LEAFY HEPATICAE OF LATIN AMERICA — PART III 



333 



part incurved, subimbricate, bilobed to one-half their length, the dorsal segment 

 long triangular from a 3- to 4-celled base, ciliate, capillary, ending in a row of 4-6 

 cells, the ventral segment usually a row of 5 or 6 cells, the segments connivent, often 

 overlapping, the sinus lunulate, the margin with two or three 2-celled cilia, the 

 ventral sac rounded, extending beyond the stem; cells of the segment tips 40-50 X 

 15 fi, of the segment base 25, 35-40 X 15-20 y,, the walls uniformly thickened, the 

 cuticle essentially smooth. Underleaves absent. Female inflorescence on a short 

 ventral branch, the bracts and bracteoles in three series, long-ovate, keeled, bilobed 

 above, the segments acute, the margins setulose and ciliate with 2-celled cilia. Peri- 

 anth long, 3-keeled above, the mouth not contracted, truncate, setulose and ciliate 

 with 3-celled cilia. Male inflorescence not seen.

I s : 96. 1893. 



Cephalozia subg. I. Proto-Cephalozia Spruce, On Cephalozia 24, 1882. 



Vegetative plant small, light green, branched-filamentous (a prolonged per- 

 sistent protonema from a Cephalozia-type sporeling) suggesting the protonemata of 

 certain mosses; filaments uniseriate, rarely 2 cells wide near the base. Rhizoids 

 absent. Plants monoicous or dioicous, the inflorescences foliaceous. Male inflores- 

 cence terminal or lateral, the long curved branch with to 10 series of bracts, with 

 rhizoids scattered over the ventral side of the axis; bracteoles absent. Antheridial 

 stalk uniseriate. Female inflorescence never terminal on a filament, rhizoids abun- 

 dant at the base, the bracts and bracteoles tristichous, in 2 or 3 series, the inner 

 series longest, long-ovate, bifid to one-half their length. Perianth long, 3-keeled 

 above, the mouth of 6 long slender segments similar to those of the bracts and 

 bracteoles. Shoot-sporophyte relationship a shoot/calyptra. Capsule small, dark, 

 oblong in outline, the wall of 2 layers with characteristic markings; seta in trans- 

 verse sections mostly 4 cells across, an outer layer of 8 rows and an inner core of 

 4 cells.

 Pflanzenf. I 3 : 96. 1893. 



Cephalozia ephemeroides Spruce, On Cephalozia 24. 1882. 



Vegetative plants in small, light green, much branched filamentous mats; fila- 

 ments uniseriate, the cells rectangular in outline, the cuticle papillose. Rhizoids 

 absent except on the male and female branches. Plants monoicous or dioicous. Male 

 inflorescence terminal or lateral on a filament, the long curved branch bearing to 

 10 series of male bracts, with scattered rhizoids along the ventral side; bracts small, 

 imbricate, broadly ovate, concave, more or less folded, bifid to one-third their length,
