[Illustration] This plant inhabits the equatorial regions of South-America, the provinces of Para, Rio-Negro, and the neighborhood of the Amazon, where it is very frequent. It resembles the hura crepitans; its leaves are alternate, somewhat cordate, rounded, glabrous, serrate; rolled up and stipulate while young. The petiole is provided at its top with two large glands. Flowers monoïchous; the male flowers having a short, urceolate perianth, and covered with a scaly bract; they form elongated, peduncled, terminal husks. The female flowers, which are twice as long as those of the hura crepitans, have their perianth resting against the ovary, which is surmounted by a long and infundibiliform style, terminated by a stellate stigma; they are solitary and placed near the male flowers. It is from this tree that the Indians draw the milky juice called Assacù by the Brazilians. A man affected with lepra, and who had sought refuge in the solitary regions of the Amazone, took, by the advice of an Indian whom he met there, a considerable quantity of a juice known under the name of Assacù, flowing from the trunk of a tree, which has been described by Willdenow, under the name of hura braziliensis. He was cured; and the president of the province of Para, informed the imperial government of it. Since then, this juice has been very generally used by leprous patients without, however, curing them.
