 illustrations of Tw^binarla irialata var. capensis KiJïz. in Tab.

Remark on the species and the forma: The present species was 

 described by Haiivey under the genus Oijstophyllum from the 

 material collected by Charles AVkight at Shimoda and Hako- 

 date. Since that time no one has given any further information 

 respecting the plant except that De Toni rej^eated the original 

 diagnosis in his works above cited. Harvey's specimen was 

 sterile: and as the species was established on incomplete dried 

 specimens there are some points misrepresented in tlie original 

 diagnosis. The foUow^ing remarks may not be unnecessary for a 

 full knowledge of the species. 



The root is a small holdfast, with the rhizincs robust and 

 cylindrical, ca. 1 mm. in diameter. Frequently some of the 

 rhizine elongate horizontally like a ytolon, giving off several 

 minute processes from the under sides.
