PLANT LIFE.
General Work for Summer Months.—Study the forms and duties of leaves ([Chap. III.]); and the thickening of stems ([Chap. V.]). Examine, identify, and collect grasses ([Chap. VII.]) and summer flowers ([Chap. VI.]), and make observations upon cross-pollination of flowers by insects ([Chap. VI.]). Study the development and structure of fruits ([Chap. IX.]); and the life-history of ferns ([Chap. X.]). Compare and contrast mushrooms and toadstools ([Chap. XI.]).
Plants usually in flower.—Wallflower, shepherd’s purse, buttercup, anemone, meadow vetchling, common vetch, red clover, white clover, broom, wild rose, hawthorn, poison hemlock, cow parsnip, carrot, daisy, dandelion, speedwell, mullein, snapdragon, thyme, sage, red deadnettle, white deadnettle, lily of the valley, wild hyacinth, star of Bethlehem, rushes, sedges, sweet-scented vernal grass, slender foxtail, meadow foxtail, Timothy grass, Yorkshire fog, wild oat, annual meadow grass, smooth-stalked meadow grass, rough-stalked meadow grass, meadow fescue, sheep’s fescue, perennial rye grass, couch grass, lime, sycamore, and others.
