Marchantia berteroana

Family: Marchantiaceae

Marchantia berteroana has a branching and lobed thallus with undulate margins. The dorsal epidermis has conspicuous air pores each with a hydrophobic cuticular ledge protecting against water loss; each pore leads into large sub-epidermal air chamber. Asexual propagules (gemmae) are formed in large gemmae cups with toothed margins . Female and male gametangia are borne on erect branches of the thallus called archegoniophores (female) and antheriodiophores (male). 

Widespread in New Zealand on moist soil.
