New Charophyte (Stonewort) and Bryophyte records
older stems much smaller and papillata-like. Antheridia,
oogonia and ripe oospores present 17 Sept 1999. Found
by Shirley & Charles Watson.
[N.B. when grown on indoors in tap water (KJA) this
material grew vigorously but lost its long spines, and the new
shoots took on the morphology of classical Chara contraria, with
knob-like spine cells arising only from the ridges. Thus, as in the
case of the C. vulgaris s.s. 'varieties' var. contraria and var.
hispidula cannot be separate genetically defined varieties and
are simply environmentally induced ecomorphs of the same
taxon.]
