Species Description - Trichomes epiphytic, firmly attached, few at first, mostly parallel and contiguous, extending lengthwise of the host, later completely surrounding it and in places becoming more than one layer deep, brought about by secondary growth of intercalary cells; cells subspherical, 5-5.3 n diam., usually less than the diameter in length; heterocysts spherical or compressedspherical, 6-6.3 µ diam.; spores unknown
Distribution and Ecology - Growing on other filamentous algae in a pool near the Experiment Station, Eio Piedras, no. 1947, type, no. 154 b, and no. 1946 a.

Discussion
Unfortunately the complete life history of this species of Anabaena cannot be given at this time, the material having no resting spores. The size and structure of the trichomes, combined with the habitat (growing firmly attached to other plants, e.g., Oedogonium in the case of no. 1947) seem to warrant giving the material specific rank.
