They are calciphile and have a pH tolerance of 5.4-8.8.
2.
It is likely a calciphile, as it grows on calcium-rich geological substrates, such as limestone.
3.
This plant is a calciphile, growing only on limestone or rocks that are partly limestone or are derived from limestone.
4.
This is the reason why the area has become an enclave of lime-tolerant ( " calciphile " ) vegetation.
5.
Substrate : " Novisuccinea chittenangoensis " appears to be a calciphile, requiring a substrate either derived from limestone dolomite or rich in calcium carbonate from other sources.
6.
"Saxifraga paniculata " is a calciphile, and hence is found in calcareous habitats : an example of which is in a crevice of a basic rock ( including basalt and volcanic rock conglomerates ).
