ter Hincks.) Noted from Nutting's 
LAF@IDA. 
This family has been variously modified of late and by some replaced 
entirely. In the present synopsis I have chosen to follow in general the 
classification of Hincks, though recognizing its doubtful reliability in x 
respects. 
Lafca Lamx. 
Stems simple or fascicled, attached by filiform hydrorhiza. Hydrothec® 
tubular, with or without operculum. Gonangia oblong, often io 
encrusting masses about the stem.
