hi,
The highest division of cryptogammae is pteridophytes. General features of pteridophytes :
The plant body is differentiated into roots, stems, and leaves.They have specialized, conducting tissues for the conduction of water and other substances.They have inconspicuous or less differentiated reproductive organs.They produce naked embryos called spores.
Some examples of pteridophytes are ferns, Marsilea, Equisetum, and Lycopodium.
hope helped..

Subkingdom Cryptogamae➫ Those kingdoms which are Flowerless & Seedless plants.
❱ It's Characteristics are:-═════════════════☟
◉ These are seedless & flowerless plants.
◉ These plants reproduce by producing spores.
◉ Reproductive organs are inconspicuous.
◉ Lower cryptogams don't have true Stem, Roots, Leaves & Vascular system.
➧Subkingdom Cryptogamae divided into three groups:-▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃⤵
❶❫ Thallophyta:- ▬▬▬▬▬▬▬▬▬▬▬☟
①❭ Plants body remains in the form of Undifferentiated.
②❭ Vascular System is Absent.
③❭ Mode of nutrition is Phototrophic & Autotrophic.
④❭ Reproduction is both Sexual & Asexual.
⑤❭ Asexual reproduction takes place by Spore formation.
⑥❭ Fertilization is not followed by Embryo formation.
▶Ex:- Spirogyra, Ulva, Fucus, Volvax & Chara
❷❫ Bryophyta:- ▬▬▬▬▬▬▬▬▬▬▬☟
①❭ Plant body is not differentiated into true roots, steam & leaves.
②❭ Non-vascular plant are not developed.
③❭ Fixation by rhzoids.
④❭ Gametophyte are the main plant.
⑤❭ Sex organs are multicellular.
⑥❭ Water is required for fertilization.
▶Ex:- Funaria & Riccia
❸❫ Pteridophyta:- ▬▬▬▬▬▬▬▬▬▬▬☟
①❭ Plant body is differentiated into true roots, steam & leaves.
②❭ Vascular plant are developed.
③❭ Fixation by roots.
④❭ Sporophyte are the main plant.
⑤❭ They are the first truly Terrestrial & vascular cryptogams.
⑥❭ Water is needed for fertilization.
▶Ex:- Azolla & Dryopteris
