Perennial to tree; hairs stellate (or scale-like, peltate)
Leaves cauline, alternate, simple or palmately compound, evergreen, petioled; stipules generally deciduous
Inflorescence: generally complex clusters, cymes, or flowers solitary (in axils, opposite leaves, or on a spur branch); whorl of bracts often subtends calyx (especially if petals 0)
Flower bisexual, radial; sepals 5, generally fused at base; petals 0 or 5, clawed, sometimes fused to filament tube; stamens 5 (sometimes alternate 5 staminodes), filaments fused below into tube; ovary superior, sometimes on a stalk that may be fused to filament tube, chambers generally 5, style 1
Fruit: capsule
Genera in family: 60 genera, 700 species: generally tropical, subtropical; some cultivated for ornamental (Fremontodendron ) or for drugs and food (Cola ; Theobroma , chocolate)

Inflorescence: flowers generally solitary, opposite a leaf or on a spur; flower subtended by generally 3 sepal-like bracts
Flower > 25 mm wide, showy; sepals spreading, widely ovate to ± round, upper surfaces pitted between raised, hard, fused basal margins, tip awned or not; petals 0; filaments thick, fleshy, tube surrounding and ± = ovary, < style; ovary (and fruit) sessile

See the CNPS Inventory for information about endangerment and rarity.| YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps). |
