50 - ENCOELIACEAE 
In Streblonema Софи E. S. Barton (Jour. Bot. 34: 194. 1806), 
growing on Codium adhaerens at the Саре of Good Hope, the 
scarcely exserted vegetative branches are only 60-90 и long and 
8-10 и broad. 
Ectocarpus simplex Crouan, as represented in Desmaz. PI. 
Crypt. Fr. no. 1806, and Ectocarpus virescens Thuret, both of which 
occur on species of Codium, are so different from Streblonema 
Сокет that a detailed comparison is unnecessary. Both of these, 
however, agree with S. Cokeri in having rhizoids that may be 
more or less ‘‘endophytic.”

1. A tuft of filaments on apex of peripheral utricle of Codium. 
2. Portion of a tuft showing basal branching, rhizoidal or omar я filaments, etc. 
3. A filament, showing form of cells, two m microsporangia, 
4. An apical microsporangium, with a lateral supposed megasporangium below. 
5. Portion of filament showing chromatophores and two lateral sporangia, of which 
the one on the ipis is supposed to be a microsporangium and that on the 
left a megaspora 
6. А portion of a Came, a ae form of cells and chromatophores. 
7. А supposed megasporangium.

meager to justify an attempt at determination or description.
