Electronic Flora of South Australia Family Fact Sheet

FAMILY CHORISTOCARPACEAE Kjellman

Phylum Phaeophyta – Order Sphacelariales

Thallus tufted, erect, filamentous, branched, uniseriate throughout, with large apical cells and without division of the subapical cell; subapical cells not elongating significantly. Cells with numerous phaeoplasts without pyrenoids; hairs absent.

Reproduction: Reproduction by pedicellate propagula and by unilocular or plurilocular reproductive organs, the latter ovoid or a more or less square disc of sporangia.

Taxonomic notes: This family of Kjellman (1897, p. 190), with 2 or 3 genera, is usually placed in the Sphacelariales (Henry 1985) though this is considered unlikely by Prud'homme van Reine (1982, p. 28) who points out that the members lack subdivision of primary segments of the apical cell and do not show wall blackening with Eau de Javelle.
