mean ? standard deviation) as those from cross-pollinations (24.7 ? 14.0). Germination was slightly lower for seeds produced from self-pollinations (62.3 ? 36.1%) as compared with seeds from cross-pollinations (77.7 ? 22.9%). Self- and cross-pollinations resulted in fruits with significantly more seeds than open-pollinations (13.4 ? 7.3). Unlike other long-styled species of Zephyranthes, Z. atamasco is fully self-compatible, and seeds produced from self-pollinations are similar in number and viability to seeds produced from cross-pollinations. Nevertheless, autogamous seed production is very low, presumably because the long styles project the receptive stigmatic surfaces well beyond the dehiscing anthers.
