99. FILICES. 
N. 154. C. fragilis Roth. — Cltistcrs more marginal than in the 
preceding species, ultimately confluent. Pinnae of young fronds 
reflexed. In well-grown plants the pinnse are suddenly widened 
to their full extent just above their naiTow staDdike base. 
Sporules warted. — C. Dickieana (Sim, S. 22.), which has over- 
lapping pinnae, broad blunt pinnules, and scattered clusters, is 
a form of this plant foimd m a damp cave near Aberdeen.^ — 
Rocks and walls. Breadalbane Mountains and Cumberland. 
P. VII. E. S. 
[ C. alpina (Desv.) ; frond lanceolate bipinnate, pinnse ovate, 
pinnules ovate deeply pinnatifid with broadly and shortly linear 
segments partly cloven and slightly toothed at the end. — E. B. 
163. — Fronds very much divided, but compact and close. — On a 
wall at Low Leyton, Essex. P. VII.] E. 
3. C. mo)ituna (Link) ; fi-onds triangular tripinnate, pinnae and 
pinnules spreading, lobes pinnatifid with linear notched segments. 
— S. 24. — Fronds in shape like those of Poh/podtutn Rohertianum, 
small, short, veiy finely divided. Lower pair of pinnae much the 
largest ; their lower larger than their upper pinnules. Stipe long, 
slender. Rhizome creeping extensively, olack. — Breadalbane and 
Grampian Mountains. P. "VTII. ? S. 
[OnocUa sensib'ilis was found in one spot near Wamngton.] 
Tribe III. Aspleniece. 
7. Athte'itjm Roth. Lady-Fern. 
1. A. Filix-fosm'ina(Ro\\i); frond lanceolate pinnate or pinna- 
tifid, pinnae linear, pinnules linear-oblong deeply serrate or pin- 
natifid. — a. A. convexum (Newm.) ; frond bipinnate, pinnides 
toothed narrowly triangular-lanceolate convex remote not con- 
nected toothed, upper ones minute confluent, clusters ultimately 
confluent. N. 245. A. rhccticum Roth. Pinnules long, narro\v, 
with deflexed edges, inclosing the clusters ; their attachment 
broad ; segments gradually decreasing from the base of pinnule. 
— j3. A. FtlLr-fmmina (Roth) ; frond bipinnate, pinnules pinna- 
tifid oblong-lanceolate bluntish flat remote not connected, seg- 
ments oblong patent with lateral and temiinal sharp teeth. N. 237. 
Fi'ond much divided, dark green. Pinnules much narrowed at 
their base. Clusters distinct. A. latifvliuin (Bab.) is apparently 
only an extreme state of this. — y. A. molk (Roth) ; frond pin- 
nate, pinnules toothed oblong blunt or slightly pointed flat re- 
mote all connected by wing of micbib or lower ones distinct, 
segments ovate bidentate lowest with 3 uppenuost with 1 tooth. 
iV. 245. Frond scarcely more than pinnate, bright green. Pin- 
nules attached by a broad decun-ent base. Clusters distinct, in
