“…While many bryophyte placentas have multiple layers of transfer cells (Browning and Gunning 1979a;Alfayate et al 2000), wall ingrowths occur only in the outermost foot layer and adjacent gametophyte cells in leptosporangiate ferns (Gunning and Pate 1969a;Khatoon 1986;Duckett and Ligrone 2003). Absence of ingrowths in gametophyte cells not interdigitated with peripheral foot transfer cells corroborates prior studies (Duckett and Ligrone 2003) and implies that transfer cell differentiation may be related to placental interdigitation.…”

“…A placental space containing crushed cells between generations observed in certain lycophytes and bryophytes (Alfayate et al 2000;Frey et al 2001;Hilger et al 2002) is absent in C. richardii. While many bryophyte placentas have multiple layers of transfer cells (Browning and Gunning 1979a;Alfayate et al 2000), wall ingrowths occur only in the outermost foot layer and adjacent gametophyte cells in leptosporangiate ferns (Gunning and Pate 1969a;Khatoon 1986;Duckett and Ligrone 2003).…”

“…Similarly, while most moss sporophytes contain a special opening structure (the annulus) enabling controlled dehiscence and regulated release of spores, most liverwort and all hornwort sporophytes open along two or more preformed slits ( Crandall-Stotler and Stotler, 2008 ; Renzaglia et al., 2009 ). Additionally, while moss, liverwort and hornwort sporophytes are all nurtured by the gametophyte, nutrient transfer cells occur only in the gametophyte of hornworts while they are present in both the gametophyte and sporophyte tissues of several mosses and liverworts ( Alfayate et al., 2000 ; Buck and Goffinet, 2000 ; Carafa et al., 2003 ; Crandall-Stotler and Stotler, 2008 ; Villarreal and Renzaglia, 2015 ). Finally, unlike mosses and liverworts, hornworts lack both water- and nutrient-conducting cells ( Ligrone et al., 2000 ), with the evolutionary, physiological, and developmental aspects of this still not understood.…”
