Description of the species. A well grown plant of the 

 present species measures 5-6 feet in length, attached to the 

 substratum by a circular disc which is slightly elevated at the 

 to]). PI. II. fig. 5 shows a young shoot just starting out. In 

 this sort of plant the stem at the basal region is smooth and 

 cylindrical, not exceeding a few inches in length. The primary 

 stem is subclavate, with a number of fusiform, approximate 

 branches near the top as well as around the swollen portion. 

 The morphological characters of these fusiform branches are 

 identical with those described under the preceding species. 



The lateral branchlets which start from the lower portions 

 of the fusiform branches are more or less thiciv and robust,
