^P2 CRYPTOGAMIA ALG^E. 



On trunks of trees very common. III. IV. 



This adheres clorely to the bark of trees, in the 



fame manner as the preceding, but differs from 



it in the follow.ng particulars : 



Ir is eitiier of a daik green or a red b^own co- 

 lour, more branched than the other ; the branches 

 more iknder, cfpccially at their bafe, but di- 

 lated, and clofcly i.mbricated towards their ex- 

 tremities ; wliereas thofe of the other ^re of equal 

 breadth throUi<hout. The leaves are not above 

 half fo large, are convex above, and concave 

 beneath, and not of fo flcccid a texture as the 

 preceding. The nerve on the under fide ia 

 loofeiy imbricated v.iih an alternate feries of 

 round fcalcs, or auricles, larger than thofe of 

 the forenomg, and but little Itfs than the upper 

 leaves of this, vvhich give the under furface a 

 crifped appearance. 



The frudilications arife at the extremities of the 

 branches. The vagi)hc are more turgid and an- 

 gular i the i^edunclcs fliorter, hardly a line in 

 height i the anther^ fmaller, fufcous, and divid- 

 ing into four han-y fcgments.
