inherited from any known source. 
A. c. mundulum. 
This charmingly pretty and compact-growing variety, of 
garden oiigin, may reaisonably be termed la perfect minia- 
ture, and quite a gem among Adiantums. It forms a very 
elegant little subject, seldom more than 8in. high. Its 
fronds, which are produced in profusion from a densely- 
tufted crown, are tripinnate, triangular, and furnished 
with numerous leafits, which are narrowly wedge-shaped, 
a few of the larger ones among them being three-lobed. The 
sori are roundish, and disposed one in each notch of tJie 
lobes. The fronds are remarkably stiff, of good substance, 
and particularly well adapted for mixing with small flowers. 
This form reproduces itself true from spores. 
A. Cunninghamii. 
Synonymous with A. affine. 
A. curvatum. 
A beautiful and entirely distinct Brazilian stove species.

rhizome, are borne on black, shining stalks. Sin. to 12in. 
long, and are dichotomous. Their leaflets, Sin. to 12in. 
long and about Sin. broad, are furnished witJi leafits nearly 
l^in. long, curved, overlapping, with their superior margin 
and point finely toothed : these pinnules are of a light green 
colour, and are attached to the midrib by a very short foot- 
stalk. The sori are oblong and disposed singly, about seven 
of them on a pinnule. This Fern requires shade and a 
very moderate amount of moisture. 
A. cyclosorum. 
This grand, well-marked, evergreen, stove species, from 
New Guinea, is very effective. Its triangular fronds, which 
are borne on upright, stout, glossy-black stalks, Sin. to 12in. 
long, are three times divided to the midrib, and furnished 
with spreading leaflets. They possess a very feathery ap- 
pearance through their rhomboid leafits, being borne on 
short stalks and set far apart. These leafits are grace- 
fully arched, and of a beautiful bronzy-pink when in a 
young state, whereas when matured they are of a pleasing 
light green. The sori are circular and disposed eight to 
ten round the margin of each pinnule.
