There are many factors that can determine the geographic distribution
of a plant, but the most important one is SOIL type (rainfall,
elevation, climate, and light are also important factors).
From personal experience, I know the panhandle has very sandy, acidic
soil, while the lower part of the state has very calcareous, basic
soil. This is because of the extensive limestone deposits found
there. The Gulf coast between far eastern Louisiana and the Florida
panhandle all have similar soils, and also supports large populations
of cp. I suppose one could call this region the "cp crescent",
because of the crescent shape of the coastline there (Wow! A new cp
term! You heard it here, first!) ;-)
Texas has mostly calcareous soils along the Gulf coast, which probably
limits the number of cp found there. Southeast Texas, home of S.
alata, various Droseras and Pings, has sandy soil.
