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. f 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 age, scattered 

 or growing in depressed mats: stems about o.i mm. in diameter, 

 copiously and irregularly branched, the branches obliquely 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 

 rounded apex, ventral margin straight or slightly outwardly 

 curved, margin entire or vaguely and minutely crenulate from 

 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 n in diameter at the margin and 25 X 20/1 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 

 half with erect, triangular, acute, obtuse or rounded divisions, 

 rounded at the base, margin as in the leaves: inflorescence autoi-
