. Some ornamental shrubs for the Tropics. Shrubs Tropics. 26 CIRCULAR 34, FEDERAL EXPERIMENT STATION holding their shape best if regularly sheared. Plantings around the base of buildings are brightened by the almost continuous flowering of this shrub. It tolerates a considerable range of soils and light conditions. The blue, pink, or white flowers grow singly out of a pair of large axillary bracts whose margins are tipped by large stiff hairs. The 2- to corolla consists of a slender funnel and 5 lobes, one wider and more deeply cut than the others. The opposite leaves are 2 to 4 inches long on short petioles. The leaf surfaces and young stems have very short hairs more easily felt than seen. A pair of needle-shaped stipules nearly half an inch long arise at the base of each leaf. Propagation is by soft stem cuttings or seeds when Figure 8.—The railway fence, Bauhinia pauletia, has peculiar greenish flowers with petals reduced to short threads, and sepals twisted into a spiral. Bauhinia pauletia Pers. Railway Fence "Arafia Gato" (fig. 8) Leguminosae This bauhinia occurs in Central and northern South America and in some of the West Indies. It is normally a long branched, spiny shrub but occasionally reaches the proportions of a small tree. It is useful as a barrier if pruned to increase branching. Otherwise, it serves as background material and as a floral oddity. It is capable of growing in arid regions, and thrives in full sun- light. The flowers form on the ends of branches in the fall. The slender buds are to inches long. On opening the calyx splits along one side and then rolls into a spiral. The petals are reduced to mere.
