Hab. Java, Blume. Khasia, Griffith, and, at elevations of from 1000 to 4000 feet, 

 Hooker fil. and Thomson. — At first sight tlie lower half of the frond appears to be 

 pinnated, bnt it will easily be seen that the pinuaj or segments are united by a 

 narrow wing on the rachis. All the segments are more or less falcate and remote, 

 and their superior base runs up, as it were {sursnm currens, in contradistinction to 

 the term decurrens), so as to join the rounded base of the one above it. The 

 ba.>e of the stipes has very much the character of that of Plagiogyria biserrata, 

 but it is narrower and less carnose than in that si)ecies, which is, however, its 

 nearest ally, as being pinnatifid; but the remote segments, broad sinuses, scarcely 

 serrated margins (except the acuminated apex), will abundantly distinguish it. The 

 stipites are very long and slender, and the old ones singularly brittle externally, 

 for there is a stout stupose thread, which remains entire when the outer sejjarates 

 in tubes. I here find the capsules indistinctly helicogyrate. Mettenius's Pla- 

 giogyria scandens, a plant of Griffith, and from Khasia, appears to have been de- 

 scribed from very imperfect si)ecimens, and I suspect is this plant : if so, it has 

 no indication of being a scandent plant. Indeed, Mettenius does not seem to 

 have known the caudex, for he says, " Truncus . . . .'" — Mr. Moore suggested to 

 me that this plant is the L. adnata of Blume, as far as can be judged from his 

 short character, and I adopt it rather than increase the number of synonyms 

 heedlessly.
