Occasional Notes. 315 
Pinnae patent, 24 to 30 to a side, crowded, 1^ inches apart, the face trans- 
verse with the rachis, very shortly petiolate, or quite sessile, 8-15 inches 
long, 1^-2 inches wide, the base subcuneate, the apex acute, margin entire 
undulate, cartilaginous-edged. Texture sub-coriaceous. Colour pale 
glossy green, pellucid. Venation translucent, areolae very fine, oblong, 
directed to the margin. Fertile fronds quite erect, much taller, on 
stouter and longer stipites. Corpuscular covering of the sporangia 
pruinose, at length becoming darker, the segregates sausage shaped, 
pale and translucent; (much larger than those of the next species). — 
Very abundant in marshes of the coast region and on 
the banks of the estuaries and tidal reaches of the river. 
A very fine robust plant, conspicuously marked by its 
large size, crowded rather undulate pinnae, and plumose 
habit — the fertile fronds rigidly ere<5t in the centre and 
the shorter sterile ones spreading around them. The 
former are one-third to twice as high as the latter, and their 
stems nearly twice the length and thickness. The aver- 
age number of leaflets are about the same in both, viz. 
thirty. Occasionally two or three of the lower pinnae of 
the fertile fronds are barren but usually the fronds are 
fertile throughout. 
** Fronds all of one kind. 
Chrysodium aureum> Fee. — Rootstock stout, erect several inches in dia- 
meter, clothed with spathulate-oblong blunt membranous dark-centred 
and scariose-edged scales, that are i£ inch long and 3 lines wide. Sti- 
pites casspitose, rather flexuose, erect, about 2 feet long, smooth, hard 
and ligneous, fths to \ an inch thick, flatfish and channeled on the facei 
with two or three alternate pair of black indurated spinescent spurs, and 
impressed and with a green band down the sides. Fronds 4 feet long. 
Pinnae distant 3-6 inches, 8-10 inches long, i£-i£ inches wide, about 
12 in number, the lower ones most distant and occasionally a little 
reduced, obtuse or emarginate-mucronate at the apex, the margin en- 
tire, cartilaginous and sub-revolute edged, the base cuneate, with a pe- 
tiole 1 inch long, black and indurated in the axil which forms an acute 
angle with the rachis, the two sub-erect rows of pinnae converging for- 
ward rather than spreading laterally. Rachis comparatively slender,
