210 Evans: THE HEPATICAE OF THE BAHAMA ISLANDS 
sometimes occupying the entire length of a short branch, often 
proliferating; bracts mostly in two to six pairs, imbricated, in- 
flated, subequally bifid with a strongly arched keel and rounded 
divisions; bracteoles extending the whole length of the inflorescence, 
similar to the underleaves but smaller and usually with more ir- 
regular margins; antheridia in pairs: capsule about 0.3 mm. in 
diameter; spores minutely verruculose, about 124 inshort diameter; 
elaters about 74 wide. (PLATE 9, FIGURES I-12.)

type. The species is included under Cheilolejeunea phyllobola 
in Coker’s list. 
In the various species of Rectolejewnea vegetative reproduction 
is accomplished by means of leaves which break away from the 
stems and branches and attach themselves to the substratum 
by scattered rhizoids. The latter grow out directly from marginal 
leaf cells and sometimes make their appearance before the leaves 
become separated. The deciduous leaves give rise to new leafy 
shoots by a process of regeneration. In most cases a leaf will 
bear but a single leafy shoot, although two or even three are oc- 
casionally developed. Apparently a shoot always arises from a 
marginal leaf cell. 
In R. flagelliformis Evans,* of Cuba and Porto Rico, and 
also in R. Berteroana the deciduous leaves are strikingly modi- 
fied and are borne on peculiar flagelliform branches with short 
internodes and limited growth. These branches spread at
