Synopsis

Lepidodendron calamopsoides sp. nov. is described from petrified protostelic stems formerly considered identical with Levicaulis arranensis Beck. The stems range from 2 to 20 mm. diameter and some possess leaf-cushions usually about 10 × 1 mm.

Three specimens are known showing the transition from stem to rooting organs. Secondary xylem has only been seen in the transition region and rooting organs. The latter resemble Calamopsis dubia Solms-Laubach now considered to be part of the closely related Lepidodendron saalfeldense.
