    Species Description - Plants filiform to medium size, olive-green, more or less pigmented with dark brown, often becoming reddish; stems slender, 2-8 cm long, with leaves to 2 mm wide, prostrate to ascending; branches 1 cm or more apart, diverging at an acute angle; flagelliform branches numerous, long. Line of insertion curved in the upper half. Leaves distant to imbricate, spreading to ascendent or curved around the stem, persistent, asymmetric, ovate-triangular, to 1 mm long, to 0.6 mm broad at the base, narrowing to the acute or obliquely truncate, 3-toothed (sometimes 2-toothed) apex, the acroscopic tooth longest; teeth two to six cells long, one or two to five cells broad at the base; leaf-cells thin-walled, the trigones small, the lumina rounded, the cuticle smooth to slightly verruculose; cells of the apical portion 20-26 X 22 µ. Underleaves distant to approximate, squarrose, broadly quadrate-orbicular, as wide as or wider than the stem, to 0.35 mm long, 0.45 mm wide, the apex usually undulate to four-lobed, the lateral margins undivided to occasionally irregularly lobed or toothed. Male and female branches and sporophyt.es not seen on the Central American material. Fig. 23, a-c.

  • Discussion

    Jungermannia tricrenata Wahlenberg, FI. Carpat. 364. 1814. [The long synonymy for this species is given in works on Hepaticae of North America or of Europe.] This is the first record for this species south of the United States, and the first record for any northern species of Bazzama in Latin America. It becomes another in the list of examples of plants that has a discontinuous distribution that includes eastern (and western) North America and the Highlands of Mexico-Quatemala.
