1876. Specimens of this plant were forwarded by myself to the 
Eev. A. Bloxam, in 1874, labelled “ li. scahcr, var.” Commenting 
on this, life replied; “ I should call this typical acaher. I find a 
similar plant in Ijeicester shire.” It is a very different plant to 
the form usually labelled JL scaber, having a more open panicle, 
leaves remarkably flat, and stem less hauy and setose. Taking 
this as the type of li. scaber, I should say that it is very rare 
in Warwickshire, as I have only seen it in two or three places at 
Sutton Park. — James Bagnall. 
Rubm BatinaUi, Blox. {R. Bn'misii var. Jkuinalli, Bab.) Hay- 
woods, Warwickshire, v.-c. 38, July, 1876. This iffant I found 
growing abundantly in the above' station in 1874, and then sent it 
to Professor Babington, wuth the provisional name, R. cordatus 
(Bagnall MSS.) Professor Babington, after careful examination 
of the specimens sent, kindly informed me that my plant was not 
the R. cordatus of foreign botanists (I was not before aware that 
the name had been given to a Continental form), and that he con- 
sidered it to be identical with the Ji. BriinisH, Blox. Mr. Briggs, 
also, held the same opinion. The Bev. A. Bloxam, to whom I also 
sent the plant, with Professor Babington’s remarks thereon, and to 
whom I had also sent roots, so that he might watch it in the living 
state, stated that he considered it to be truly distinct from 
R. liritfiisn, as truly distinct as R. thi/rsoideus is from R. discolor ; 
and as my proposed name, R. cordatus, was already appropriated, 
he should name it R. Ba(jncdli, and also called attention to the 
following distinctive characteristics by which it might readily be 
distinguished from R. Jyri(j(/sii, viz., the constantly cordate basal 
and intermediate leaflets, and the elongated petiole of the truly 
cordate terminal leaflets. In a more recent communication, 
October 27, 1876, Professor Babington says: “I cannot see any 
material difference between your cordatus and the true ‘ Brbigsii 
the terminal petiole is long in both of them and rather variable. 
It may, perhaps, be a well-marked form to be known by the 
cordate intermediate leaflets, as Bloxam remarks. As such a form, 
it may bear the name he gives to it, R. BaffnalliB The plant 
is still abundant in the above station, and seems to have a more 
rami)ant habit of growth than R. BriggsU, if I may judge of this 
plant by the shoots I have seen growing in Mr. Bloxain’s garden, 
and that plant, if I remember rightly, has always ternate, closely- 
imbricatc leaflets, whilst in the R. BagnaUi the 5-nate leaf is more 
frequent than the 8-nate, and the basal leaflets have a very much 
more decided tendency to be turned right away back, so that their 
apices always point towards the base of the petiole. — James 
Bagnall. Although R. Briggsii has normally ternate leaflets, .yet 
this is not invariably the case, as they are sometimes quinate- 
pedatc. The original specimens I collected from a very dry, stony 
spot ; and to the nature of the habitat are due, as I believe, some 
of the slight differences between them and Mr. Bagnall’s Harwoods 
specimens, coming from a different situation. I have recently 
found what I consider R. Briggsii in a second locality, near 
Plymouth, where its general appearance is nearer that of the
