Basswood Family

Description: Tiliaceae are mainly canopy trees, especially prevalent in second-growth forest. Most of them have yellow flowers with many free stamens, and each genus has a distinctive and often bizarre-looking fruit (e.g. the “sea urchin” fruit of Apeiba membranacea). Vegetatively, Tiliaceae are hard to distinguish from other Malvalean families. Several leaf characters are important for identification. The genera here have leaves that are always simple and unlobed, and usually serrate. Most of them have a contrasting leaf underside (whitish or brownish).
Economic uses: In the temperate zone, the linden or plane tree (Tilia americana) is frequently planted as a shade tree.
Descripción: La mayoría de las Tiliaceas son árboles de dosel, muy comunes en bosque secundario. Muchas tienen flores amarillas con muchos estambres libres, y cada género tiene un fruto distintivo y usualmente de forma particular (p. ej. el fruto de Apeiba membranacea, que parece un erizo del mar). Por lo general, es difícil distinguir las Tiliaceas de otras familias de Malvales. Varias características de la hoja son útiles para identificación: los géneros de esta área tienen hojas simples, sin lóbulos, y usualmente con la margen serrada. Muchas tienen un contraste entre el haz y el envés (con el envés blancuzco o castaño).
Usos económicos: En las zonas templadas, se siembran muchos árboles de Tilia americana como sombrio.
Genera/species at La Selva: 7/7 (all trees/ todos árboles): Apeiba, Goethalsia, Heliocarpus, Luehea, Mortoniodendron, Triumfetta, Trichospermum.
FIELD MARKS – All have traits found in the large Malvaceae sensu lato, including alternate leaves, 3 main veins originating from base of leaf, serrate leaf margins, stellate hairs, mucilage, bark that peels in long strings, monadelphus stamens
Genera are best determined by their fruits.
Apeiba membranacea – fruits resemble a sea urchin with a dense coating of short spines.
Goethalsia meiantha
Luehea seemannii
Trichospermum – fruit is a capsule containing flattened seeds with hairs.
