Falklands, etc.] This is certainly, in its present state, the most obscure and, except the Pringlea, the most remarkable plant of Kerguelen's Land. I have placed it provisionally amongst Portulaeece, knowing no other order with which it has any equally direct affinity. There is one plant to which it bears, at any rate, a very close resemblance if nothing more, the Pyenophyllum, molle, Eemy (Ann. Sc. Nat., 3rd Ser. vol. v. p. 355. t. 20. f. 2-8), of the Bolivian Ancles ; for a fragment of the original specimen of which (preserved in Herb. Mus. Paris) 1 am indebted to the liberality of M. Decaisne. In Pyenophyllum, however, the leaves are truly opposite and connate, and the capsule three-lobed, if not three-valved.

This highly curious genus, coming from the most interesting island visited by the Antarctic Expedition, will serve to commemorate in some slight degree the important services rendered to Botany by my zealous friend and co-operator, Dr. Lyall, E.N.

Plate CXXII. — Fiy. 1, a leaf; fig. 2, bracteae, peduncle, and fruit ; fig. 3, utriculus removed from the calyx ; fig. 4, vertical section of the same, showing the ripened and abortive seed ; fig. 5, seed and funiculus ; fig. 6, seed, with the testa removed; fig. 7, embryo : — all magnified.

p. 292. Of the Valdivian specimens alluded to as belonging apparently to this species, I have recently examined complete individuals, which prove them to be M. imbricatum, Poepp. The female flowers do not probably differ materially from those of M. punctulatum.

p. 296. In description of Plate CIV. the figures of 9, 10, 11, and 12, referred to as taken from Bridges' Valdivian specimens, belong to M. imbricatum, Poepp.

p. 304. Chiliotrichum handle : — M. Planchon considers this species, together with the C. Kii/gii and C. Darwinii, as referable to the genus Nardopliyllum, DC.

p. 327. Lebetanthus Americanus : — this appears to be a true Prionotes, the placcntation being the same as in the original P. cerintjioides of Tasmania, and the position of the bracteae on the pedicel not affording a generic character. In two undoubted congeners from Tasmania, the ovules are attached to erect basal columns.

Ramus 10-uncialis simplicissimus solum mini notus. Petioli unciales, foliis sequilongi. Flores minimi, dense aggregati.

Described from a solitary specimen in the Herbarium of the Horticultural Society of London, in the absence of any means of comparing it with its congeners in the Herb. Hook., of which the Clienopodiacets are now in the hands of M. Moquin Tandon for examination.

p. 343. Nanodea muscosa : — I am inclined to suspect, from certain circumstances connected with the locality of this plant, that it may be parasitical, like the Tliesium linopliyllum.

p. 359. Luzula, sp. — Of this species I have recently found more complete (hitherto mislaid) specimens in my collection, they may be thus described:—
