“…Secretory spaces with digitiform elongated epithelial cells intersecting the lumen and forming trabeculae, previously observed in P. pubescens by Rodrigues & Machado (2012), were found in all three species studied here. The trabeculae in the lumen of these secretory spaces probably play a functional role as a framework to support secretion inside the wide lumen of these glands, since secretion products accumulate within the interstices.…”

“…Secretory spaces have already been documented in some members of Dipteryx, Pterodon and Taralea (see Rodrigues & Machado 2004;Paiva et al 2008;Rodrigues & Machado 2012;Leite et al 2014), but are absent in Monoteryx (FH Palermo unpubl. res.…”

“…Total lipids and terpenes were abundantly stained by the histochemical tests in the morphotype I, mainly in the head cells. In fact, the observation of several plastids lacking thylakoids in the head cells is associated with the production of oils (Fahn 1979;Rodrigues & Machado 2012); in addition, the presence of tubular inclusions in these plastids is common reported in cells secreting monoterpenes (Turner et al 1999). In general way, lipids are released from the secretory cells via ecrine (Evert 2006), cross the cell wall driven by the mechanical pressure exercised by the protoplast (Paiva 2016) and accumulate in the subcuticular space; oil material can cross the cuticle and reach the outer side of the cells without requiring rupture of pore formation in the cuticle.…”
