Pollen morphology in Brazilian species of Gloxiniinae (Gesneriaceae): variation in apertures and pattern of ornamentation
Sign Up to like & getrecommendations! Published in 2018 at "Plant Systematics and Evolution"
DOI: 10.1007/s00606-018-1526-z
Abstract: Gloxiniinae comprises herbs and subshrubs usually growing on rocky outcrops, rocky fields or gallery forests. For Gesneriaceae in some cases variations in pollen morphology allow the differentiation of genera and species. We studied the pollen… read more here.
