Dicliny in Bouteloua (Poaceae: Chloridoideae): Implications for the Evolution of Dioecy
, 2007 The New World grass genus Bouteloua (Chloridoideae: Cynodonteae) comprises 57 species, 13 of which produce unisexual spikelets and hence are diclinous. Andromonoecy, gynodioecy, monoecy, trimonoecy, and dioecy all occur in the genus, and ten species are ...

Exceptions from dioecy and sex lability in genus Salix
, 2014 Bisexualism (and its derivatives) is a rare exception in species which already acquired the dioecious breeding system. Although it occurs in some tree species, it is still rather uncommon, except for willows, in which bisexualism occurs in at least 18 ...
