Auxin regulation of axial growth in bryophyte sporophytes: its potential significance for the evolution of early land plants

For the coming checklist of hornworts and liverworts (Söderström et al., in press) a few validations, transfers and synonymizations in the family Lejeuneaceae are still required.

Plagiochilaceae is here circumscribed to include 10 genera, Acrochila, Chiastocaulon, Dinckleria, Pedinophyllopsis, Pedinophyllum, Plagiochila, Plagiochilidium, Plagiochilion, Pseudolophocolea and Xenochila. For the forthcoming world checklist of hornworts and liverworts we here summarize the current knowledge and identify the sections of Plagiochila that are currently recognized by morphological and molecular studies. Plagiochila is provisionally divided into 28 sections based on recent morphological and molecular studies. Plagiochila ecuadorica and Plagiochila sciophila subsp. ciliigera are new combinations, Plagiochila umbrosioides is a nomen novum.

Stem Structure

The segregate of Myriocoleopsis was firstly proposed by Schiffner (1944: 234) based on some remarkable characters, such as dimorphic stems, long male spikes, erect leafy axes arising from a creeping stolon and reduced lobules (Gradstein & Vital 1975; Reiner-Drehwald & Gradstein 1995). Hitherto a total of three species are recognized in this genus: Myriocoleopsis fluviatilis (Stephani 1895: 248) Reiner & Gradstein (1997: 639) known from Argentina, Brazil and Ecuador (Reiner-Drehwald & Gradstein 1997; Gradstein & da Costa 2003), M. gymnocolea Spruce (1884: 296) Reiner & Gradstein (1997: 640) known only from Brazil (Reiner-Drehwald & Gradstein 1997) and M. vuquangensis (Pócs & Ninh 2005: 156) Pócs (2010: 124) known only from Vietnam (Pócs 2010). Myriocoleopsis shares substantial resemblance with Cololejeunea (Spruce 1884: 291) Stephani (1891: 208) (particular subgen. Protocolea Schuster (1963: 171)) in the stem structure, absence of underleaves, lobular form, leaf margin, oil bodies and sporophytes (Gradstein & Vital 1975; Schuster 1980; Reiner-Drehwald & Gradstein 1995). Although the rigid stem and large size of Myriocoleopsis was also found in some rheophytic taxa of Cololejeunea such as subgen. Chlorolejeunea Benedix (1953: 81), it had been interpreted as adaption to similar habitats (Reiner-Drehwald & Gradstein 1995).
