I described D. Woodii as distinct because of its Tinlikeness to my Mindanao 
specimen; but T^hun-'fi Negros plant is intermediate, and Cuming's from Leyte, 
which I have but lately received, is almost exactly like the Mindoro specimens.

These specimens fit Presl's figure so exactly, and the form of the frond is so 
characteristic that I can not doubt their specific identity. Small fronds have 
even the lowest pinnse not quite pinnate. The rhizome is oblique, and the base 
of the stipe black, clothed when young with sparse, broad dailv brown paleae. 
The nearest relative is A. Whitfordi. The texture ia thinly coriaceous.

Nearly related to the preceding, from which, judging by collections up to this 
time, it differs always and very conspicuously in the form of the frond.
