and repeatedly divided ; the ramuli slender, few and subdistant. The articulations of the 
branches are very many times longer than broad ; those of the ramuli 5-6 times their 
breadth. The endochrome is generally dissipated in drying. When dry the specimen 
retains a brilliant green and has a silky gloss. 
14. Cladophora gracilis , Griff.; filaments very long, capillary, flexuous, silky, much 
branched, bright yellow-green ; main branches entangled, sparingly divided, angularly 
bent ; ultimate ramuli pectinate, secund, much attenuated, straight, and very long ; 
articulations 3-5 times as long as broad. Griff, in Wyatt , Alg. Damn. No. 97. Harv.

Filaments more or less densely tufted, 4-12 inches long, (about 4 inches in the 
American specimens), capillary, soft and silky, much branched ; the main branches 
rather more robust and bent in a zigzag manner, sometimes very flexuous, and fre- 
quently more strongly coloured than the rest of the plant, set throughout with lateral, 
decompound branches all whose divisions are patent ; and the ultimate branchlets 
pectinated with long, simple, secund ramuli. Colour a yellow-green. Substance soft 
and silky, but not gelatinous. Articulations 3-5 times as long as broad. It does not 
strongly adhere to paper in drying. 
Mrs. Mudge’s specimens are small, but in other respects very similar to English 
ones. Those from Mr. Olney and Mr. Ashmead are less true to the type. 
15. Cladophora brachyclados , Mont. ; filaments very slender, tufted, sparingly 
branched ; branches long and virgate, set with distant, alternate, erecto-patent branch- 
lets, which are pectinated along their upper sides with very short, erect, or incurved 
ramuli, of 1 or 2 cells ; articulations of the branches 5-6 times as long as broad. Mont.

Hab. Mouth of Rio Bravo, on the sea-beach, Dr. Schott, (v. s. in Herb. T.C.D.) 
The specimen received from Dr. Schott is a very imperfect one, but its filaments, 
when examined under the microscope, show so many characters in common with those 
of Montagne’s C. brachyclados from Cuba, with an authentic specimen of which I have 
compared them, that I am unwilling to separate forms sp similar. The short, mostly 
single-celled ramuli are characteristic.
