482 CALYMPEEACEAE. 



submarginal cells, basal cells large, clear, smooth, rectangular; upper cells 

 small, round, often jDapillose. Pedicel terminal, erect usually exserted; 

 calyptra campanulate or eucullate; lid long-beaked; peristome single of 16 

 short teeth or lacking. A family of mostly tropical mosses, containing 2 

 genera and about 313 species. 



Leaves with a sub-marginal border of long narrow cells on the 



hyaline base. 1. Cahjmperes. 



Leaves with a thickened or hyaline margin at base, which is often 



coarsely serrate or double above. 2. Syrrhopodon. 



1. CALYMPERES Sw.; Schwaegr. Suppl. T: 333. 1816. 



Plants in dense mats; stems crowded, simple or branching; leaves curled 

 and twisted when dry, base hyaline, often white and broader than the point, 

 the upper leaves often contracted into a narrow apex, bearing brood-bodies, 

 which serve to propagate the plants when sterile. Dioieous. Calyptra large, 

 covering the capsule, spirally ribbed and often rough at apex; lid beaked; 

 peristome and annulus lacking. [Named in reference to the large calyptra.] 

 About 200 species of tropical distribution. Type species: Calymperes loncho- 

 phyllum Schwaegr. 



1. Calymperes Richardi C. Muell. Syn. I, 524. 1849. 



Plants crowded in dark green mats, showing the white hyaline base of the 

 leaves when dry; leaves up to 3.5 mm. long, ovate-lanceolate, tapering to a 

 blunt point; vein stout, ending below the apex, papillose on both surfaces 

 above; submarginal border of 2-3 rows of cells^ extending to apex, not distinct 

 in the hyaline base; margins serrulate above. Dioieous. [Seta short, slightly 

 exserted; calyptra spirally ribbed 2 mm. long, persistent and clasping at base, 

 split above; capsule ovoid, cylindric; peristome and annulus none; lid conic- 

 beaked.] 



Only known sterile. On stumps in coppice, New Providence, Andros, Abaco 

 and Berry Islands, Great Harbor Cay : — Florida ; West Indies to tropical South 

 America. Richard's Calymperes. 



2. SYRRHOPODON Schwaegr. Suppl. 2-: 110. 1824. 



Plants growing in dense mats, frequently sterile and propagating by 

 brood-bodies. Stems crowded, simple or branching; leaves curled and twisted 

 when dry, crowded at the tips of the branches, with the upper part of the blade 

 dense and often papillose, the lower part lax and translucent ^vith large ree- 

 tanguar cells, the margins of thickened or of a double layer of cells, often 

 coarsely toothed; capsule erect, on a short terminal pedicel; peristome usually 

 present, single; teeth usually entire and papillose; lid beaked; calyptra eucul- 

 late, rough or smooth at apex. [Greek, in reference to the united teeth of the 

 peristome.] About 215 described species, tropical and subtropical. Type 

 species: Syrrliopodon Gardneri Hook. 



1. Syrrhopodon Gaudichaudii Mont. Ann. Sci. Nat. II. 2: 376. pL 16. 1834. 



Plants pale yellowish-green, with the white bases of the leaves very con- 

 spicuous. Stems simple or with short crowded branches; leaves curled and 

 twisted at apex, about 2 mm. long; base with 5-6 rows of large rectangular 

 hyaline cells on each side of the vein and the margins bordered by narrower
