Fruits

Pistil(s) compound; 1; 1-pistillate; with carpels united. Fruit anthocarp, or pericarpium; schizocarp; coccarium (Brunia paleacea P. J. Bergius); simple; cypsela (Brunonia australis Sm.), or diclesium (Berzelia abrotanoides Brongn.); without persistent central column; crowned by sepals (commonly by calyx or corolla & androecium); within accessory organ(s), or not within accessory organ(s); within calyx; persistent; 1-seeded (for nut), or more than 1 but less than 10-seeded (for capsule); 1–2-seeded; 2-carpellate (1–3); without sterile carpels; not sulcate; apex not beaked; indehiscent, or dehiscent. Dehiscent regularly; linearly; by ventral sutures; and shedding seeds; without replum. Epicarp durable; sub coriaceous, or thin, or thick; not glabrous (with hairs); hairs dense; hairs red, or yellow; hairs not glandular; without armature, or with armature; with lignified trichomes; without wing(s); without apical respiratory hole. Endocarp present; separating spontaneously from exocarp; thin; not splitting into 1-seeded pyrenes; smooth; without wing; without operculum; without secretory cavities; without mechanism for seedling escape; without grooves; without longitudinal ridges. Funiculus short; short without seed bearing hooks (retinacula); not persisting in fruit after seed shed.

Seeds

Aril present, or absent; a true aril; adnate to hilum; of funicular origin; basal; does not aid in seed explusion from fruit; cupshaped. Seed larger than minute; oblong, or elliptic, or circular, or angular; not bowl shaped; not nutlike; without winglike beak; without caudate appendage(s); at maturity with food reserves; with endosperm; without canavanine. Sarcotesta absent. Testa present; without fleshy or leathery layer over hard layer; surface unsmooth, or smooth; surface with merged raised features; surface wrinkled; without crease or line separating cotyledons from hypocotyl-radicle; without notch along margin where cotyledons from hypocotyl-radicle tip approach each other; without glands; without bristles; without wings; without collar; without operculum; colored; monochrome; crustaceous; not becoming mucilaginous when wetted. Hilum larger than punctate (hilum naked or covered with fleshy cupule). Endosperm copious; fleshy; smooth; without fatty acid containing cyclopropene; without apical lobes; without chlorophyll; without isodiametric faceted surface; without odor.

Embryo differentiated from food reserve; well developed; 1 per seed; partially filling testa (with food reserve); 0.1 times the length of food reserve; at one end of seed not extending into a depression or cup; axile and centric and basal; linear; straight; with cotyledons gradually connected to hypocotyl-radicle; without coleorhiza; without simmondsin; without stomata; not green; with 2 or more cotyledons. Cotyledons 2; tiny; 0.5 times length of embryo; somewhat to significantly wider than hypocotyl-radicle (slightly); with apices entire; with margins separate; equal in size; not punctate dotted. Hypocotyl-radicle moderately developed; coiled; not thickened.

Distribution

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
