Heterosiphonia muelleri   (Sonder) De Toni,  1903 (Algae)
Organism information awaits expert curation
Class: Florideophyceae

Color: When fresh dark red to rose red, older ones brownish red.

Plants erect, forming dense bushy growth when vigorous and healthy. Base creeping rhizome-like, perennial, thick, cartilaginous with short spine-like branchlets from the surface of rhizome. Frond, shaggy, erect with feathery stems- the primary branches. Primary branch, 10 cm or more in height, 1-1.5 mm thick, dark red with somewhat hairy structures, irregularly divided or dichotomous. Branches widely spreading, annual. Segments in main stem with 10 pericentral cells. Free ends of branch system, alternating in 2 rows on both sides of the main stem. Pinnules formed likewise, with 2 or 3 short spine-like branchlets. Cells in the older thallus 30-50 µ broad and 100 µ long, cylindrical. Substance, main stem, rigid; branches soft, flaccid.

During unfavorable seasons and in older plants, the lower portions of the stem are devoid of pinnules, when they present quite a contrasting appearance to the vigorously growing feathery and soft plants in bushy forms.
