The surface of the seeds is hispid, and the flowers, rather large, are axillary, solitary, or grouped in few-flowered cymes. Adenaria (flg. 396, 397) comprises also tropical American plants; like Dodecas, they have an obconioal or oampanulate receptacle, four or five sepals, without accessory tongues, and a diplostemonous androecium inserted higher or lower on the internal wall of the re- ceptacle. The ovary, with short foot, has two multiovulate cells, ^*~''*'' '"''''"''''"'â and the capsular fruit is obovoid, with an indefinite number of glabrous seeds. The two or three adenarias known are trees with opposite leaves and with axillary corymbiform and many- flowered cymes. Nearly all the parts are covered with dark punctiform glands, Very little difi"erent from Adenaria is Gris- lea secunda, a shrub of Columbia and Yenezuela, but it has dentiform tongues alternating with its four or five sepals, and all the stamens are inserted-quite at the base of the gynsecium. Its capsular fruit is globular, with seeds equally glabrous. In Woodfordia floribtmda, a shrub of India, China, Madagascar, and tropical eastern Africa, which has been referred to the genus Grislea, there are also black glandular points on the greater part of the organs ; but the flowers are not regular. The receptacular tube has an oblique superior opening, and the flower as a whole is bent. There are from five to seven dentiform valvate sepals, with as many small accessory tongues and very small petals. The stamens are declinate, twice as many as the sepals, in two verticils, and the largest oppositipetalous. The fruit is a loculicidal bivalve capsule, with numerous seeds, covered with hairs or papillae. This genus also closely connects Lythrum with the following type. Guphea (fig. 398-404), which c
