intermedio producto apice subdilatato obtuso incrassato nudiusculo, sepalis lateralibus linearibus ultra medium incrassatis apice obtusis carnosis marginibus inflexis, petalis ovatis obtusis sepalis ½ brevioribus, spica triflora, scapo fobato.
Hab. Strait of Magalhaens; Elizabeth Island, C. Darwin, Esq.
Planta 1-1½ pedalis. Folia basi longe vaginantia; lamina ovato-lanceolata, sub-recurva. Bracteæ ovato-lanceolatæ, acuminatæ, membranaceæ, concavse. Flores erecti, majusculi, speciosi. Sepala oblongo-lanceolata, omnino nuda, superiore obtuso, lateralibus linearibus, supra medium siccitate nigrescentibus, omnia petalaque venosa et transversim venulosa. Labellum coriaceum, recurvum, marginibus involutis, petalis æquilongum. Columna petalis paulo brevior, arcuata.
A perfectly distinct and very handsome species, confined in its habitat to that eastern portion of the Straits of Magalhaens, where, as Mr. Darwin remarks, the Floras of Fuegia and Patagonia are blended.
2. ASARCA, Poepp.
1. Asarca Commersonii, Lindley, Gen. et Sp. Orchid, p. 405, sub Chloræa.
Hab. Strait of Magalhaens, Commerson; Falkland Islands (Western Island ?) ; Mr. Wright, Mr. Chartres.
Brongniart's description and figure are very characteristic of the Falkland Island specimens of this plant, which is quite distinct from the following. I have seen no Magellanie or Fuegian individuals, Capt. King's Port Famine Chloræa or Asarca being a totally different species. Mr. Wright and Mr. Chartres having gathered it in the Western of the two Falkland Islands, and no other collectors having met with it in the Eastern, I am inclined to consider this plant as one of the Fuegian species which has not spread to the eastern parts of the group, as is the case with the Veronica elliptica.
2. Asarca odoratissima, Poepp., Nov. Gen. et Sp. Plant. Per. et Chil. vol. ii. p. 13. t. 118. Lindley, Gen. et Sp. Orchid. p. 407.
Hab. Falkland Islands (Western Island?), Mr. Wright.
Mr. Wright's specimen of a spike of this plant, preserved in spirits, entirely accords with the figure of Poeppig.
3. Asarca (?) Kingii, Hook, fil.; labello breviter unguiculato oblongo obtuso indiviso integerrimo nudo membranaceo nervis mediis vix incrassatis, sepalis lateralibus lanceolatis acuminatis apicibus simplicibus. petalis oblongo-obovatis obtusis sepalis labelloque paulo brevioribus, spica 6-8-flora.
Hab. Strait of Magalhaens; woods of Port Famine, Capt. King.
Herba pedalis. Folia radicaba 6-unicialia, lanceolata, acuminata. Scapus foliatus. Spica 2—4 unc. longa. Bracteæ ovato-lanceolatæ, acuminatæ, membranaceæ, concavæ. Flores pro genere parvi, flavi. Sepala vix ½ unc. longa, membranacea, venosa, lanceolata, lateralibus basi angustioribus. Petala sepalis paulo breviora. Labellum sepalis æquilongum, omnino indivisum. Columna brevissima.
The short column has induced me to refer this very distinct plant to the genus Asarca, for in a dried state it is almost impossible to determine whether the petals are patent or conniving.
