A new Lejunea from Bermuda and the West Indies * 
ALEXANDER W. Evans 
(WITH PLATE 24) 
The species described below is not uncommon in the West 
Indies and is perhaps to be expected in Florida and Mexico. It 
seems to be most abundant at low altitudes, without being strictly 
coastal in its distribution. The material at first examined, which 
was scanty and incomplete, was confused with L. glaucescens 
Gottsche, and some of the Bermuda specimens have been listed 
under this name by the writer. More abundant material has 
since been available and has shown conclusively that the species 
is amply distinct. 
Lejeunea minutiloba sp. nov. 
Pale or dull green, often somewhat brownish with oi ee 
or growing in depressed mats: stems about 0.1 mm. meter, 
copiously and irregularly branched, the branches bhianele to 
widely spreading, often with slightly smaller leaves than the stem 
but not microphyllous: leaves contiguous to loosely imbricated, 
the lobe widely spreading, slightly falcate, plane or slightly con- 
cave, broadly ovate, when well developed about 0.5 mm. long and 
0.45 mm. wide, dorsal margin usually arching partially or wholly — 
across the axis, then strongly outwardly curved to the broad and 
ed 
projecting cells; lobule in the form of a minute triangular basal 
fold, consisting of only a few cells, the apex represented by a 
single projecting cell tipped with a hyaline papilla; cells of lobe 
averaging about 13 u in diameter at the margin and 25 X 20u in 
the median and basal portions, thin-walled but with minute 
trigones and occasional intermediate thickenings, cuticle smooth: 
underleaves distant, orbicular, about 0.2 long, bifid about one 
alf with erect, triangular, acute, obtuse or rounded divisions, 
rounded at the base, margin as in the leaves: inflorescence autoi-
