392 WILLIAMS: CALYMPERACEAE OF NorTH AMERICA 
cylindric border of short-rectangular, green cells extending from a 
little below the apex to the erect or clasping basal part; costa 
nearly cylindric, about 65 » wide one third up from base, papillose 
on both sides to cancellinae, usually shortly excurrent, slightly 
enlarged at the apex and bearing numerous, short, spindle-shaped 
propagula about 120 y long, with six to eight transverse walls; 
cross-sections of costa show about four guide-cells, stereid bands 
above and below of rather large cells, and outer cells differentiated 
on upper side; leaf-cells of spreading blade mostly not elongate, 
the median 4-6 y,in diameter, mamillose on upper side, slightly or 
not mamillose but more or less papillose on under side; teniolae 
wanting; cancellinae extending about one fourth up leaf, truncate 
or somewhat rounded above, mostly four to six rows of cells wide on 
either side of costa and extending about one half way from costa 
to margin with the small green cells of blade above descending 
on outer side in a broad band to or near base; fruit unknown.

Tyre collected in Hayti on trees at sea-level near Port Margot, 
August, 1903, G. V. Nash 51 (herbarium of the New York Bo- 
tanical Garden). 
DIsTRIBUTION: Hayti, Mona Island and Florida (on hammocks, 
Adams Key, Dade County, March, 1915, Small & Mosier 5158): 
This species is much like some of the small forms of C. Richardt 
growing in similar situations, but teniolae are entirely wanting, 
the leaf-border is entire and the cancellinae are narrower.

In large tufts or mats with stems up to 3-4 cm. high; stem- 
leaves 4-5 mm. long, flexuous or crispate when dry, erect-spreading 
when moist, from an ovate or obovate, mostly much broader base 
narrowed to a linear-lanceolate point about three times longer, 
the upper surface mamillose, the under smooth, with leaf margms 
entire or nearly so all round and much thickened from apex to the 
clasping base; costa stout, nearly percurrent, smooth on both 
sides, often with propagulae on upper side near apex; cross-sections 
of leaf near middle show a nearly semiterete costa. with five oF 
six guide-cells, stereid bands above and below. and outer cells 
differentiated, with a nearly cylindrical leaf-border composed
