come up in spring, bear fruit more or less, persist more or less, but 
never grow more than one year; while those of H. unilaterale go 
on growing year after year. A great number of the fronds which 
were on the plants when placed in the case went on growing, bore 
fruit at or near the extremity of the fronds that year, grew on again 
and bore fruitlast year, and are doing the same this year (1856), 
so that some fronds are ten inches long, and wide in proportion. 
This is not the effect of cultivation, as the wild plant does exactly 
the same—growing ‘annotinously,’ in fact, exactly as occurs in 
Lycopodium Selago and Bartramia Halleriana, there being no distinct 
marks between the different years’ growth.” 
This species is more extensively distributed than H. tunbridgense, 
though the two plants very frequently occur in company. The pre- 
sent is met with in the south-west of England, and is reported from 
several midland counties ; itis found both in North and South Wales ; 
and in the north of England, especially in the Lake District, it becomes 
plentiful. It is the commoner of the two species in Scotland, occur- 
ring both in the Lowlands and Highlands as far north as Suther- 
. landshire, and extending even to the Northern and Western Isles. 
In Ireland it occurs plentifully, and in all the provinces. In alti- 
tudinal range this plant is found from the coast level to an eleva- 
tion of upwards of 2700 feet, which it attains in the outer Hebrides, 
according to the observations of Dr. Balfour and Mr. Babington.
