Pollen fertility is estimated by squashing mature anthers (before dehiscence) in a drop of 0.5% cotton blue in lactophenol.

Thus, so far as reproductive isolation is concerned, some ecotypes behave essentially as separate species (see Sect. 2.1). This is an enigmatic situation from the cytogenetic and breeding standpoints.
