310 CHARACTERS OF BRITISH PLANTS. 
whose stones are so abundantly swallowed and again disgorg- 
‘ed by thrushes and other birds. 
Fragaria Vesca (Linn.)—* The close-pressed hairs of the 
flower-stalks become gradually more and more spread out as 
the fruit ripens." (J. E. Bowman, MSS.) 
Epilobium angustifolium (Linn.)—The long-fruited form, 
the E. macrocarpum of Stephens, is the Linnean type of the 
species, and far the most common in Britain. The variety 
called E. brachycarpum by Leighton, is the garden form, and 
rare in a wild state. They pass into each other by interme- 
diate forms. I have seen the long and short fruit on the same 
plant, though probably this is a rare coincidence. 
Epilobium alpinum (Linn.) and E. alsinifolium (Vill.)—In 
the Manual, the stoloniferous “root” of the former is con- 
trasted against the stoloniferous “ stem” of the latter. But 
E. alpinum certainly throws out rooting branches or shoots 
from the base of the stem, both above and below the surface 
of the ground. From their mode of growth, the stems are 
often much buried in mud or moss; and it is by no means 
easy in such cases to say which is root and which is stem. 
Their affinity is more with E. tetragonum than with E. mon- 
tanum; and mountain specimens of the former have some- 
times been named E.alsinifolium, by botanists familiar enough 
with the plants. Even in Surrey, I have gathered specimens 
of E. tetragonum which resembled E. alpinum in bearing a 
solitary and drooping bud at the end of a very short stem. 
Callitriche pedunculata, var. terrestris.—This variety is cor- 
rectly placed in the last edition of the British Flora. I can- 
not have expressed my meaning clearly, or Mr. Babington 
would not have referred it to C. platycarpa. If I really know 
this latter plant, it appears scarce distinct from C. verna. 
The locality of ** ditehes near London" probably belongs to 
C. pedunculata, which has so frequently been mistaken for 
C. autumnalis. 
Ginanthe pimpinelloides (Linn. ?) and Œ. peucedanifolia 
(Poll)—Mr. Babington asks whether there is nota third
