rift lake plants too
Ted:
I'm back. I'm still at home with a powerbook and external modem.
I managed to get into my office computer files and get some more
data. This is world literature data, records of pH levels in lakes
where plants were found growing. How happy they were is another
question. I chose an arbitrary cut-off of pH 9.5 and tried to ignore
plants which would not make good aquarium specimens but I still
came up with a good list of plants recorded as growing at this high
pH or better
