saki in May 1870 and kept in tbe herbarium of the Science College 

 of Tokyo, accords pretty well with the original diagnosis and the 

 photopraph of the authentic specimen of the above mentioned 

 species. The species was rather briefly defined and as no comment 

 on it nor a figure of it has since been given, the following 

 observations on our specimens may not be superfluous. 



The specimen in the herbarium lacks the I'oot, but seems to 

 have been cut oÏÏ quite near the base. The total length of the 

 specimen is about 30 cm. The stems of the principal branches 

 are cylindrical and smooth, gradually tereto-compressed above 

 and subpinnately or vaguely ramose. The leaves on the principal 

 branches, i. e., the fulcrant leaves, are oblongo-spathulate, gener- 

 ally oblique at the base and blunt at the apex ; the ribs are 

 hardly elevated above the surface of the laminœ and appear 

 as obscure dark streaks running longitudinally in the median 

 line. In most cases they reach quite to the apex of the leaf, 

 but sometimes become evanescent above. The leaves on the lower 

 portion of the frond are frosted with a few rows of cryptostoraata, 

 but the upper narrow ones have only a single row of them on each 

 side of the rib ; margins, sparingly dentated, with each tooth 

 subapiculated ; substance of leaves, thin and membranaceous, 

 turning yellowish brown on drying. 



The vesicles are spherical, rounded at the apex and mostly 

 marginated. They are found solitary at the base of each lateral 

 branch. Those found on the upper portion of the fronds are 

 evidently glandulatcd ; but in the second specimen, collected in 

 Kii Prov. by the writer, they were entirely unspotted. The stalks 

 are from a half to a whole length longer than the diameter ot 

 the vesicle, dilatated upward so as to become confluent with the 

 marginal wings, if any, of the vesicle.
