similis, ramificationem habet irregularem, folia hyalino-viridia ovalia 
subacuta, lobulo imo minore (= lobi 3-4); bracteolas minores (‘75™™ 
longee); ceterum, quoad partium magnitudinem texturamque, foliolorum 
forma, ete., certe proxima. 
Obs. L. Spongia forms globose tufts, like sponges, pale green without, 
white within, and always saturated with water, on the twigs of low trees 
(Clethre, Weinmannie, &c.) on mount Tunguragua, at 8000 to 9000 Eng.
