Species A. ascendenti habitu simillima, sed glabrior, foliis eoriaceis, formaque stigmatis staminum fnictusque diversissima.

A species so closely resembling A. ascendents that, even in their native place, the Falkland Islands, where both grow together, it is difficult to discriminate them without examination, when the present may be distinguished particularly by the more coriaceous and less hairy leaflets, the spikes more elongated, and bearing remote glomeruli of flowers, or sometimes branching, by the smooth calyx, broader and shorter stigma, and the form of the ripe fruit. This, with all the preceding species, and the following, differ in the form of the stigma from the remainder, iu which that organ is much more elongated, and in which there is less tendency in the peduncles to bear flowers anywhere but at the apex.

6. AafflNA Magellanica, Vahl; abortu dioica?, caule breviusculo subramoso ascendente, foliis sub-coriaceis parce pilosis subtus subsericeis, foliolis 3-7-jugis late obovato-oblongis obtusis sessilibus superioribus decurrentibus grosse et obtuse crenato-serratis interdum 3-5-fidis, pedicello scapiformi nudo v. rarius unifoliato pubescente, capitals parva post autbesin dilatata, calyce petalisque late oblongo-ovatis pilosis, staminibus eloiigatis filamentis gracilibus, antberis majusculis didymis, stylo subelongato latiusculo plumoso.

Very nearly allied to A. Icevigata, and perhaps not specifically distinct ; the capitula are smaller and never divided, the styles rather longer, the peduncles more hairy, and the whole plant less branched than in that species. The hairy peduncles and broad styles at once distinguish this from A. ascendens.

7. A(LENA (Ancistrum) ovalifolia, R. et P. ; sericeo-pubescens, caule longe repente rainoso, ramis sub-erectis foliosis, foliolis 3-4-jugis ovali-oblongis obtusis ad basin usque crenato-serratis supra glabriusculis subtus birsutis sericeisve, pedunculis scapiformibus pubescentibus fere nudis, capitulis globosis, floribus minimis, calyce pilis elongatis subrigidis dense obtecto, petalis obovato-spatlmlatis dorso sericeis, staminibus plerumque 2 filamentis gracilibus, antheris parvis didymis, stylo gracili, stigmate elongato unilaterali plumoso, fructibus villosis setis 2-3 rarius 4 gracilibus apice glochidiatis armato.

Hab. South Chili, and throughout Fuegia ; Banks and Solander, fyc. Ab A. ascendente, cui proxima, diifert floribus parvis, calycibus dense vestitis, antheris minimis didymis, setis fructus duobus tribusve, et foliobs omnibus oblongis regulariter crenato-serratis. Nearly allied to A. ascendens, but in the flower and fruit totally distinct, as I have proved from the examination of many specimens, gathered at various positions between the Equator itself, where it inhabits a level of 12,000 feet, and Cape Horn.

Difficult of determination as the Acana at first sight appear, I feel quite satisfied that they are possessed of ample though overlooked specific characters. The present species has more fully convinced me of this than any of
