Characteristics |
Lycophyta |
Barinophyton obscurum, B. citrulliforme, Sawdonia, Deheubarthia |
microphyll with a single vascular strand. Sporangia are kidney shaped. Sporangia formed on sporophylls clustered in strobili.Many are epiphytes. |
Pterophyta |
Bolbitis heudelotii · Dryopteris affinis · Asplenium antiquum · Polystichum setiferum · Azolla filiculoides etc. |
Leaves are megaphylls called as fronds.Leaves compounded with a rachis and numerous pinnae. Shows circinate vernation. Stems are rhizomes. Roots are simple, uncomplicated and arise adventitiously along the rhizomes. Sporangia located on Sori. |
Hepatophyta |
Monoclea frosteri |
Commonly known as liverworts. These are small, usually from 2–20 millimeters (0.08–0.8 in) wide with individual plants less than 10 centimetre (4 in) long. Thallus is leaf like structure, flattened and bilaterally symmetrical. Asexual reproduction through fragmentation or gemmae production. Sexual reproduction within the archegonia. Sporophyte not capable of photosynthesis |
Bryophyta |
Funaria, Marchantia, Plagiochasma etc. |
Life cycle dominated by gametophyte stage. Unbranched sporophyte. abscence of true vascular tissue containing lignin. Have rhizoids instead of roots. |
