| Shrubs or trees. Youngest branchlets compressed, older branches terete; base of the lateral twigs often provided with small distichous ‘bracts’ (ramenta) sometimes also occurring between the leaves. Leaves simple, alternate (distichous), entire, involute in bud, the margins leaving a more or less permanent trace as 2 longitudinal lines on the upper leaf surface (‘areolate’). Stipules mostly entirely connate, rarely bifid, intrapetiolar, often bicarinate, sometimes emarginate or 2-toothed at the apex, long-persistent or early caducous, inserted ± semi-amplexicaulous and leaving a distinct, mostly oblique scar. Flowers axillary, solitary or in clusters, often dimorphous, or even 3—4-morphous, 5-merous, actinomorphic, bisexual. Pedicels more or less... |

All aspects, also of auxiliary disciplines point to affinity with Myrtaceae but warrant separate family status. The conviction is that only one family is concerned, not two, or even three, as Knuth proposed. The subdivision of Lecythidaceae appears to meet with great difficulty. It does not seem to be possible to divide the family in tribes which would be restricted to the New and Old Worlds respectively, affinities running transoceanic. In the present revision of the genus Barringtonia 39 species are distinguished, 3 of which have one or a few new subspecies, varieties, or forms; three species are newly described. A survey is given of the... |
