Macrocystis pyrifera GiantKelp. - Found in Baja all the way upthrough BC. -Maincanopy forming algae in more protected environments |
|

Chondracanthus exasperatus TurkishTowel - Low intertidal, exposed rocky headlandsto sheltered localities. - Thalli 20-70 cm tall, fleshy or crisp,yellowish- green to brownish-red in sheltered habitats, brick red (north ofPoint Conception and in Baja California) or pink (south of Point Conception tothe Mexican border) on exposed coasts, consisting of one to several blades froma discoid holdfast up to 1 cm broad; blades 6- 20 cm wide, 0.2-3 mm thick,simple or forked, lanceolate tolong-elliptical and tapered to a blunt or acuminate tip, the margins entire ordentate or sometimes bearing bladelets; stipitate, the stipe usually 2-3 cm long bearinglateral bladelets andexpanding to a short, fleshy and flattened cuneate base; surface and margins of blades,except the base covered with closely to widely spaced, spinoseoutgrowths; cortex 5-7 cell layers thick; medullary cells variable in size andshape, 1.5-24 mm in width. Spermatangial sorisuperficial, indefinite on slender, elongate papillae with thin attenuatingtips. Gonimoblastforming a compact group of cells around the auxiliary cell with cortical andmedullary cells producing short-celled filaments circling the gonimoblasts;later in development, a well-defined envelope composed of short and densefilaments forms to surround the carposporophyte. Cystocarps0.8-1.5 mm in diameter, hemispherical, frequently fusing to form a single,compound cystocarp,located in papillae that are sometimes ornamented with spines, 1-3 per papilla.Carpospores subspherical,12-18 µm in diameter, at maturity released through an ostiole. Tetrasporangial sori0.2-1 mm in diameter, developing at the junction between the emerging papillaand the blade. Tetrasporangia34-42 µm in diameter, transforming from primary cortical filaments in branchedchains 9-12 cells long. As the papilla grows, the new primary corticalfilaments are transformed into tetrasporangialchains, sometimes forming 2-3 hemiisphericalrings of sori onthe nipple-like papillae. At maturity tetraspores are released through cracks in thecortical wall, leaving behind an empty cavity. |
