this gift of odor is constant in the same plant; that the plant which bears sweet-scented flowers this year will bear them next." It is not evident that insect aid is necessary to transfer the tiny, hairy spiral ejected from each cell of the antherid, after it has burst from ripeness, to the canal of the flask-shaped organ at whose base the germ-cell is located. Perfect flowers can fertilize themselves. But pollen-feeding flies, and female hive bees which collect it, and the earliest butterflies trifle about the blossoms when the first warm days come. Whether they are rewarded by finding nectar or not is still a mooted question. Possibly the papillae which cover the receptacle secrete nectar, for almost without exception the insect visitors thrust their proboscides down between the spreading filaments as if certain of a sip. None merely feed on the pollen except the flies and the hive bee. The SHARP-LOBED LIVER-LEAF (Hepatica acuta) differs chiefly from the preceding in having the ends of the lobes of its leaves and the tips of the three leaflets that form its involucre quite sharply pointed. Its range, while perhaps not actually more westerly, appears so, since it is rare in the East, where its cousin is so abundant; and common in the West, where the round-lobed liver-leaf is scarce. It blooms in March and April. |
