SOUARI NUT, OR BUTTERNUT.--This nut, like the last, is a native of British Guiana, and is the fruit of the _Caryocar nuciferum_, a noble tree, growing a hundred feet high, having large, broad, trifoliate leaves, resembling those of our common horse-chestnut, but not quite as broad. The flowers are very large, and, with the tube, fully a foot long, of a deep purple on the outside, and yellow within. They are composed of five thick, fleshy petals, and as showy as some of our best and brightest-colored magnolias. The flowers are produced in terminal clusters or corymbs, succeeded by a large, round, four-celled fleshy fruit five to six inches in diameter; but as some of the embryo nuts usually fail to grow, it changes the form of the fruit as it enlarges towards maturity, and only one or two of the nuts mature and ripen, very much as frequently occurs in both the sweet and horse-chestnuts. The nuts are affixed to a central axis, and are of a rounded, subreniform shape, and even flattened to an almost sharp edge on one side, and broadly truncate at the scar (hilum) where they are attached to the pericarp or central axis. The shell is of a deep brown color, embossed, as it were, with smooth tubercles. They are from two to two and a half inches or more in their broadest diameter, as shown in Fig. 106. The kernel or meat is pure white, soft, rich and oily, with a pleasant flavor. This nut is a rarity in our markets, and Mr. H. R. Davy of New York, to whom I am indebted for a specimen, as well as other rare kinds, assures me that in his forty-five years' experience as a dealer in foreign fruits and nuts, he has never known of but one lot, and that one consisted of about one-half bushel, brought into his store by a sailor, who only knew their common South American name. These nuts are more frequently seen in European seaports than in those of this country. SOUTH SEA CHESTNUT.--See Tahitian chestnut. TAHITIAN CHESTNUT.--The seeds of a tree known in the South Sea islands by the native name of Toi, but to botanists as _Inocarpus edulis_. It belongs to the bean family (_Leguminosæ_). The tree grows sixty to eighty feet high, and when young the stems are fluted like a Grecian column, but as they increase with age the projections extend outward, until they form a kind of buttress all around the lower part, gradually decreasing upward. This so-called chestnut tree has yellow flowers, succeeded by fibrous pods containing one large seed or nut, which, when roasted or boiled, resembles the chestnut in taste. The nuts have a different local name in almost every one of the Pacific islands where it is at all abundant. TAVOLA NUT.--See Myrobalan nut.
