Systematics of the Trembleya sensu stricto clade of Microlicia (Melastomataceae, Lavoisiereae)

“…There is no evidence of apomixis in M. laniflora ( Soares and Morellato 2018 ). The widely-distributed M. parviflora has been reported as a facultative apomict ( Silva 2001 ) or non-apomictic ( Maia et al 2016 ) and self-compatible ( Silva 2001 ; Maia et al 2016 ). Still, Maia et al (2016) reported reduced speed of pollen tube growth in self-pollination treatments.…”

Polysporangiate anthers in Microlicia D.Don (Melastomataceae Juss.)

“…In Melastomataceae, apomictic species are prevalent in Miconieae (Renner ; Borges ; Goldenberg & Shepherd ; Goldenberg & Varassin ; Santos ; Fracasso & Sazima ; Caetano et al. ), but have also been reported in some Microlicieae, such as Trembleya (Silva ) and Microlicia (Santos et al. ).…”

“…A population of M. fasciculata from another area of "campo rupestre" in Southeastern Brazil is apomictic, with approximately 2% of pollen viability (Santos et al 2012). In Melastomataceae, apomictic species are prevalent in Miconieae (Renner 1989;Borges 1991;Goldenberg & Shepherd 1998;Goldenberg & Varassin 2001;Santos 2003;Fracasso & Sazima 2004;Caetano et al 2013), but have also been reported in some Microlicieae, such as Trembleya (Silva 2000) and Microlicia (Santos et al 2012). These abnormal pollen grains could be related to the breeding system, not to the polysporangiate anther.…”
