Acetabularia
moebii Solm Lauback
Characteristics
The alga
are found just below mea lwtide level, growing attached to calcium
encrusted basaltee rocks in the intertidal region. It usually grows
in the crevices between rocks or in the lee side of the rocks shielded
from wave action
The plants
are short with short stalk ranged from 1.08 mm to 3-7 mm in length
and about 400µ in diameter, rugose, gradually tapering towards
the base and ending in a much branched rhizoidal system.
The rhizoids
are 100 - 125µ broad. The stalk is surrounded by a circular,
flat or umbrella like crown, 1.97 mm to 3.15mm in diameter and consisting
of 15 - 17 subcoalescent cystosporangial rays. Each ray is 0.67 mm
to 1.3 mm long, 0.29 mm to 0.5 mm broad at the rounded distal end
and 0.14 mm to 0.16 mm wide at the narrower base.
The superior
corona alone is present and consists of 15 - 17 knob-shaped segments
70 -90 µ in diameter. Each coronal knob bears a circular roup
of 5-6 hai scars indicating the places of attachment of the deciduous
hairs
