Li/hophiia Sw. Prod. Veg. Ind. Occ. I4. 1788. Philoxcrzs R. Br. Prodr. Flor. Nov. Hol. 1: 4i6. i8io. Tromsdorfia Mart. Nov. Gen. et Spec. Bras. 2: 40. i826. Hermaphrodite, polygamo-dicecious or dioecious herbs, shrubs or shrubby trees, the latter attaining a height of six meters, with opposite usually petioled leaves, scarious whitish 3-bracted flowers crowded into clusters or spikes in a branching paniculate inflorescence: calyx of five sepals which in 0 and $ flowers are generally almost hidden in long wool which springs from the base of the flower: stamens five; filaments united into a shallow cup at base and bearing staminodia in most species: utricle globular, ovate or urn-shaped with short style and two slender often filiform stigmatic branches. In this synopsis of the genus Ir-esine we have followed the plan stated previously of including such Mexican and Central American.species as were found to be well represented in the herbaria of the United States, so that while we reduce the forms found in the United States to Iresine vermicullaris .(L.) Moq. and Iresine paniculata (L.) Kuntze, with its two varieties, there are here included some eleven other tolerably well defined species from Mexico and Central America, four of which we venture to describe as new, knowing well that a more thorough acquaintance with the Iresines of those regions may show us to be in error. As a matter of interest we would call attention here to the rather surprising fact that from Honduras and Guatemala Iresines are reported which are actually shrubby trees and in one case a small tree six meters in height. * Hermaphrodite.
