Anacardium con- sists of trees from tropical America. In Semecarpus, an Asiatic tree with simple leaves, the dry fruit is also supported by a thick fleshy base, formed by the hypertrophy of receptacle, which is more or less concave, so that, like the perianth, the five stamens are in this genus hypogynous or peri- gynous to various degrees, and the ovary surmounted by three style branches. In Nothopegia^ a tree from the mountains of India, the flowers are tetramerous, with double imbricate perianth, and four stamens inserted on the edge of the disc ; but the ovary is sur- mounted by a short simple style, and contains a nearly apiculate, descendent ovule. The fruit is a depressed apiculate drupe. The leaves are simple and alternate, and the flowers arranged in com- pound clusters, but slightly ramified. Campnosperma has the same general organisation as the preceding genera, with three to four partite flowers, an imbricate corolla and a diplostemonous androceum. The ovule is descendent, with superior micropyle. But its fruit presents this peculiarity that it is divided by a false descendent partition into two unequal compartments. Cam- pnosperma consists of trees with alternate and simple leaves. The inflorescence often has the priacipal axis unramifled. These plants have been observed in tropical Asia, Madagascar, and even in Brazil, if. Fig. 324.
