some years they arc much more plentiful than others. — Andkew 
Brothekston. 
Lotus coriiintlatiis, Linn., var. villosns. Hythe, Kent, July, 1876. 
— J. K. Duthie. So I should name it. — J. T. Boswell. 
“ L. tmuis, Kit.” Upland pasture, Harlow Hill, near Harro- 
gate, M. W. Yorkshire. I met with this plant in the same held, 
July 1, 1870, where it grows plentifully, and seems well-established. 
— Thomas J. Uoggitt. AVe have a Lotus form near Plymouth 
which I believe to be identical with this Kom Mr. Foggitt. Here 
I suspect it to be often an introduction with clover and grass seeds. 
— T. K. A. B. Lotus tmuis from Harrogate ; I have doubts, it is gene- 
rally a long straggling plant, not at all like this. — C. C. Babington. 
Lathyms Apliaca, Linn. — Salcombe, near Sidmouth, S. Devon, 
May 30, 1876. A small form in great abundance in a narrow 
valley near the sea, and on the sea-beach. With it, on the beach, 
was Yida hithynica, Linn., and near it, in the rocky valley, Litho- 
spcnii uui. purpure()-cu;ruleum,luiim.,w\iich had forced its stems through 
dense thickets, and was crowning them with profuse masses of its 
bright purple flowers. — W. Moyle Kogers. 
“ I/runus insititia, Linn.” King’s Caple, Herefordshire, April 6 
and July 3, 1876. “ Prunus doiuestica, Linn.” Hedge, near 
cottage, Sellack, Herefordshire, April 5 and June 2, 1876. — 
Augustin Ley. Considering the large size of leaves and flowers, 
and want of spines on each of these, I think we must refer both 
to doviestica, notwithstanding the hairy leaves of the King’s Caple 
shrub. I say the same of a jilant from Mr. Brotherston, collected 
at Plum-braes, Ednam, Koxburgh, 1876. From observations in 
the neighbourhood of Plymouth, I am led to think a series of 
forms connect doiiiestica and insititia ; indeed, some suppose our 
British doiiiestica (or at least the plant of ‘ E. B.’), to be the 
J'. insititia of the Continental botanists. AVe have a first step 
upwards from the Sloe common about Plymouth, and uii(j[uestion- 
ably mdigenous, which helps to make up the “ insititia’' of British 
botanists. It is, I believe, P. fruticans, AVeihe. I have received a 
specimen from tlie Bev. A. Ley, labelled “ insititia ” on Mr. Baker’s 
authority, and Air. Foggitt has contributed numerous examples, 
also labelled “ Linn.,” from “hedges, Bagby, Thirsk, N.E. 
York.,” which likewise seem to be the same form ; but as they are 
simply flowering specimens, without any fully developed leaves, I 
cannot speak positively concerning them. It is, I think, clear that 
insititia” of British botanists includes at least two or three 
forms. — T. E. A. B. 
Ptuhus incur vatus, Bab. Hedge between Port AVrinkle and St. 
Gennans Beacon, E. Cornwall, August 14, 1876. Border of a 
field, Antony, E. Cornwall, August 2, 1873. Sent to Professor 
Babington, with “ incuiratus” queried. — T. E. A. B. Ihilms incur- 
vatns, Antony and Port AVrinkle. — C. C. Babington. 
P. Koehlcri, «. Hedge near St. Donimick, E. Cornwall, Sep- 
tember 12, 1876. Sent with “ AA^eihe ” queried. — T. E. A. B. 
I think a form of KoeJdcri, a. — C. C. Babington.
