Uragoga, Mitreola is to Ophiorrhiza, growing in the warm regions of Asia and Oceania : the unilateral inflorescences are there the same as in Mitreola and the form of the capsules is nearly always the same. But the receptacle being more concave, the ovary and fruit are in great part inferior, and at a certain height on the , sides of the latter (tig. 321) are seen the re- mains of the calyx and a trace of the margin of the receptacular cup on which, the perianth was inserted. Some Ophior- rhizas, as Polyura and Palcenhamia, differ some- what from the rest in the turbinate or obconical form of the receptacle or in some details of the inflorescence which always consists of uniparous cymes. SpiradicUs is also a herb of tropical Asia, with flowers in racemiform often unilateral cymes. The concave receptacle OphiorrMzaJapomoa. is generally traversed by four ridges, and the lobes of the corolla, four or five in number, arevalvate. The ovary has two cells, some- times incomplete, sur- mounted by a disk with two or four lobes, and the placentas, ascending and plurioyulate, are those of Ophiorrhiza, Oldenlandia, &c. The fruit is a loculicidal capsule the valves of which often separate in two halves. Lerchea, shrubby or subshrubby plants of tropical Oceania, have the flowers of Oldenlandia, a fruit of two indehiscent cocci, with a corolla often glabrous within and stylary branches thicker than in those named Xanthophytum. In the latter the glomerules or floral cymes are inserted in the axil of the leaves, whilst in the true Lerchea, in which.
