Fig. 2From: Chloroplast genomes of five Oedogonium species: genome structure, phylogenetic analysis and adaptive evolutionPhotos of habitat and light microscopy of Oe. capilliforme and two undefined species. A-E Oe. capilliforme. A Unbranched female filament with oogonium single or 2-continues, oogonium with superior pore. B Oogonium with median pore. C Antheridium in 2–7 in a series, with sperms 2, division horizontal. D Apiculate terminal cell. E Elongated basal cell. F Oe. sp. (strain FACHB-3311), showing the unbranched filament with young oogonium. G Oe. sp. (strain FACHB-3313), unbranched filament with rhizoid (4% formaldehyde fixed sample).
