Gardening. LEMON plant commonly consisting of one leaf and one un- branched root which has no vascular tissue. These lvs. are called fronds by the botanist largely because lvs. do not ordinarily emit roots. The plants grow separ- ately, or cohere by their edges in 2's or 3's, and multi- ply by similar fronds, which grow out of the edges of the old ones something like buds. The flowers are minute and appear on the edge of the frond. They consist of a pistil and generally 2 stamens which are inclosed in a sheath, which the botanists have determined is a spathe by reason of the place where it is borne and by homology with related plants. L. minor is said to flower more frequently than any other northern species. Details of its flower are shown in Fig. 1260,where there seem to be 4 anthers, but there are only 2, each bearing 2 locules. Some botanists consider the 2 stamens as 2 Hs. and the ).iiitil a third flower. Duckweeds are pcinnnal plants.

The common Duckweed occasionally infests the small lily ponds (arti- ficial ones), where it is a pest. The simple remedy is to flush the pond and see that com- mon goldfish or carp are in sufiicient numbers to clear off the remainder. A.
