Komlopteris

The leaves are generally lanceolate to slightly falcate, though some are ovate, and form a pinnate arrangement, and are sometimes bipinnate.

The finding of numerous leaves of Komlopteris in single leaf mat layers suggests that at least some species were deciduous.

[1] However, some authors have suggested that the ovulate reproducive organ Sacculotheca from the Early Jurassic of Hungary, which co-occurs with Komlopteris and shares a similar stomatal pattern, is part of the same plant.

[4] The type species is K. nordenskioeldii, known from the earliest Jurassic (Hettangian) of Sweden,[1] as well as other parts of Europe like Hungary (Mecsek Coal Formation).

[1] Species known from the Late Jurassic include K. khatangiensis from India, K. constricta from the Antarctic Peninsula, and K. purlawaughensis from the Talbragar Fish Bed in NSW, Australia.
