branches short : leaves broadly Ungulate, rounded at apex, some- 

 what undulate, unsymmetrical, costa far to one side : tip somewhat 

 wavy, minutely serrulate : costa slender, ^ length of leaf : cells 

 irregularly massed at tip, oblong at middle, narrowed at base : 

 synoicous : outer perichaetial leaves ovate-acuminate, apical cells 

 roughly triangular, basal and middle sinuous : inner perichaetial 

 leaves narrow-acuminate, equaling or exceeding the capsule serru- 

 late at apex, with narrow, sinuous cells. Sporophytc : capsule, im- 

 mersed, or sub-emergent, urn-shaped : calyptra small, smooth ; 

 lid conical-acute, oblique : teeth pale, narrow lance-subulate, min- 

 utely wrinkled : segments equaling teeth, not keeled. (From

This species is easily distinguished from the nearest North 

 American species, E. Jamaicensis, by its smaller, very unsymmet- 

 rical leaves, as well as by its more slender stems and smooth calyptra. 



Replace the " (Sw.) " by " (Hedw.)" if Hedwig be taken as 

 the starting-point for nomenclature. 



6. Eleutera Jamaicensis (Gmel.) nom, nov. 



GamctopJiyte soft, yellowish -green : primary stems short: 

 secondary stems short, 1-2 cm. in length, usually simple : leaves

 oblong-lingulate, truncate, transversely undulate, very minutely 

 serrulate : costa slender, 4/5 length of leaf : cells at tip small and 

 irregularly massed, in middle oblong, at base narrow : synoicous : 

 outer perichaetial leaves ovate, abruptly acuminate, inner narrow, 

 linear, ecostate or short-costate, sub-serrulate, equaling the cap- 

 sule. Sporophyte : capsule small, sessile, cylindrical-oblong, im- 

 mersed : calyptra small, covering lid only, with few hairs ; lid 

 conical, oblique, short-beaked : teeth and segments free to base, 

 nodulose, punctulate. (From Latin, of Jamaica?)
