Plate VIII. 
Fig 29. LAMINAKIA PHYLLYTIS. 
Colour. Pale, yellowish green. 
Substance. Thin and tender ; delicately membranaceous ; retaining these characters when old. 
Character of Frond. A flat, leafy expansion ; ribless ; growing from a stem. Stem^ always 
short in proportion to the expansion. Expansion., ribbon-like, very long and narrow, 
tapering gradually at each end. Margins wavy at times, yet scarcely as much curled 
as in L. saccharina. Koot, fibrous. 
Measurement. Stem, from 1 to 2 inches long. Expansion, from 8 inches to 3 feet long ; from 
1 to 6 inches wide. 
Fructification. Minute seeds (^spores) imbedded here and there in the surface of the frond, 
thickening it, and forming cloudy patches. 
Habitat. Our coasts generally. Between tide-marks, and at extreme low-water, on rocks and 
in pools left by the tide. Not uncommon. 
The tapering ends and more marked narrowness throughout, are guides to this plant, as 
well as its very delicate substance. When grown to its greatest length it never becomes 
leathery, coarse, or brown, like L. saccharina. Tufts of it grow together among boulders at 
extreme low'-water mark, as on The Spittals, Filey. 
Fig. 30. LAMINAEIA FASCIA. 
Colour. Olive, or olive-brown. 
Substance. Membranaceous, but not quite so delicate as L. Phyllytis. 
Character of Frond. A flat, leafy expansion ; ribless ; growing from a stem. Stem, very 
short. Expansion, often widening upwards, becoming blunt at the end ; sometimes 
narrow throughout ; sometimes wider below, and tapering upwards. Boot, a minute 
disk. 
Measurement. Stem, when longest, J an inch ; passing insensibly into the frond. Expansion, 
from 4 to 12 inches long. Width, from ^ of an inch to an inch or two. 
Fructification. Minute seeds {spores) imbedded here and there in the surface of the frond, 
thickening it, and forming cloudy patches. 
Habitat. Our shores generally. On mud-covered rocks. Not uncommon. 
The little disk-like root stamps this species whenever it can he found ; and the thick, 
dark, olive hue is another strong feature.
