The families of flowering plants.
Habit and leaf form. Trees.Leaves large; alternate; simple. Lamina entire; ovate. Leaves exstipulate. Lamina margins entire.
Reproductive type, pollination. Plants hermaphrodite, or monoecious, or dioecious, or polygamomonoecious (?).
Inflorescence, floral, fruit and seed morphology. Flowers aggregated in ‘inflorescences’; in racemes. The ultimate inflorescence unit racemose. Inflorescences axillary. Flowers one to two bracteolate.
Perianthwith distinct calyx and corolla, or sepaline (?). Calyx 5; 1 whorled; polysepalous; much imbricate. Corolla unknown.
Gynoecium5 carpelled. The pistil 5 celled. Gynoecium syncarpous; synovarious, or synstylovarious, or eu-syncarpous; superior. Ovary5 locular. Ovules (or at least, the seeds) non-arillate.
Fruitfleshy; dehiscent, or indehiscent (?); a capsule (tardily dehiscent), or a berry (?); 1(–10) seeded (?). Seeds non-endospermic; large. Embryo well differentiated. Cotyledons 2 (fleshy, contorted).
Geography, cytology. Paleotropical. Tropical. Western Malaysia.
Taxonomy.Subclass Dicotyledonae (two poorly known genera, whose affinities are uncertain); Crassinucelli, or Tenuinucelli (?). Dahlgren’s Superorder Primuliflorae; Ebenales. Cronquist’s Subclass Dilleniidae; Ebenales. APG 3 core angiosperms; core eudicot; Superorder Asteranae; Order Ericales (as a synonym of Sapotaceae?).
Species 2. Genera 2; only genera, Boerlagella, Dubardella.
General remarks. Inseparable in terms of this description from Rosaceae and Simaroubaceae. Gunn et al. (1992) refer it tentatively to Sapotaceae, from which it seems to differ in the racemose inflorescence and (?)lack of latex.
