like a casual, in such company), Setaria viridis , and two or three 
obvious aliens; and M. nicceensis more plentiful than the others, 
developing in one case to a height of three feet or more. — E. F. 
Linton. Also sent by the Rev. W. R. Linton. 
Tilia platyphyllos , Scop. High Tor, Matlock, Derbyshire, August, 
1893. — J. H. A. Steuart. “Correct.” — G. Nicholson. 
Medicago lupulina , L. A sericeous form from calcareous and 
greensand cliffs, Folkestone, E. Kent. July-September, 1893. This 
silky pubescent state of a common plant is very strikingly observed 
at Folkestone on the undercliff and elsewhere, the plant in some states 
being dwarfed and rigid and quite white with pubescence, in other 
larger specimens intermediate between that and the usual form. At 
first, till I saw the fructifications, I considered it quite another species. 
— J. Cosmo Melvill. 
Lathyrus hirsutus, L. Near Fordingbridge, S. Hants, 3rd July, 
1893. Well established in a locality which was not entirely free from 
suspicion, but where it would seem to have grown for several years, 
the ground not being in cultivation. Why should it not be native ? 
Mr. Townsend records its occurrence, though he gives it merely as a 
casual, in the ‘Hants Flora.’ A plant or two was discovered this year 
in another locality by Mr. Alfred Hudson, near Christ Church ; in 
my Fordingbridge station it was plentiful, and very fine, some of the 
larger plants furnishing four or five good specimens. — E. F. Linton. 
Lathyrus . Railway bank (one patch), Hill Wootton, Warwick- 
shire, September, 1893. — H. Bromwich. L. tuberosus , L. — J. G. 
Rubus. The work of the Rubi Referee would be greatly lightened, 
and the satisfactoriness of his determinations and suggestions pro- 
portionately increased, if the members would take pains to send only 
good and representative specimens , and to place them always on papers 
stout enough and large enough to bear them safely. Far too often he 
has only broken scraps of badly selected pieces to judge from ; and 
then he must choose between giving no opinion and making what is 
only too likely to prove a misleading guess. Both panicles and stem 
pieces should be well developed, and are most satisfactory when fairly 
average representatives of the plant sent. There is, of course, least 
room left for uncertainty when panicles show both flower and fruit, 
and stem pieces mature leaves from near the middle of the shoot. 
Other less satisfactory pieces in additioii may sometimes help a referee; 
but if in any case a member can feel justified in sending only such 
pieces, he should at least press them carefully and supply them in 
extra quantity. — W. M. Rogers. 
R. ammobius , Focke. A very few plants in one spot only, in a 
thicket by the lake in Castlewellan Park, Co. Down, 4th August, 
1893; and previously in same place by Stewart and Praeger, 1891. 
I could not find it elsewhere in the grounds, and this is the only 
Irish station known. — S. A. Stewart. “ R. suberectus ! ” — Dr. Focke. 
R. sulcatus, Vest. Dullar Wood, Dorset, May to August, 1893. — 
R. P. Murray. Rightly named no doubt, though too weak (especially 
in stem pieces) to be characteristic. — W. M. R.
