This document provides classification and morphological information about the bryophyte genus Pellia. Pellia belongs to the division Bryophytes, order Jungermanniales, and family Pelliaceae. It has a simple, prostrate thallus that is dichotomously branched with a midrib but no scales. Antheridia and archegonia are located on the dorsal surface. The sporophyte develops from the mature archegonium and has a foot, seta, and capsule structure that contains spores and elaters.

2. CLASSIFICATION
 DIVISION: BRYOPHYTES
 ORDER: JUNGERMANNIALES
 FAMILY: PELLIACEAE
 GENUS: PELLIA

3. Jungermaniales divided in two groups
Anacrogynus Acrogynus
Pellia comes in anacrogynus
REASON :- ARCHEGONIA BORN ON THE DORSAL
SURFACE OF THE PROSTRATE SHOOT.
APICAL CELL ARE NOT INVOLVED IN THE
FORMATION OF ARCHEGONIA.

4. MORPHOLOGY
 Simple prostrate thallus.
 Only smooth rhizoids present.
 Dichotomously branched.
 Mid rib but no scales.
 Mucilage hairs on growing tip.
 Green thallus.
 Thin thallus but thick on mid rib.

5. ANATOMY
thalluls contain Parenchymatous cells.
Both side of epidermis present.
Fiberous cells present.
Chloroplast present.
Antheridium on dorsal side hold with stalk cells.

6. Antheridium
 Antheridium present on Dorsal surface
Of thallus.
It is covered with a jacket and hold by
Stalk cells , there are many antheridium in
One antheridia .And antheridia are
Biflegellate ,spiral shaped.

7. Archegonia
Archegonia found in clusters form. Cover with
involucre. Mature archegonia contain to egg.
Before furtilization neck wall is single
layered . After fertilization archegonia
changed into sporophyte capsule and hanging
on air.

8. Sporophyte
Sporphyte is a mature archegonia. Its body
divided in foot, seta and capsule. Foot is a
base and seta is a elongated structure and
capsule is upper cap like structure.
Capsule coverd with calyptra . Inner side of
calyptra here is spores and and elaters are
present (on elatophore).
Spores and elaters are covered with single
layered jacket. After brust of capsule here is
spores are dispersed and persist elatophre
disc.
