CYSTOPHORA BROWNII, /. A^. 



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. ScapJndia hermaphrodite. Spores obovoid. 

 — Cystophora (/. Ag.), from KV(m<i, a bladder, and (f)opeco, to hear. 



Radix scutata. Frons pinnatim decomposita, dendroidea, caule propria, rands 

 foUisque ramuliformibus donata. Vesicidce stipitat(e, simpUces, raro nullcB. 

 Receptacula siliquceformia, torulosa v. nodulosa, apice ramulo?'um evoluta. 

 Scaphidia hermaphrodita. 



Cystophora Brownii ; stem flat, decompound pinnate ; piunse issuing 

 from the flat side of the stem, bent down at their insertion ; pinnules 

 dichotomo-pinnate, the ultimate ramuli formed into minute, ovato- 

 lanceolate, torulose receptacles ; vesicles few, obovoid-spherical. 



C. Brownii ; caide piano decomposito-pinnato ; pinnis a latere piano caulis 

 egredientibus retrofractis ; pinnuUs dichotomo-pinnatis, idtimis in receptacula 

 ovato-lanceolata torulosa abeuntibus ; vesiculis raris obovoideo-sphcericis.

Descr. Root ? Stein 8-5 feet long, 2-3 lines wide, strongly compressed, or 

 flattened, slightly flexuous from node to node, alternately branched ; the 

 branches similarly compressed, and several times compounded in an alter- 

 nately pinnate manner. The branches are about an inch apart, and are 

 6-12 inches long or more, issuing from the flattened sides of the stem, and 

 strongly retrofracted at their insertion. All the minor divisions issue in 

 like manner, and are similarly retrofracted. The primary pinnules of the 

 pinnated branches are 2-3 lines apart, strongly compressed, their edges (in 

 the vertical plane) setaceous, their flat sides (horizontal) \ line wide : their 

 lesser divisions are subdichotomous, with vei-y wide axils, 1-2 lines apart. 

 The lower portion of each pinna, or primary branch, is generally denuded, 

 and alternately armed with the rigid, deflexed bases of old pinnules, set one 

 above the other like steps on a ladder. Vesicles very few, often absent, and
