36 STATIONS OF SOME PLYMOUTH RUBI. 
cut leaves, grew some years ago on a bank at the top of Crown Hill, 
Knackersknowle; but works in connection with the new fortifications 
around Plymouth having, since then, made it necessary for the bank 
to be levelled, it was entirely destroyed a few years ago. Mr. Bloxam 
at first regarded it as a variety of fruticosus, W. and N., but now, I 
believe, considers it was the R. laciniatus of Willdenow, and distinct. 
I incline to his first opinion as to its being a variety. 
R. leucostachys, Sm. In waste spots by roadsides. The typical 
plant is easily recognized, but puzzling ones near it often occur. In 
a quarry by the Plymouth and Saltash road ; in a waste spot between 
Knackersknowle and Tamerton Foliott, near the abandoned mine; 
Wombwell, ete. 
R. Salteri ; a. Şalteri, Bab. Man. Brit. Bot. ed. 6. “ Bloxam.” 
Rather frequent in low but open situations. On the right bank of the 
Plym, in a marsh below Crabtree, also on the same side of that river 
near Leigham Lodge; by the Egg Buckland road, near Plym Bridge ; 
under some trees, forming a small grove in one of the marshes between 
the Laira estuary and Plympton St. Mary church ; in a waste spot 
near Newnham, close to the bridge over Tory Brook, and by the lane 
leading up by the latter place out on Crownhill Down; in the vale of 
the Yealm, by the path leading from the village of Cornwood to the 
waterfalls ; by the Plymouth and Yealmpton road, near Brixton, just 
beyond the fourth milestone from Plymouth; between Ivybridge and 
Ermington; a bush on a hedgebank by the Plymouth and ‘Tavistock 
road, between Powisland and the George Hotel, ete. The wavy 
edges of the leaves, and, as Mr. Bloxam observes, “sepals at right 
angles with the flower," give this a peculiar appearance. He has had 
specimens of me from many of the stations named above, and says that 
this plant is quite distinct from his calvatus ; but Professor Babington 
firmly maintains the contrary, for, after examining specimens that I sent 
him from the station near Brixton, he wrote, “I think your Saltert — 
from Brixton is the B. of that plant, viz. calvatus of Bloxam ; certainly 
not the true R. Salteri of the Isle of Wight." 
R. calvatus, Blox. The Rev. A. Cit says that a plant that - 
grows rather plentifully in hedges near Beer Alstone is this. It occurs 
also in a hedge between Roborough and Lopwell, near a house named | 
Axter Gate, but seems to be a local plant. Mr. Baker also has had it 
of me from the former station, and he regards it as the true Salferi, a.
