Plants and their ways in South Africa . Fig. 249.—Polystachya Otfoniana, Reichb., an epiphytic genus with tuberi-form stem bases. The flowers are yellow. delicately tinged with purple. Leaf solitary, radical, flat on the soil. , R. Br., extends from the Cape peninsula to in November and December. Satyrium is distinguished from other Orchids by the twospurs of the hood-shaped lip at the back of the fiower ( to the stalk). The sepals and two petals form the lowerportion of the flower. The anther is in front, as the ovary is 2/8 Plants and their Ways in South Africa not twisted, and the glands of the pollinia lie in the notchedrostellum. Leaves two or one lying flat on the ground, or more thantwo erect. Flowers in dense spikes, white, brilliant yellow,orange, or a beautiful rose colour or dull brown. Differentspecies may be found in flower from July to December. Awidely distributed Fig. 250.—Mystacidiumfilicorne, Lindl. An epiphytic Orchid with aerialroots. Satyridium is distinguished from Satyrium by the pollenmasses being attached to a single gland. There is but onespecies, S. rostratum, Lind. Disa.—Sepals nearly equal and separate ; the odd one,which is at the back, and forms the conspicuous part of theflower, is helmet-shaped, i-spurred, or saccate. The lip inmost species is small. In the blue Disa it is quite leafy, or the leaves reduced to bracts. Roots tuberous. Classification of Plants 279 D. uniflora^ Berg. (usually\called ^^<3!/2^/)f(irrt) is the finest one,although others are quite beautiful if less showy. In Flora Capensis, the species oiDisa with the lip posteriorare separated to form the genus Orthopenthea.
