PLACONEIS Mereschkowsky
Bacillariophyceae
Beih. Bot. Centralbl. 15: 3. 1903. (G)
comprises Placoneis subsalsa n.sp. and 8 previously published species
T. See Placoneis gastrum (Ehrenberg) Mereschkowsky (See Pinnularia gastrum Ehrenberg 1843)
[Round et al. (Diatoms, 1990) cite P. gastrum as type on p. 484, but P. exigua on p. 697; Fourtanier & Kociolek (Diat. Res. 14: 104. 1999) also cite P. exigua and thus misinterpret Cox]
