Type: UG-1249

Category: Pteridophyta

Taxonomical identification: cf. Ctenitis / Lastreopsis sp.

First publication: Gelorini, V., Verbeken, A., van Geel, B., Cocqyt, C. and Vershuren, D. (2011) Modern non-pollen palynomorphs from East African lake sediments. Review of Palaeobotany and Palynology 164, 143–173

Other publication/s: Tryon, A.F. and Lugardon, B. (1990) Spores of the Pteridophyta. Surface, wall structure, and diversity based on Electron Microscope Studies. Springer-Verlag, New York

Description: Spores bean-shaped, yellow to brown, 33 × 23 μm, surface covered with coarse and irregularly distributed echinae, varying in size but up to 5 μm tall. This spore strongly resembles both Ctenitis and Lastreopsis, which besides similar spore morphology have similar articulated trichomes on the leaves (Tryon and Lugardon, 1990).

(Sub-) Fossil occurence: No information

Co-occurence: No information

Modern occurence: Ctenitis is widespread in tropical and south-temperate regions, such as Venezuela, Argentina and tropical Africa, and scattered in north-warm temperate regions of Asia, such as Ceylon. It usually occurs in mesic to wet forests. Lastreopsis has nearly the distribution range, and occurs in tropical/subtropical forests and moist lowlands (Tryon and Lugardon, 1990).

Palaeoenvironmental indication: No information
