THINNFELDIA (Httingshausen). 
Fronds pinnate, segments or pinne oblong, ovate lanceolate, 
decurrent, and confluent at the base, coriaceous ; costa divided 
into many veins, venules and veinlets, before reaching the 
apex; velns emerging ata slight angle, diverging in ascending, 
and often forking, venules or veinlets reaching the margin. 
Stomata in both sides of the lobes. Obs.—The frond is generally 
dichotomous, and is with the leaves of a thick and fleshy 
habit. It belongsin Europe to the lower Lias and Rhaetic 
formations.
