See the following description from Wikipedia:

The Phyllanthaceae are nearly all trees, shrubs, or herbs. A few are climbers, or succulents, and one species, Phyllanthus fluitans, is aquatic. Unlike many of the Euphorbiaceae, none have latex, and only a very few produce a resinous exudate. Any hairs, if present, are almost always simple. Rarely are they branched or scale-like. Thorns and other armament are rare.
