. Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. a b a b 1567. Cattleya. The light and shaded parts, a a and b b, each represent cue year's growth. The Orchid flower exhibits perhaps the greatest specialization and adaptation found anywhere in the vegetable kingdom. The 2 outer whorls of floral organs, the sepals and petals, have been sufficiently described. In the monocotyledons there are normally present 2 whorls of stamens. In the Orchids only 1 or 2 of these are fertile. In the Monandrro (Cypripedium, etc.) the odd stamen of the outer whorl is developed into a wing- like staminodium (Figs. 1568,1569, st). The similar sta- mens of the inner whorl are fertile, and form 2 anthers, 1 on each side of the staminodium (Figs. 1568, 1569, a). In all the other Orchids, except in abnormal cases, only the odd stamen of the outer whorl is fertile, bearing an anther situated at the toj) of the column (Fig. 1570, ft). The similar two of the inner whorl are developed as staminodia, forming the sides of the clinandrum or anther-bed. Often they are developed into crests or ears on the column. Traces of the other stamens are rarely foimd in the flower. Compare Figs. C-42-644, Vol. I. The 3 pistils are developed in Cypripedium and a few related genera. In these the stigma is clearly 3-lobed, showing the union of 3 pistils (Figs. 1568, 1569, s). In most of the other genera only 2 of the stigmas are receptive, the third being developed into the curious rostellum. In some cases the stigmatic surfaces are confluent into one, while in others they remain more or less distinct. Generally they appear as flat surfaces often sunken in a depression in the column (Lseliineffi, Fig. 1570, s, and many others). In a few cases the stigmas are more or less elevate
