Gen. Char. Root scutate. Frond pinnately decompound, dendroid, with 

 a distinct stem, branches, and ramuliform leaves. Vesicles stipitate, 

 simple, rarely absent. Receptacles pod-like, torulose or moniliform, 

 developed in the ramuli. Scaphidia hermaphrodite. 8pores obovoid. 

 — Cystophora (/. Ag^, from Kvart^, a bladder, and (f)ope(o, to bear.

Cystophora cephalornithos ; stem terete, simple, warted ; branches issuing 

 from all sides, pinnately divided ; ramuli filiform, the uppermost 

 changed at their summits into terete receptacles; vesicles fusiform, 

 setaceo-mucronate, issuing from the stem or larger branches.

Descr. Root a small disc. Fronds tufted, 2-3 feet long. Stem filiform, l-f 

 line in diameter, simple, denuded in its lower part, and there warted or 

 muricated with the remains of old branches, densely beset in its upper half 

 with short, laterally patent or subhorizontal branches issuing to all sides. 

 The general outUne of the frond is oblong and brush-like. In smaller speci- 

 mens the lateral branches are simply pinnate, with a few slender, simple, 

 filiform ramuli ; in the larger the branches are longer, 5-6 inches long, and 

 more or less bipinnate. The vesicles are copious, on long or short petioles, 

 narrow-ovoid or fusiform, tipped with a longish bristle, and they are borne, 

 along with the branches, on the stem ; in the larger specimens, however, 

 tliey often occur among the ramuli on the lateral branches. The receptacles
