6. A. bulbiferum. A very beautiful and common fern, easil 
recognized in its most highly developed form, by the germinatin: 
bulbs on its pinnules. Fronds bright green, not stiff, 1 — 3 fed 
long, bi-pinnate ; rachis of the pinnae often winged ; pinnuh 
deeply cut. Its varieties are very difficult to define, perhaps tl i 
following are the most remarkable. 
Var. A. Frond pinnate, pinnae pinnatifid, shining, lower pinmi 
gradually diminishing in size ; no bulbs. 
Var. B. laxum. Fronds generally pendulous, pinnules deep! 
divided into segments.

rare. Small bush on the Waimea, Nelson. Banks’ Peninsula. 
In his Flora Zelandiae Dr. Hooker considers this fern

Sir William J. Hooker unites this last with A. Richardi , and coi 
siders the former a distinct species. 
8. A. Richardi. Very rare ; fronds 4 — 6 inches high, rigie 
dark green, tufted, bi-pinnate ; pinnae stalked ; pinnules general! 1 
without stalks, crowded, deeply pinnatifid, with oblong, blunt seg

segments ; veins forked, one to each segment, thickening at th 
end, terminating within the margin. “Southern Island
