198 DIAGNOSIS OF TWO NEW CHINESE FERNS. 



In rupe calcarea ad Pik lok, secus fl. North River, circ. 175 mill, 

 pass, a Cantone, sub fine Octobris a. 1874, coll. Rev. R. H. Graves, 

 M.D. (Herb, propr., n. 18831.) 



The frond-segments of this pretty and interesting little Fern, of 

 which I have seen but three specimens— one growing, the ^others dried 

 — have a singularly close resemblance to those of the Japanese A. 

 monocUamys, Eaton, which, however, has tripinnatisect fronds, the 

 segments coriaceous and conspicuously toothed, and the veins opaque 

 when held to the light. In my specimens, too, from both Yeitch and 

 Maximowicz, the revolute indusioid margin is far larger and deeper 

 than represented in Sir W. Hooker's plate. (Second century of Ferns, 

 t. 50.) The present species, which is very distinct, will take its place, 

 according to Mr. Baker's arrangement, next A. capillus-Junonis, Rupr., 

 the only other one of the Radicantes group with non-dimidiate seg- 

 ments.

This neat Fern, which dries of the most vivid grass-green, belongs 

 to the ^ ^ Foli/stichoidecBy neiYis liberis, indusio reniformi," of Mette- 

 nius's elaborate classification, and is certainly nearer A. cemulum, 

 Sw., than any other species known to me. It is, however, smaller 

 and more delicate, more deltoid in outline, much more sparsely pale- 

 aceous, and with quite glandless indusia. The restriction of the sori 

 to the apices of the upper segments (somewhat as in A. aiiicijiorum^ 

 Wall.), gives it a peculiar appearance, by which it would be easily 

 recognised. I have not seen Miquel's A. siihtripinnatum {^NcpTiro- 

 dium cliinense^ Raker, olim), which Mr. Baker says is very near A. 

 glahrum, Mett. Of the latter I have a b eautiful specimen from Dr. 

 Hillebrand, and it is unquestionably of less proximate affinity to the 

 one now described than is the European and Madeiran plant next 

 which I would range it.
