Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches, and a synopsis of the vegetable kingdom. Gardening -- Dictionaries; Plants -- North America encyclopedias. 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 muki- 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. Ij. minor is said to flower more frequently than any other northern species. Details of its flower are shown in Pig. 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 fls. and the pistil a third flower. Duckweeds are perennial plants. In the autumn they fall to the botlom of the ditch or pond, but rise again in the spring, and increase in size. The allied genus Wolffia contains the smallest flowering plants in the vegetable kingdom. There are about 11 spe- cies of Duckweeds, widely scattered. rhiza is commonly known in American botan- ies as Spirixhln polyrhiza, but Spirodela is considered by Bentham and Hooker a sub- genus of Lemna. 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 sufficient numbers to clear oil the remainder. ns 7-11: roots several. poIy
