| Abstract: | Stenochlaenaceae is reported for the first time from Guangxi.The family can be distinguished from other ferns by rhizome creeping or climbing,terete;fronds distant,lamina imparipinnate,strongly dimorphic;sterile pinnae articulate to rachis(apical pinna not articulate),with a gland on each petiole,sharply toothed at margin;fertile pinnae linear;veins anastomosing,forming a single row of areoles along each side of midrib,other veins free;sporangia covering the whole of abaxial surface of fertile pinnae.There is only one species recorded in Guangxi,namely Stenochlaena palustris(Burm.) Bedd.According to the original literature and specimens from Guangxi,the characteristics of this species are described and illustrated. |
