- n. Any of various submerged aquatic algae of the genus Chara that are frequently encrusted with calcium carbonate deposits and have nodes with whorled, filamentlike branches.
Century Dictionary and Cyclopedia
- n. A plant of the genus Chara: so called from the calcareous deposits which frequently occur on the stems.
- n. Sometimes, the stone-parsley, Sison Amomum.
- n. Any of various complex algae of the family Characeae, known for being branched and having enclosed egg cells.
GNU Webster's 1913
- n. (Bot.) Any plant of the genus Chara; -- so called because they are often incrusted with carbonate of lime. See chara.
- n. any of various submerged aquatic algae of the genus Chara having nodes with whorled filamentlike branches; usually encrusted with calcium carbonate deposits
“With regard to suitable plants for comparatively deep water in ponds or lakes, lakewort and stonewort grow on the bottom, and do not, as a rule, attain any considerable height.”
“Predation from visually hunting fish is thus likely to be much more intense in the stonewort habitat than in the reed, due to higher densities of perch in the novel habitat”
“Linear regression between endurance and speed for individuals from the reed and the stonewort.”
“These size classes were above or below .95 cm for the reed ecotypes, and above or bellow .75 cm for the stonewort ecotype.”
“It is important to note that there is evidence that, at least in Lake Krankesjön, these phenotypic changes occurred after colonization of the stonewort, since when isopods were initially sampled shortly after the stonewort started to expand (in 1987) they were phenotypically similar to reed individuals”
“In a recent study, we have showed that in these lakes, stonewort ecotype isopods were smaller in body size and had lighter body pigmentation”
“Indeed, although our data on exploratory behaviors comes from only one lake, and thus precludes generalization, we have also found in a previous study that stonewort individuals from both lakes had a lower propensity to engage mating, which also independently suggests a tendency to avoid exposure”
“The latter mechanism may be selected for in the reed habitat, as reed isopods are faster at escaping and have higher endurance than stonewort isopods.”
“Selection for lower foraging activity and lower speed in turn might presumably result from the fact that isopods in the stonewort cannot escape from fish predators by swimming away, but have to rely on combinations of cryptic behavior, morphology and pigmentation to avoid predation.”
“They are more stream-profiled and have higher escape speeds than isopods in the newly colonized stonewort habitat, which has higher density of fish predators.”

I have in mind the worts associated with a green thumb rather than a green beer - but as you can see by the name, I'll accept anything you have to offer.
