Distribution and Ecology - Growing on a very small species of Hepaticae on limestone, Hato Arriba, Arecibo, no. 1415 a, type; Coamo Springs, no. 282 d.

Discussion
PLATE 12, FIGURE 16
It is unfortunate that the material is not producing resting spores so that the whole life history might be given of this very diminutive, though distinct, species of Nodularia. It apparently is closely related to N. Harveyana (Thwaites) Thuret, but has much shorter cells.
