Here in Florida there are nettles specifically associated with deeply
shaded limestone outcrops. I think the genus is Laportea but not the species
canadensis. The best way to find them is to get all hot and sweaty then climb
up overgrown rocky bluffs with bare arms and legs. They go well with
mosquitos, spider webs, and water moccasins.
I have seen lots of nettlish looking lithophytes, probably Pilea, growing
on moist vertical travertine in many different places in southeast Asia.
I've never heard it called petaloid travertine before, but it is as good a
name as any for the drapery like forms.
I believe that all the huge fast growing spleleothems that occur outside of
caves throughout the moist tropics are due to preferential deposition by
some sort of blue green algae. Such porous rock serves as a fine substrate
for lithophytes.
