QUERIES IN LOCAL TOPOGRAPHICAL BOTANY. 259 
Sound to its appearance in the distant county of Sussex. Probably 
a great part of the kingdom would be too cold to suit it well, but 
this does not supply a sufficient reason for its growing only in two 
widely separated localities on the southern coast. 
The genus (Enanthe adds some remarkable facts of species dis- 
tribution in Devon and Cornwall. The occurrence of (E. pim- 
pmelloides, L., on the Plymouth Hoe, furnished the reason for its 
being accounted Devonian by Watson in Cybele Britannica (iii. 422), 
on faith of specimens sent thence by Mr. F. H. Goulding. Mr. 
Keys, in his Devon and Cornwall Flora, says Mr. Charles Harper 
first directed his (Mr. Keys's) attention to it so long ago as 1847, 
at which time there were several roots; but that in 1852 he 
could only find one. I am glad, however, to say that so recently 
as the spring of last year I noticed six or seven patches ; some of 
the plants having stems in bud among the leaves, though much 
stunted and injured, as might be expected in so much-frequented 
a place. This species is otherwise unknown about Plymouth, 
though "frequent down the main valley of the Teign from 
Christow to Newton Abbot " (Rev. W. Moyle Eogers, Flora Teign 
Basin, p. 14), and found elsewhere in the county by the south-east 
coast. From Plymouth westward we find no record of it until we 
get to the Lizard and Land's End districts, where it reappears. In 
the counties of Devon and Cornwall alone it thus occurs on rocks 
of three or four different formations, notwithstanding its stations 
are so widely separated. A plain proof that species-ranges as they 
come before us at present must have been brought about by 
influences additional to those of soil and climate. 
(Enanthe fistulosa, L., seems rarer than (E. pimpinelloides in 
Devon and Cornwall. Some years ago, through the kindness of a 
friend, I received fresh specimens from Slapton Ley, a large pool 
occasionally connected with the sea between Kingsbridge and 
Dartmouth. I have seen it growing in St. Mary's, Scilly, where it 
was discovered by Mr. Townsend. Its paucity in the extreme 
south-west of England may be partly accounted for by the fact of 
there being comparatively few still waters and stagnant ditches in 
this hilly area. 
In the neighbourhood of Plymouth (E. Lachenalii, Gmelin, is to 
be seen only about some tidal waters and inlets connected with the 
Tamar and Notter estuaries, being absent from the outlets of the 
Plym, Yealm, and Erme. Whether we take a comparatively small
