j22 CRYPTOGAMIA ALGiE. 



On trunks of trees very common. III. IV. 



'i'his adheres clofcly to the bark of trees, in the 



fame manner as the preceding, but differs froni 



it in the following particulars : 



It is either of a dark green or a red brown co- 

 lour, more branched than the other ; the branches 

 more (lender, efpecially at their bafe, but di- 

 lated, and clofely imbricated towards their ex- 

 tremities-, whereas thofe of the other are of equal 

 breadth throughout. The leaves are not above 

 half fo large, are convex above, and concave 

 beneath, and not of fo flcxcid a texture as the 

 preceding. The nerve on the under fide is 

 loofely imbricated with an alternate feiies of 

 round fcales, or auricles, larger than thole of 

 the foregoing, and but little Icff than the upper 

 leaves of this, which give the under furface a 

 crifped appearance. 



The frucftiiications a rife at the extremities of th* 

 branches, 'i he vagina are more turgid and an- 

 gular ; the pedum ics fiiorter, hardly a line in 

 height; the tf«//^^y^ fmaller, fufcous, and divid- 

 ing into four hairy fegments.
