REMARKS

Syzygiella campanulata was recorded from Costa Rica, Venezuela, Colombia, Ecuador, Bolivia and the Dominican Republic, growing usually on tree trunks in upper montane forest at 2000-3700 m ( Inoue 1966; León et al. 1998; Schäfer-Verwimp & Pócs 2009; Feldberg et al. 2010). The species is characterized by plants c. 2 mm wide, leaves ventrally and dorsally opposite and connate, ovate, entire, ventral and dorsal bases shortly decurrent, leaf cells with large, nodulose trigones and cuticle strongly papillose, with 10-20(-30) rounded papillae on each cell. Another important characteristic is the long-exserted perianth, c. 5 mm long, with bracteoles united with the bracts for more than 2/3 of their length ( Inoue 1966).
