Abstract: A new genus and species, Gumuia zyzzata is found in the Posonchong Formation of the Lower Devonian (Siegenian) from Wenshan district of Yunnan, China. It has both lateral and terminal sporangia. Successive sporangia develop on alternate sides of short axes near the hases of preceding sporangia, producing a zigzag fertile organization. The author supposes that it is a sympodium Opposite sporangia are suppositionally referred to the result from condensation of the axis between alternate sporangia. The new plant is tentatively referred to a putative zosterophyll.
Key words: Lower Devonian, Siegenian, Gumuia gen. nov., Sympodium
