HooKEB & Thomsok i^l. Ind., i. 154), according to which the mace is of mixed nature—both arillode and true aril—is the only one that comes near the truth. It is an aril produced by both hilum and micropyle. ' The female inflorescences of M. fragrcms a,ve rather comparable to cymes. In the 3-flowered ones, for instance, we may observe this. One flower is central, older, and on a longer pedicel than the others. Where its pedicel separates from the common peduncle of the inflorescence there are two bracts, situated near one another and ,on the same side; each of these has a younger pedicellate flower in its axil. 2 Attbi., Guian., 904, t. 345. — A.
