cymose inflorescences being thus formed; bracts slightly spreading, 
scarcely keeled, the lobe straight (not falcate), ovate, mostly 
0.85-1.1 mm. long and 0.35-0.55 mm. wide, acute and usually 
irregularly toothed, the teeth small, sharp or blunt, rarely more 
than three or four and often vague or indistinct, lobule usually 
indistinct, represented by a short and narrow basal fold, the 
apex rarely distinguishable but sometimes acute; bracteole free 
or nearly so from the bracts, ovate to obovoate, mostly 0.7—1 mm. 
long and 0.45—0.6 mm. wide, bifid about one fourth with a narrow 
acute sinus and erect, acute lobes, the margins as, in the under- 
leaves, rarely with a median sharp or blunt tooth on one or both 
sides; perianth more or less exserted, sometimes for about half its 
length, obovoid and often narrowly so, mostly 0.6—0.75 mm. long 
and 0.3-0.35 mm. wide, cuneate toward the base and truncate 
at the apex with a rather long beak, five-keeled in the upper 
third, the keels sometimes rounded and indistinct but often 
sharper and more or less distinctly winged, a wing sometimes 
bearing one or two short and irregular teeth: @ inflorescence 
occupying a short branch, usually arising in a @ inflorescence 
branch-system, sometimes in the form of a subfloral inno- 
vation, apparently never proliferating; bracts mostly in one to 
five pairs, imbricated, much smaller than the vegetative leaves, 
strongly inflated, shortly bifid with blunt or subacute lobes and a 
strongly arched keel; antheridia in pairs; bracteole mostly single, 
very small, ovate bifid about one third with subacute lobes: 
mature sporophyte about 0.2 mm. in diameter. [TEXT-FIGs.

On wet rocks; range incompletely known. The following 
specimens have been examined: 
JAMAICA: near spring and waterfall, vincinity of Moody’s Gap, 
September, 1908, E. G. Britton 938; on wet rocks, Hardware 
ap and vicinity, July, 1903, A. W. Evans 204; on wet rocks, 
Doll Wood, August, 1906, A. W. Evans 485; on Asplenium alatum 
H. B. K., growing on wet rocks, trail from Morce’s Gap to Vinegar 
Hill, March, 1920, Maxon & Killip 1318a. 
CoLomsiA: Cerra de Onaca, August, 1898, H. Wf) Smith ‘‘D.” 
Mrs. Britton’s specimen from Moody’s Gap, Jamaica, No. 
938, may be designated the type. 
The branch-systems upon which the female inflorescences 
are borne sometimes attain a high degree of complexity and con- 
stitute one of the distinctive features of the species. In their 
simpler states these branch-stysems resemble those of T. jamaicen-
