CYSTOPHORA SONDERI, 7 47. 
Gen. Cuar. Root scutate. Frond pinnately decompound, dendroid, with 
a distinct stem, branches, and ramuliform leaves. Vesicles stipitate, 
simple, rarely absent. feceptacles pod-like, torulose or moniliform, 
developed in the ramuli. Scaphidia hermaphrodite. Spores obovoid. 
—Cystornora (J. Ag.), from xvotis, a bladder, and dopew, 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. 
CysropHora Sonderi; root scutate; stem terete, mostly undivided ; 
branches spreading in every direction, pinnately ramulous, filiform, 
the ultimate ramuli changing into short, ovato-lanceolate, scarcely 
torulose receptacles; vesicles between spherical and ellipsoidal, api- 
culate, about one on each pinnate ramulus. 
C. Sonderi; radice scutata; caule terete sepius indiviso ; ramis undique egre- 
dientibus pinnatim ramulosis filiformibus, ramulis ultimis in receptacula brevia 
ovato-lanceolata via torulosa abeuntibus ; vesiculis ellipsoideo-sphericis apt- 
culatis in ramulo pinnato subsingulis.

Descr. Root an expanded disc, an inch or more in diameter. Stem either un- 
divided or divided near the base into several long, simple, stem-like branches, 
as thick as crow’s-quill or thicker, more or less stripped above the base, 
and there rough with short, hard, prominent points, being the persistent 
stumps of broken branches, attenuated upwards, and tapering into a seta- 
ceous point, closely beset with lateral branches throughout the greater part 
of its extent. Branches 3-6-8 inches long, horizontally patent, spreading 
to all sides of the stem, and not deflexed at their insertion, closely pinnated 
with alternate pinnules. Pénnules filiform, dichotomo-pinnulate or multifid, 
about uncial, their ultimate divisions setaceous with rounded axils. Vesicles 
about a line or 12 line in diameter, globose or oval, on long, filiform, slen- 
der petioles, mucronate, two or more on each multifid pinnule. eceptacles 
2-3 lines long, aggregated, sometimes bifid, ovato-lanceolate or fusiform, 
somewhat torulose, much shorter than the ramuli by which they are sub-
