Forming dense cream-coloured cushions on 

 ledges of rocks and trees. 



This species is said to differ from L. cupressina 

 in the bipinnate, less attenuated ramuli, and 

 broader leaves. Irish specimens vary much both 

 as to size, ramification, and shape 

 of the leaves. Some stems are 

 distantly and irregularly branched, 

 and scarcely distinguishable from 

 L. reptans, while others are densely 

 pinnate, bi- or even tri-pinnate, ac- 

 cording to age and luxuriance, new 

 stems springing from the old in a 

 proliferous manner. The involucral 

 leaves are variable in shape, obtusely 

 tridentate, the central tooth reflexed, 

 with larger rhomboid areolae than on 

 the stem leaves. From L. reptans it 

 is distinguished by the dense erect 

 habit (fig. 65), closely pinnate ramuli, subvertical 

 cordate leaves, which, like the stipules, are quadri- 

 fid (fig. 67), the ventral teeth inflexed, areolae
