CYSTOPHORA MONILIFERA, J. 4. 
Gen. Cuar. fooé scutate. Frond pinnately decompound, dendroid, with 
a distinct stem, branches, and ramuliform leaves. Vesic/es stipitate, 
' simple, rarely absent. Receptacles pod-like, torulose or momiliform, 
developed in the ramuli. Scaphidia hermaphrodite. Spores obovoid. 
—Cysropnora (J. Ag.), from cvotis, a bladder, and gopew, to bear. 
Radix scutata. Frons pinnatim decomposita, dendroidea, caule proprio, ramis 
foliisque ramuliformibus donata. Vesicule stipitate, simplices, raro nulle. 
Receptacula siliqueformia, torulosa v. nodulosa, apice ramulorum evoluta. 
Scaphidia hermaphrodita. 
Cystopuora monilifera; root scutate; stem flat, decompound-pinnate ; 
pinne issuing from the flat side of the stem, bent down at their in- 
sertion, at base alternately obtusely aculeate ; pinnules dichotomo- 
pinnated, the ultimate changed into nodoso-moniliform, slender, api- 
culate receptacles ; vesicles numerous, between obovoid and spherical, 
pointless.

Descr. Root scutate. Stem several feet long, decompound, flattened, 2-3 lines 
wide, the branches proceeding from the flattened side and bent down at 
their insertion; a peculiarity which runs through all parts of the frond. 
Primary branches or secondary stems 3-4 feet long, pinnated at intervals 
of about an inch with very patent, closely-branched and decompound pinne. 
These pinne are usually bare at base and there set with alternate, rigid, 
blunt prominences, being the bases of broken branchlets ; they are either 
once, twice or thrice pinnulated, the more divided specimens becoming 
very dense in ramification. The ultimate pimnaules are multifid, between 
pinnate and dichotomous, and are slender and almost setaceous. Vesicles
