 STATIONS OF, AND REMAKKS ON, SOME PLYMOUTH PLANTS. 241

Saltash, in the same county, where it was first fouiifl by my friend Mr. Holmes, it is associated with Ornithognlum umhellatum ; and in an orchard near Bnrrington House, Weston Peverell, Devon, it appears witii Nar- cissus bifiorus and a semi-double form of N. poeticiis.

Herheris vuJffaris, L. Mostly in hedgerows near gardens or by houses, but I consider this shrub indigenous in a few spots, as by a creek from St. John's " Lake," Cornwall, whence I have previously recorded it. It may be wild, also, in a hedgerow between Widey and Egg Buckland vicarage, where it extends for about two or three yards ; there is also a single bush on the side of a hedgebank by a field above the valley to the west of Egg Buckland church.

Papaver dubium, L. The common representative of this about Ply- month seems to be P. Lamottei, Bor. ; but, if Professor Babington's character of the "sap becoming dark yellow in the air" be decisive to mark P. Lecoqii, Lamotte, we have the latter also, as the sap of a Poppy now growing at Lipson has unquestionably this property, unlike that of all the other long-headed Poppies that 1 have tried. I cannot, however, find any other g0')d mark of distinction between this Lipson plant and the others, although in it the contraction of the capsule above the torus seems rather greater than in those of them with which I have com- pared it.

Hypericum bfeficHiii, Boiss. ; II. undalatum, Schousb. This occurs rather plentifully in boggy spots surrounded by copse-wood at Warleigh, about five miles from Plymouth. Another Devonian station, where I first met with it last year, is the banks of a small tributary of the Yealm, on the southern border of Dartmoor; but there it grows only sparingly,

iieranium Robertidnum, b. purpnreum, Forst. (Lond. Cat. ed. 6). Growing abundantly from between stones against a bank at Holes Hole, in the parish of Beer Ferris^by the side of the (at that spot) tidal Tamar, June, 1871. At a distance this looks almost intermediate between typi- cal Robertianum and G. lucidum, from its small flowers, vividly-coloured stems, and nearly glabrous condition.

Medicago deidicnlata, Willd. Not general even on the coast, but there I consider it indigenous. Plentiful in grassy spots about a clitf at Port Wrincle, Whitsand Bay, Cornwall, May, 1871; also on a bank on the Devon side of the Tamar at Holes Hole, growing with Salvia verbenaca, June, 1871.

Trif/otiella ornithopodloidcs, De Cand. This occurs in too many locali- ties about Plymouth to be considered rare, though its maritime tendencies render it local. Noticed this year (1871) at the following unrecorded stations : — Crabtree, Devon ; Port Wrincle and TrevoUard, Cornwall, — at the last place associated with Mwnchia erecta, Trifolinm subterraneuni, and Ornithopas perpusillus, species that it often grows with.

Alcheiiiilla vulgaris, L. V>y a stream in a ])asture ai)ove the Erme valley, opposite Lukesland, near Ivybridge. This is rare. It occurs mostly in elevated pastures on the borders of Dartmoor, as in the case just named ; occasionally, however, it is found in low damp situatioijs, as in the Tavy valley and near Blaxton.

Pi/rus torminalis, Ehrh. A splendid example of this, a tree at a rough cakndatiou between 30 and 40 ft. high, with a base clear of branches for about 6 feet from the ground, and a few inches from its sur- face 4 ft. in circumfi rcnce, grows in Warleigh Wood, near tiu; hci'onry ;
