RED ALG^. 147 



Jointed in the upper half, as are also all the branches. 

 Sometimes there is a main leading stem and some- 

 times not. The branches are irregularly placed, but 

 divide and sub-divide in a manner between forking 

 and branching. 2. The axils of the sub-divisions 

 are narrow, so that the branchlets seem to cluster 

 together. 3. Owing to the great length of the 

 secondary branches and branchlets, the plant gives 

 the impression of reaching out and trying to extend 

 itself. 4. The branches seem to maintain their orig- 

 inal thickness almost to the tips. 5. On the ulti- 

 mate branchlets will be found many short ramuli, 

 which taper to base aad apex like those of Chon- 

 driopsis temiissijna. 6. Growing mostly through the 

 same regions as P. violacea, it is yet, as compared 

 with that species, if not distinctly rare, certainly 

 very infrequent. 



The winter form of this plant, when the finer 

 branchlets are fallen away, is an exaggeration of 

 some of its summer aspects. The great length of 

 its bare, slender, unclothed branches gives it a pecu- 

 liar and really uninteresting appearance. In this 

 state the natives call it "lobster horns," or "lob- 

 ster claws," because of its supposed resemblance to 

 the long, slender antennce. of that creature. The 

 winter plant very imperfectly ac^heres to paper.
