Information

Small shrubs or shrubby perennials, or annuals, with entire, alternate leaves. Flowers in spike-like, axillary, bracteate racemes, each bract subtending a sessile partial inflorescence consisting of a central fertile flower and two highly modified, sterile, unibracteolate lateral flowers, which are small and blunt at anthesis but gradually accrescent in fruit to form a broad, membranous wing with prominent anastomosing veins. Tepals 5, the outer pair firm and nervose, the inner 3 more delicate and hyaline. Stamens 5, shortly fused at the base; pseudostaminodes absent. Ovary 1-ovulate. Style short and thick, shortly bilobed. Fruit a hard, indehiscent ± compressed nutlet with a thick circumferential rim, enclosed by the persistent perianth and falling together with the sterile flowers and bracteoles.
