fastigiata, axillis rotundatis, ramis patentibus dichotomo-multifidis, minoribus subalterne furcatis, margine 
integerrimo, apicibus angustatis subacutis, cystocarpiis marginalibus, tetrasporis in segmentis ultimis dis- 
persis.— Harv. Alg. Ersic. n. 910.

Frond 12 inches or more in length, and as much in the expansion of the branches, membranaceous, 1-2 lines 
in breadth in most of the branches and lesser divisions, excessively divided in a partly pinnated, partly dichotomous 
manner. The order of branching is primarily dichotomous, but by frequent suppression of one of the furcations the 
branches appear pinnated, with dichotomo-multifid lesser branches. All the azils are remarkably rounded. The 
frond in most places preserves a uniform breadth, but in some specimens it is twice as broad as in others. The 
margin is always free from lobes or cilia, and quite entire and flat. The apices are not remarkably acute. The 
colour is a very full, deep dark-red. Cystocarps are borne plentifully on the margin of the smaller lacinim, and 
tetraspores scattered through the substance of the ultimate divisions. The habit is not unlike that of some narrow 
specimens of Gracilaria multipartita.
