longitudinal row of deciduous "hair-leaves '， along the median line on 

 the dorsal side, especially visible in young stichidia. The articulations 

 being- distinctly seen through the outer coating of the branches, giving 

 them the appearence of being articulated, which whea dried seems 

 -somewhat transversely wrinkled. 



Procarps are transformed from "hair-leaves" situated along the 

 median line on the dorsal side of fertile brahchlets, which either arise 

 from the margins or proliferates from the surface of segments bearing 

 them, and as consequence, fertile branchlets become curved in circinate 

 manner. Unfertilized procarps later develope into stunted nipple-like 

 ramelli, and, many aggregating together, ramelli of cystocarpic frond 

 ' appear curled. Cystocarps are globular with a sunken terminal pore, 

 situated on the ultimate pinnulae or pinnellae, which appear like 

 pedicel. Tctrasporangia are arrang'ed in double rows in the Ijranch- 

 lets transformed into sdchidial organs, which form pinnellae of much 

 branched ultimate segment arising from margins or proliferating 

 from the ventral surface and more or less rolled up into ball-like 

 masses. Substance somewhat fleshy membranous and the plant does 

 not adhere to paper in drying. Colour vinoso-castaneous becoming" 

 darker in drying.
