Lyngbya splendens sp. now

Plate 9, figure 81

Filaments forming a thin pannose stratum on the surface of
the soil, long, relatively straight, gently arcuate, 17-20 p diaiii.;
trichomes 14-16 m diam., not constricted; apices not attenuated;
cells one-fourth to three-fourths as long as broad, uniformly and
very finely granular, color aeruginous, cross-walls very thin but
¡distinct; apical cell rounded, at times slightly narrower; termi-
nal wall not thickened; sheath thin, smooth, homogeneous, hya-
line at first, changing to salmon-pink.

: Growing on tree trunks on the way towards Monte Montoro,
Maricao, no. 1072, type.

Lyngbya splendens seems to be a very distinct species. The
color of the sheath resembles that of some species of the genus
Porphyrosiphon, but structurally it is more like a typical Lyng-
? bya sheath. The trichomes are typical of the genus Lyngbya.
It is probably closely related to L. major.
