1889 Amer. Naturalist 23 507 The over-growth of Protozoan or Protistan forms probably gave rise, through a series of segmentations, directly to such types as Volvox.

1959 Ann. N.Y. Acad. Sci. 77 51 Microbiology has domesticated thousands of protistan species, trapping them out of microcosmic jungles that burgeon throughout the biosphere.

1989 Jrnl. Hist. Biol. 22 298 The adoption of a protistan Kingdom can be attributed largely to its appearance in three influential texts.
