Acrostichum appendicidatum ; frondibus pinnatls, pinnis lanceolatis cre-

rachi alato. 
A. appendiculatum ? Willd. Sp. PL v. 5. p. 114. 
A. viviparum, Hamilton's MSS. 
Root creeping, scaly, throwing out downy fibres. Fronds from six or eight 
inches to three feet in height, the stipes of them being from four inches 
to a foot long, somewhat scaly, the rest is lanceolate, acuminate in its 
outline or circumscription, cut into numerous, simple, rather distantly 
placed pinnse, which are in themselves lanceolate, two or three inches in 
length, subfalcate, obtuse at the extremity, and bluntly crenate at the 
margins, the base truncate, or somewhat wedge-shaped, auricled above ; 
midrib not running through the centre, but nearer to the lower margin 
of the frond ; the extremity somewhat caudate and bulbiferous ; bulbs 
scaly, and becoming new plants. Rachis and upper part of the stipes 
winged. 
Ferlile fronds, in the individuals that have come under my observation, 
longer than the sterile ones, which arise from the same root ; pinnated 
above with elliptical, very obtuse, entire pinnae, much smaller than the 
sterile ones, and covered on the under side with the numerous, brown, 
naked capsules. 
Found at Nabovi, in Eastern Camrupa, in 1801, by Dr 
Buchanan Hamilton, who named it in his MS. A. vivi- 
parum, though fully aware, at the same time, of its affinity 
with the A. appendiculatum of Willdenow. The only 
points of difference, as noticed by the latter author, arc, that 
A, appendiculatum is a smaller plant, and has the fertile pin-
