plerumque superantibus ad furcaturam pedicelloque unico medium versus 2-bracteatis, bracteis ovatis acutis scariosis albidis, petalis 5 bipartitis calycem æquantibus interdum eo brevioribus v. nullis filamentisque ima basi dilatatis fere hypogynis, stylis 3.—Hook. fil. in Icon. Plant. vol. vii. t. 680.

Hab. Lord Auckland's and Campbell's Islands; common on the low grounds, especially in the woods, and near the sea.

Caules tetragoni, e basi valde ramosi, filiformes, 3–5 unc. longi. Folia carnosula, 3–5 lin. longa, obovata seu rhomboidea, hinc inde, siccitate, minute tuberculata. Petioli 1–3 lin. longi, latiusculi. Pedunculi folio plerumque longiores, solitarii, raro uniflori, bifidi seu trifidi; ramis inæqualibus. Petala sæpe O.

In many respects this agrees with the S. uliginosa, Murr., and more particularly in the size and arrangement of the inflorescence, but the stems are always decumbent, the leaves all petiolate, very patent or recurved, and not at all broader or ovate at the base; their callous apices are common to both species. The peduncles generally bear two pedicels, which have a pair of bracts at the base, and a pair on one of the pedicels, whereas in S. uliginosa the peduncle is trichotomously divided, with the intermediate pedicel only destitute of bracts. The styles seem to be constantly three, and the stamens and petals are less decidedly perigynous than in the latter plant. In form the leaves resemble those of S. media, With., but the inflorescence is very different, and the stem wants the alternate line of hairs.


2. Stellaria media, With.Engl. Bot. t. 537.DeC. Prodr. vol. i. p. 396.Alsine, L.

Hab. Lord Auckland's Islands; covering the tomb of a French sailor, and growing along with Poa annua, L.: undoubtedly introduced. A straggling, very common European form of the plant, still retaining all its characters.


IV.DROSERACEÆ, DeC.

1. Drosera (sp.) ?

Hab. Lord Auckland's group; on the hills.—Of this I only once met with a solitary specimen, scarcely in flower, resembling a good deal the D. uniflora, Willd., of Tierra del Fuego; but it was lost among the many botanical rarities brought down to the ship on that day, so that I am only able to record the fact of a species of the genus growing on the island.



V.GERANIACEÆ, DeC.

1. Geranium microphyllum, Hook. fil.; pusillum, adpresse pubescens, caulibus adscendentibus, foliis omnibus longe petiolatis orbiculari-reniformibus 5–7-lobatis, lobis trifidis subtus discoloribus, pedunculis lateralibus solitariis v. binis elongatis unifloris supra medium bibracteolatis, petalis (albis) obovato-cuneatis integris v. retusis, glandulis ad basin staminum fere obsoletis, filamentis ciliatis, stylis brevibus, ovario piloso. (Tab. V.)

Hab. Lord Auckland's group; in boggy places, alt. 1000 feet.

Radix perennis, multiceps, ad collum squamosa; squamis vaginantibus, ovatis, membranaceis, fuscis, nitidis. Caules ex eadem radice 3–4, 3–5 unc. longi, nudiusculi, decumbentes, deinde adscendentes, parce pilosi, crassitie pennæ passerinæ, internodiis remotis. Folia radicalia longissime petiolata, ⅓ unc. lata, supra, et subtus (præcipue ad nervos) adpresse pilosa; lobis lato-cuneatis, obtusis, 3-fidis, segmentis latis acutis; læte viridia, subtus fusco-purpurea. Petioli graciles, filiformes, 2 unc. longi, basi stipulis vaginati, inferne
