When it is stated that the “London Catalogue of British Plants”—meaning only the flowering plants and ferns—includes nearly 1,700 species, it will be understood that an inexpensive work for the pocket of the rambler can only give figures of a few of these; but the Author has tried to so use the 180 plants delineated that they may serve as a key to a much greater number of species. He regrets that technical difficulties connected with colour-printing and binding have made it impossible to carry out his original plan of grouping the plants according to their natural affinities; instead, he has had to arrange them more in seasons, a course which, after all, may be preferred by the rambler, who will thus find in contiguous pages the flowers he is likely to meet in the course of one ramble. The more scientifically inclined may find the species enumerated in the Natural Orders at the end of the work ([page 153]).
Several of the black and white figures are of trees which are not natives, but from the frequency with which they are now planted in woods and parks the question of their identity is constantly troubling the rambler, and it seems well to give him the power to decide what they are.
In conclusion, the Author would but express the hope that the present volume may receive a similarly encouraging reception to that which has been accorded to his previous efforts to popularize one of the most delightful branches of human knowledge.
WAYSIDE AND WOODLAND BLOSSOMS.
The Daisy (Bellis perennis).
So widely distributed and well known is this plant that surprise may be felt at its inclusion here; but its perfect familiarity marks it as a capital type of the important natural order to which it belongs. What is commonly known as the flower is really a corymb or level-topped cluster of many densely-packed florets of two kinds. Those of the central yellow disc consist each of a tubular corolla, formed by the union of five petals, within which the five anthers unite to form a sheath round the central pistil. The outer or ray-florets have the corolla developed into an irregular white flag, which at once renders the composite flower conspicuous and pretty. These outer florets produce pistils only, as though the extra material necessary for the production of the white flag had made economy in other directions a necessity, and had prevented the development of anthers and pollen.
This is the only British species of its genus, which derives its name from the Latin Bellus, pretty. Its second, or specific, name signifies that the plant lives for several years. It flowers nearly all the year round, and occurs generally in grassy places throughout the British Islands.
The Natural Order Compositæ, to which Bellis belongs, includes no less than forty-two British genera, which are divided into two series. Several of these genera will be illustrated and described in succeeding pages, but in all the flower-heads will be found to be constructed in the main after the manner of the Daisy. Some will be found to have no ray-florets, others to be composed entirely of ray-florets; and all these modifications of the type give the distinctive characters to the various genera.
