Trophis involucrata W.C. Burger, an understory tree in the Moraceae. Note the strongly looping secondary veins and the net-like pattern of tertiary veins. Un árbol del subdosel. Note que las venas grandes se unen cerca de los margenes, y que las venas pequeñas tienen un patron reticulado.

Description: A large and important tropical family, with simple alternate leaves, stipules, and often with white latex or colored sap. One genus here (Dorstenia) is an herb; the rest are trees or strangling hemiepiphytes. Genera in the tribe Moraeae (Ficus, Brosimum, and Naucleopsis) have stipule scars that encircle the twig (note that this family is undergoing revision, though, and the eventual assignment of these genera may put them in different tribes; N. Zamora, pers. comm). Almost all Moraceae have pale veins which stick out from the underside of the leaf (prominulous). Ficus is the largest genus in this region, and it can be easily identified from the unusual form of its fruit (i.e., a fig, technically known as a syconium). The flower heads of Dorstenia look like figs cut open and spread flat.

Economic uses: A number of Ficus species are cultivated for their fruit, mainly in the Old World. Artocarpus altilis, the breadfruit, is a Polynesian native that is widely grown in the Neotropics. In the temperate zone, mulberries (Morus species) are commonly eaten. Castilla elastica was investigated for its potential as a source of rubber during World War II, but it was not found effective.


Descripción: Una familia grande y con gran importancia en las zonas tropicales, con hojas simples y alternas, con estípulas, y muchas veces con savia opaca y blanca o clara y de colores. Un género en La Selva (Dorstenia) es una hierba; los demás son árboles o hemiepífitas (matapalos). Géneros de la tribu Moraeae (Ficus, Brosimum, y Naucleopsis) tienen cicatrices de las estípulas que rodean las ramitas (es de notar que se está revisando esta familia, y la posición de estos géneros puede cambiarse; N. Zamora, comm. pers). Casi todas las Moraceas tienen las venas pálidas y promínulas (es decir, que sobresalen del envés de la hoja). Ficus es el genero más grande en esta área, y se puede identificar muy fácilmente por sus frutos señeros (higos, o técnicamente siconos). Las flores de Dorstenia parecen higos disecados.

Usos económicos: Algunas especies de Ficus se cultiva por sus frutas; la mayoría son del viejo mundo. Artocarpus altilis, el frutapan, es nativo a Polinesia pero se cultiva ampliamente en el nuevo mundo. In las zonas templadas, se consumen los frutos dulces de varias especies de Morus. Durante la segunda Guerra Mundial, se investigó sin éxito el uso de la savia de Castilla elastica como un fuente de hule.


Gen./spp. at La Selva: 12/33: Artocarpus (1), Brosimum (3), Castilla (1), Clarisia (1), Dorstenia (2), Ficus (17), Maquira (1), Naucleopsis (1), Perebea (1), Pseudolmedia (1), Sorocea (1), Trophis (2).
