CONFERVEE. 
23. Conferva fascicularis ? (Mert.—Ag. Syst. p. 114); filis 
ramosissimis capillaceis, ramis remotis subsimplicibus inferné 
nudis, ramulis fastigiatis densissimé fasciculatis secundis, 
articulis ramorum diametro 4—6-plo longioribus. 
I do not feel quite certain of the correctness of my reference 
| to Mertens C. fascicularis, which Ionly know through Agardh's 
short description and remark, ** Conf. glomerate et sericee 
proxima, sed differt ramis remotis brevioribus ;"—an observa- 
tion which answers pretty wellto my specimens. The fila- 
ments are 4— 35 inches long, forming elegant tufts, much 
branched; branches nearly bare of ramuli in the lower part, 
where the axillæ are very distant; in the upper, set with fas- 
cicles, which are mostly crowded round the apices. Colour 
a pale green. 
24. Conferva composita, (Harv. MS.); filis ramosissimis 
intricatis, ramis oppositis vel cruciatis patentibus bipinnatis, 
ramulis abbreviatis obtusis oppositis horizontalibus, articulis 
ramorum longissimis, ramulorum diametro duplo longiori- 
bus. 
A very pretty species, which I cannot refer to any described 
by Agardh. It is well marked by its bipinnate branches and 
opposite ramuli. Stems short, interwoven, much entangled ; 
branches opposite or ter-quaternate, spreading, branched more 
or less in a pinnate or bipinnate manner; the ramuli short, 
obtuse, patent. Articulations of the branches 10—12 times, 
of the ramuli twice, as long as broad. Colour a full green.
