This differs from the V. bidentata, Hook., not only in the same points, except the ch'rhi, as the last species, but in the few leaflets. The broad leaflets, simple cirrhi and differently shaped stipules, short and erect petioles, well distinguish it from V. Kingii. Though these three plants have much affinity, I consider them distinct; having compared them with extensive suites of the Chilian and Buenos Ayrean species, with none of which they accord. Some of the latter again, are very widely dispersed, and it appears to me probable, that more than one Chilian species is common also to North America, and to the higher mountains of Mexico, Columbia and Peru.

Spitharneeus ad pedalem, siccitate nigricans. Caulis ut videtur erectus, parce ramosus. Folia pro planta magna; stipula magnitudine variae, |— f unc. longse, integerrimse ; petioli stricti, parte infra folium ~ unc. longa, in cirrhum strictum ad apicem ramosum desinentes ; foliola 1-2 unc. longa, integerrima, nervis parallelis 3-5. Pedunculi 6-unciales, erecti. Flores pedicellati, maguitudine L. sylvestris. Calyx brevis, glaberrimus.
I have seen no specimens of this from the Strait of Magalhaens ; those from which the foregoing description is drawn up having been gathered at Cape Fairweather, a few miles northward of Fuegia proper, on the east coast of Patagonia, by Capt. King, in whose collection there exists a third species from the same locality, perhaps only a variety of L. nervosum, Lam. {Hook. Bot. Mag. t. 3987.) The L. Magellanicus is hardly distinguishable from a pro- bably undescribed Peruvian species.
