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.

PELLIA LIFE CYCLE
CLASSIFICATION  DIVISION: BRYOPHYTES  ORDER: JUNGERMANNIALES  FAMILY: PELLIACEAE  GENUS: PELLIA
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.
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.
ANATOMY thalluls contain Parenchymatous cells. Both side of epidermis present. Fiberous cells present. Chloroplast present. Antheridium on dorsal side hold with stalk cells.
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.
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.
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.
Thank you
