Thymelaeaceae

Spurge flax Thymelaea passerina, photographed by Václav Dvořák.


Belongs within: Malvales.
Contains: Pimelea.

The Thymelaeaceae is a cosmopolitan family containing the daphnes and related species, most of which are shrubs or small trees. Many species of the family have fibrous bark that is used to make high quality paper. Species of Daphne are cultivated for their fragrant flowers.

Characters (from Wang et al.): Shrubs or small trees, rarely herbs, evergreen or deciduous. Bark tough and fibrous. Leaves opposite or alternate, rarely some ternate, estipulate; blade simple, entire, pinnately veined, articulate at base. Plants mostly bisexual, sometimes dioecious. Inflorescences terminal or subterminal, less often axillary, sometimes on brachyblasts, sessile or pedunculate, basically racemose, sometimes capitate, spicate, umbelliform, or fascicled. Flowers usually actinomorphic, bisexual or unisexual (plants then mostly dioecious), bracteate (sometimes bracts forming an involucre) or ebracteate, sessile or pedicellate. Calyx tubular, campanulate, or infundibuliform, usually corollalike, 4- or 5(or 6)-merous, mostly caducous, sometimes circumscissile, or persistent; lobes imbricate. Petals absent or represented by 4-12 scales, inserted at or near throat of calyx tube (Aquilaria). Stamens 2 to many, usually as many as calyx lobes and opposite them or twice as many. Hypognous disk usually present at base of ovary, scalelike, annular or cup-shaped, sometimes absent. Ovary superior, 1- or 2-loculed, sessile or shortly stipitate; ovules solitary in each locule, pendulous, anatropous; style filiform, caducous, sometimes very short or obscure, terminal or eccentric; stigma capitate, globose, subglobose, subclavate, or pyramidal, sometimes papilose. Fruit mostly indehiscent, dry or fleshy, sometimes a loculicidal capsule (Aquilaria). Seeds with or without endosperm, embryo straight.
