casual. Several plants there. It o;rew with other casuals, and I have no Jimcus out of a flower-bed to record yet in this list.

Luzula campestris, L. " Hyde Park, Merrett, 1666." — PI. of M.

Butomns umbellatus, L. " Bavswater canal in Kensington Gardens. Herb. Goodger and Eozea, 1817."— Fl. of M.

Lemna polyrrUza, L. " Serpentine, Herb. Devon Institution, Exeter." — Fl. of M.

Potamogeton perfoUatiis, L. " Ornamental basins at head of Serpen- tine."— Fl. of M.

P. crispus, L. Octagon pond abundant, and Serpentine, but less so in the latter. " Ornamental basins at head of Serpentine." — Fl. of M.

P. obtusifoUus, Koch. " In the great circular pond opposite Kensing- ton Palace, Herb. Hardwicke, 1840-1855."— Fl. of M.

P. pusillus, L. Many tufts of this may be found by taking a boat anywhere north of the Serpentine Bridge, and from thence to the foun- tains.

P. pect'matus, L. (Syme, E. B.). Gathered several times in situ from a boat between the Serpentine Bridge and the fountains, but not so abun- dant this year as either P. pusillus or Zannichellia there. This is cui'ious, as I find no previous note for either of these, while P. pectlnatus is well known as a Serpentine plant from early times. I see by Fl. of M. that I also got it from the octagon pond in some year anterior to 1869. The following notes are from the ' Flora of Middlesex ': — " Serpentine River, Hyde Park, Hudson's 'Flora Anglica,' 1762. The P. zosteraceus (Bab. Man. eds. 1, 2) of the Serpentine, Hyde Park, Dr. J. A. Power, was a form of pectinatus. The locality was omitted in subsequent editions, when the name was changed to P.fiahellatus, nor is it (the locality) given in a list by Mr. Babington of localities for the latter plant in Phyt. iv. 1160." I only see in my specimens ordinary pectinatus.

Zantiichellia palustris, L. Octagon pond and Serpentine common. Can be easily gathered floating on the margin of either. This plant fruits nicely here, and is eu-palnstris and not Z. pedicillata, Fries. If the botanist takes a boat, he will find great quantities growing between the bridge and fountains nearly all the way.

Garex muricata, L. P., in the strip north of the Magazine one plant, and a fair quantity of the plant just across the Eing Eoad due west of the Magazine. " Hyde Park, Mr. Groult. Notes by Sir E. Smith in B. M. on the original drawings for E. B., 1790-1814, and Kew Herb." — Fl. of M.

C. ovalis, Good. " Kensington Gardens, E. B." — Fl. of M.

C. flava, L. "Hyde Park, 1817, Herb. Goodger and Eozea." — Fl. of M.

C. hii-ta, L. P., in the strip north of the Magazine, and again be- tween it and the " Humane Society, across the road a good many plants."

Phalaris arundinacea, L. "Serpentine, 1813, Herb. Devonian Insti- tution, Exeter." — Fl. of M.

Anthoxanthum odoratum, L. G., casual, in some sown ground opposite the Alljert Hall. I have not seen it in the genuine Park turf. Seems a grass impatient of smoke.

Plileum pratense, L. G. and P., plentiful in much of the open turf of the Park.

Alopecurus pratensis, L. G. and P., a component of the genuine Park turf; common.
