| The pericarp development of Serjania communis Camb. and Urvillea ulmacea Kunth was described to expand the structural knowledge of Sapindaceae fruit. Ovaries and fruits were analyzed with usual techniques in plant anatomy. Ovary is structurally similar and the occurrence of glandular and non-glandular trichomes varies between species. In S. communis, the samaroid schizocarp has proximal wings and distal cavities; in U. ulmacea, the fruit presents septicidal and septifragal passive dehiscence and each seed chamber presents a dorsal wing. The unistratified exocarp has long pluricellular, uniseriate and sparse trichomes in U. ulmacea. The mesocarp is spongy, parenchymatous and in S. communis it presents three distinguished regions. Dorsal, lateral and ventral... |
