| Abstract: | Several populations of Cymbella cistula (Ehr.) Kirchn. were studied. An epiphytic population contained smaller specimens than any reported by recent authors. The size range of members of the epiphytic population included specimens as small as 24 μ long by 11 μ wide. These small specimens could be mistaken for C. cistula var. maculata (Kütz.) V. H., but differ in having isolated puncta, which, may be indistinct, and somewhat coarser striae. |
