Monographs Details: Scytonema javanicum var. distortum N.L.Gardner
Authority: Gardner, Nathaniel L. 1927. New Myxophyceae from Porto Rico. Mem. New York Bot. Gard. 7: 1-144. pl. 1-23.
Description:Species Description - Filaments 13.8-15 µ diam., 200-300 µ long, branching frequent, mostly by bowing out of the trichome and later breaking apart, much contorted; heterocysts numerous, much compressed.

Distribution and Ecology - Growing on trees north of Mayagiiez, no. 1000, type.

Discussion:The variety is to be distinguished from the species by the method of branching, the trichomes pushing out in the form of a loop, and breaking in two later. The frequent branching of the short filaments causes them to become much distorted.
