The elements of botany for The elements of botany for beginners and for schools elementsofbotany00gray Year: 1887 between petals and stamens. 246. That stamens are of the same general nature as petals, and there- fore a modification of leaves, is shown by the gradual transitions that occur between the one and the other in many blos- soms ; especially in cul- tivated flowers, such as Roses and Camellias, when they begin to double, that is, to change their stamens into pet- als. Some wild and natural flowers show the same interesting transitions. The Caro- lina Allspice and the White Water-Lily ex- hibit complete grada- tions not only between sepals and petals, but The sepals of our Water-Lily are green out- side, but white and petal-like on the inside ; the petals, in many rows, gradually grow narrower towards the centre of the flower; some of these are tipped with a trace of a yellow anther, but still are petals; the next are more contracted and sta- men-like, but with a flat petal-like filament; arid a further narrow- ing of this completes the genuine stamen. 247. Pistils and stamens now and then change into each other in some Willows; pistils often turn into petals in cultivated flowers; and in the Double Cherry they are occasionally replaced by small green leaves. Sometimes a whole blossom changes into a cluster of green leaves, as in the ' green roses ' occasionally noticed in gar- dens, and sometimes it degenerates into a leafy branch. So the botanist regards pistils also as answering to leaves; that is, to single leaves when simple and separate, to a whorl of leaves when conjoined. 229 Fia. 228. Series of sepals, petals, and stamens of White Water-Lily, showing the transitions. Fio. 229. A Cactus blossom.
