230 THE FLORA or HYDE park and KENSINGTON GARDENS.
Erysimum cheiranihoides, L. P., has maintained itself as a weed for several years in the tlovver-beds west of the Marble Arch.
Sinapis arue/i/siis, L. G., a weed from the south side of the Gardens ; gathered by the Rev. W. W. Newbould.
Thlaspi arvense, L. Casual in some enclosed newly sown grass west of the Albert Memorial.
Camelina sativa, Cr. " Came up in Kensington Gardens with grass sown for turf, 1834 ; Mag. Nat. Hist. viii. 389. "-^Fl. of M.
Capsella Bursa-pastoris, De Cand. P. & G., everywhere ; a large component of the open turf.
Coronopm Ruell'd, Gaert. G., abundant in the grass west of the fountains. P., here and there not uncommon.
C. didyma, Sm. G., all along in the gravel of the path on the bridge over the Serpentine; continuous for 100 yards. P., a plant under a clump of trees about 200 yards west of the Magazine.
Rtneda Luteola, L. " Wall south side of Hyde Park, 1815. Goodger and Rozea's Herb." — PL of M.
Lychnis Githayo, Lam. G., casual as a weed on the south side of the Gardens ; gathered by the Rev. W. W. Newbould.
Sngina procumliens, L. G., near the well, under the Scotch firs, in the path north of the palace. P., in the strip.
S. apetala, L. (vera). P., a single plant in the strip.
S. ciliata, Pries. P., west of the " Humane Society " towards the Magazine, near an old road which has become grassed over. It grows plentifully and is conspicuous enough. An excellent spot to study the species, as the examples are nicely grown and typical.
Arenaria serpyllifoUu, L. P., in and near an old road now turfed over, west of the " Humane Society."
Stellaria media, With. P. and G., in the open turf wherever it gets a little bare ; common and general.
S. graminea, L. P., in a flower-bed near the old Reservoir. " Ken- sington Gardens, 1845, Morris." — Fl. of M.
Cerastium ylomeratum, Thuill. P., on some bare rubbish-made ground 200 yards north-east of the Magazine. This was a casual, and the ordi- nary form. In the old grassed road west of the " Humane Society." 5 or 6 plants, a dwarf apetalous state ; C. apetalum, Dum. ? " In Hyde Park, Merrett."— Fl. of M.
C. triviale. Link. G. and P., common in the open turf, and in every pathway edge. " Kensington Gardens." — Fl. of M.
Moenchia erecta, Sm. P., " Hyde Park, Dickson's H. S. In the dry part north of the Magazine, 1820, Bennett."— Fl. of M. I believe this still may be re-found in Hyde Park, judging by the nature of the ground in a few likely places where plants apparently of similar situations to Moenchia, often associated with it, and quite as unlikely to endure smoke, still hold their ground. It must be sought early.
Spergularia rubra, Fenzl. P., in the strip, several patches ; one of considerable size near the pathway north from the Magazine. Several plants at the west end of Rotten Row. " Kensington Gardens, 1866." — Fl. of M.
Spergula arvensis,\j. P. and G., casual here and there, sown among Grass seeds in enclosed places.
Malva sylvestris, L. P., a plant in a flower-bed near Prince's Gate, probably casual here.
