Cystophora Grevillei (Ag.) J. Agardh. 
^ Stem terete, compoundly pinnate. Pinnae less evidently retrofract. 
Vesicles singly on a pinna stalked, as large as a garden pea, or larger, 
spherical, mutic. Receptacles pod-like, to 5 cm., even exceptionally 12 cm., 
long and 23 mm. wide, compressed, incurved, with antheridia and oogonia 
in distinct conceptacles. Tall, to over 1 metre high. 
Western and South Australia, Victoria?, Tasmania. 
aa. Conceptacles more scattered, not confined to two linear series. 
c. Stem flattened, the rachis dorso-ventrally compressed, giving off 
pinnate much divided branches from the sharp edges of the rachis. 
Cystophora spartioides (Turn.) J. Agardh. 
Developing in one plane. Pinnules dichotomously pinnate. No vesicles. 
Receptacles 1 to 2.5 cm. long cylindraceous, warted, with scattered con- 
ceptacles. Several feet high. 
South Australia, Victoria, Tasmania, and southern New South Wales. 
cc. Stem flattened laterally, the pinnae emerging from the plane faces. 
Cystophora Brownii (Turn.) J. Agardh. 
Pinnae retrofract, pinnulate, the ultimate divisions of the pinnules 
dichotomous. Vesicles “extremely rare, and chiefly from the lower parts, 
obovate-spherical of the size of seeds of Abrus precatorius ” — De Toni. 
Receptacles unique in the genus, very short, less than 4 mm. long, ovate- 
lancoid gradually attenuated at the apex, with scattered conceptacles. To 
over 1 metre high, distinguished by the delicate tracery of the pinnules. 
Western and South Australia. 
Cystophora monilifera J. Agardh. 
I innac retrofract, 30 cm. long, lax and flaccid, decompound pinnate, the 
pinnules dichotomously pinnate. Vesicles numerous, nearly spherical, 
mutic, the size of a pea. Receptacles very slender with a filiform rachis, 
to 2 cm. long, moniliform with swellings at greater or less distances, much 
thicker than the thread-like rachis. Conceptacles numerous, approximate. 
Several feet high.
