frequently in a subpinnatifid manner ; some of the minor ones being se- 
cundly multifid, others pinnate. The axils throughout are rounded, and 
the apices more or less acute. The margin is smooth and flat, or slightly 
undulate, sometimes bearing proliferous, lanceolate leaflets. Cystocarps very 
numerous and prominent, globose, thickly scattered over the surface, prin- 
cipally in the middle region of the frond, sometimes covering the lateral 
segments. edraspores unknown. Colour, a vivid rosy or blood-red, or a 
deep lake. Swdstance, rather thickish membranous, soft, succulent, closely 
adhering to paper in drying. 
In 1855 I collected a few specimens of this plant, without 
fruit, and, guided by external habit, referred them provisionally 
to Callophyllis ; but a fine specimen in fruit recently received 
from Mrs. Barker proves the plant to be properly referable to 
Rhodophyllis. 1 take advantage of this change of generic name 
to alter the specific name also ; and in now dedicating the species 
to Mrs. Barker, I wish to present my best thanks to that lady 
for several parcels of well selected and admirably preserved spe- 
cimens of Algee, collected at Cape Shank, a locality as yet unvi- 
sited by any other collector. I am also indebted to Dr. Miller 
for his kindness in transmitting Mrs. Barker’s parcels.
