This is a complete and regular, yet simple flower; and will serve as a pat- tern, with which a great variety of flowers may be compared. 193. When we wish to desimate the leaves of the blossom by one Avord, we call them the Perianth. This name is formed of two Greek words meaning " around the ; It is convenient to use in cases where (as in the Lilies, illustrated on the first page) we are not sure at first view whether the leaves of the flower are calyx or corolla, or both. 194. A Petal is sometimes to be distin- guished into two parts; its Blade, like the blade of a leaf, and its Claio, which is a kind of tapering base or foot of the blade. More commonly there is only a blade; but the petals of Roses have a very short, nar- row base or claw; those of Mustard, a longer one ; those of Pinks and the like, a narrow claw, which is generally longer than the blade (Fig. 308). 195. A Stamen, as we have already learned (15, 17), generally consists of two parts ; its Filament and its Anther. But the filament is only a kind of footstalk, no more necessary to a stamen than a petiole is to a leaf. It is therefore sometimes very short or wanting; when the anther is sessile. The anther is the essential part. Its use, as we know, is to produce pollen. 196. The Pollen is the matter, looking like dust, which is shed from the anthers when they open (Fig. 159). Here is a grain of pollen, a single particle of the fine powder shed by the anther of a Mallow, as seen highly magnified. In this plant the grains are beset with bristly points ; in many plants they are smooth; and they diflTer greatly in appearance, size, and shape in different species, but are all just alike in the s
