CHEILANTHES -contmued, 
substance of a rusty-brown colour. The sori are disposed 
in a single row and are in some degree hidden in the axis 
of the reflexed margin of each segment, where they are 
covered by a narrow and continuous indusium. 
C. viscida. 
A very elegant little North American greenhouse 
species, known as the Sticky Lip Fern — a characteristic 
that has given rise to the specific name. Its fronds, Sin. to 
6in. long, narrow-oblong in outline, and bipinnate, are 
borne on wiry, dark brown, tufted stalks 3in. to 5in. long, 
chaffy at the base, but shining in their upper part ; they 
are of a soft, papery texture, minutely glandular, every- 
where sticky, and furnished with from imxv to six pairs of 
nearly stalkless leaflets Jin. long, divided into conspicu- 
ously toothed segments. The sori are disposed from one to 
three to each segment, where they are covered by curiously- 
recurved, minute, herbaceous teeth.

gramme (Mountain Parsley Fern, or liock Brake) 
is composed of a solitary, but distinct and very 
pretty, species, of British or European origin, and of 
only two varieties— one from Northern India, and 
another, a North American form. 
The Mountain Parsley Fern, so named on 
account of its great resemblance to the typical 
Parsley, is one of the prettiest of all our native 
Ferns. It is also one of the very few which, under 
cultivation, have retained their characters perfectly' 
constant ; for, notwithstanding the enormous quanti- 
ties grown under various conditions, no deviation 
from the species worthy of record h as as yet been 
noticed in this country. It is essentially a deciduous 
plant, losing its fronds about the end of October 
and starting into growth again about the beginning 
of May. Its fertile fronds, considerably longer than 
the others and produced as a second crop of foliage 
later in the season, are greatly appreciated for 
bouquets and button-holes. Their spores ripen and
