THE TORCHWOODS GENUS AMYMS LINN^US [iMYRIS comprises about 15 species of unarmed trees or shrubs of tropi- cal America. They abound in fragrant resinous substances, and have been used as aromatics and stimulants. They have either alternate or opposite, usually compound leaves which are conspicuously glandular-punctate. The flowers are perfect or polyga- mous, white, and borne in terminal or axillary panicles. The calyx is umshaped and 4-lobed; the 4 petals are imbricated; stamens 8, inserted on the disk, their filaments exsferted; anthers ovate, introrse and opening lengthwise; ovary i-celled, rudimentary or sterile in the staminate flowers; style terminal, short or none; stigma capitate; ovules 2, suspended from the top of the cavity. The fruit is an aro- matic, ovoid or obovoid drupe with a papery stone which is one-seeded; seed pen- dulous, without endosperm; the embryo is small. The name is Greek in allusion to their aromatic or balsamic properties; the type species is A. elemifera. In addition to the arborescent species a shrub, Amyris parvijoUa A. Gray, occurs on our Mexican border. Leaflets shining beneath;
