Caracteriza-se por ser uma espécie polimórfica que exibe diferenças quanto à cor e nível de cerosidade das folhas, ao formato, tamanho e cor dos bulbos, e à reação ao Apart from the long arms of, the longest chromosome of the complement which are, unpaired (Figure 19), crossing over appears to be non-, localized. We therefore argue that theoretical and empirical work aimed at understanding ecological factors that condition “escape‐and‐radiate” dynamics will allow for more nuanced tests of the hypothesis in the future.
