Description
Gametophytes
The gametophyte of P. dulcis is cordiform (heart-shaped), becoming elongated as it grows, and sometimes branches. Unicellular marginal hairs are present. Orange and orange-brown unbranched rhizoids usually occur on the distal portion of the gametophyte but may appear elsewhere in larger specimens. Archegonia grow along the midrib of the elongated gametophyte or close to the apical notch (in the top of the "heart" shape). Antheridia appear mixed with them when they occur.[3]
