Warming states that the stomata of true, succulent, littoral halophytic herbs, in cases so far investigated, are not sunken (1909: 221).
It is possible, however, that the absence of sunken stomata, and the occurrence of some other halophytic features, are related merely to the succulent habit and not to halophytism, for succulent species often occur on non-saline soils.
