We have seen how diversified are the movements of climbing plants. These plants are numerous enough to form a conspicuous feature in the vegetable kingdom; every one has heard that this is the case in tropical forests; but even in the thickets of our temperate regions the number of kinds and of individual plants is considerable, as will be found by counting them. They belong to many and widely different orders. To gain some crude idea of their distribution in the vegetable series, I marked from the lists given by Mohl and Palm (adding a few myself, and a competent botanist, no doubt, could add many more) all those families in _Lindley’s Vegetable Kingdom_, which include plants in any of our several subdivisions of twiners, leaf-climbers, and tendril-bearers; and these (at least some of each group) all have the power of spontaneously revolving. Lindley divides Phanerogamic plants into fifty-nine alliances; of these, no less than above half, namely, thirty-five, include climbing plants according to the above definition, hook and root-climbers being excluded. To these a few Cryptogamic plants must be added which climb by revolving. When we reflect on this wide serial distribution of plants having this power, and when we know that in some of the largest, well-defined orders, such as the Compositæ, Rubiaceæ, Scrophulariaceæ, Liliaceæ, etc., two or three genera alone, out of the host of genera in each, have this power, the conclusion is forced on our minds that the capacity of acquiring the revolving power on which most climbers depend is inherent though undeveloped in most every plant in the vegetable kingdom. FLOWER COLORATION --ALEXANDER S. WILSON The Prophet-plant (Arnebia echioides) is a native of Persia and Arabia, but has been introduced and grows freely in gardens in England. Its chief interest lies in its variable flowers, which may fairly rank with those of the changeable Hibiscus and other “Plants divine and strange That every hour their blossoms change.”
