Plate XLV. 
Fig. 205. PHYLLOPHORA RUBENS. 
Colour, A fine deep red. 
Substance. Stiff ; rigid ; thongh membranaceous. 
Character of Frond. Flat, leafy, narrow wedge-shaped ; forked or simple ; obscurely mid- 
ribbed at base ; throwing out secondary shoots of the same formation from the upper 
surface ; this second set throwing out a third in the same way ; and so on. The 
surfaces obstinately crumpled ; often covered with parasites. Tufted. 
Measurement. From 3 to 8 inches long. 
Fructification. Of two kinds. 1. Amass of spores in minute, roundish, wrinkled capsules; 
scattered on the surface. 2. Tetraspores in warts ^ formed at the base of small, 
leafy, scattered frondlets. 
Habitat. Our rocky shores generally ; but preferring the warmer stations. Under shelter of 
rocks near low-water mark. Frequent. 
Very handsome when not infested by Melobesias and Zoophytes ; hut always a rather 
unmanageable plant to lay out, and never adhering to paper. 
Fig. 206. PHYLLOPHORA MEMBRANIFOLIA. 
Colour. Purple, or purplish-red ; fading to green and yellow. 
Substance. Stems gristly ; frondlets membranaceous, but rigidly so ; especially when old. 
Character of Frond. Cylindrical, irregularly divided stems, bearing irregular branches, all of 
which expand into flat, fan-like, or wedge-shaped frondlets, more or less divided and 
forked. Margins sometimes smooth ; sometimes jagged with tiny leaflets ; especially 
above. Tufted. 
Measurement. From 3 to 12 inches long. 
Fructification. Of two kinds. 1. A mass of spores in egg-shaped capsules on short stalks, 
fringing the stems. 2. Tetraspores collected into large, dark, heart-shaped groups 
(son), in the lower half of the frondlets. 
Habitat. Our rocky shores generally ; but preferring the warmer stations. On rocks between 
tide-marks. Frequent.
