238 2. Deaba Falklandica, Hook. fil. ; caespitosa, incano-pubescens, caule brevissimo foliis rosulatis obovato-spatbulatis obtusis integerrimis, dense vestito, pedunculis plurimis robustis breviusculis pedicellisque patentim substellato-pilosis, siliculis corymbosis pedicellis ter longioribus elliptico-oblongis utrinque sub-obtusis in stylum non attenuatis, stylo brevi valido, valvis concavis stellatim pubescentibus, seminibus plurimis parvis, funiculis brevibus.

Hab. Falkland Islands ; Lieut. Robinson, R.N.

Radix lignosa, descendens, ad apicem fasciciduin rosulatum dense aggregatum foliorum subcoriaceorum gerens. Folia ! uncialia, pubescenti-hirsuta, subtus pilis stellatis conspersa. Pedunculi 1-^—2 unciales, validi, nudi v. ima basi uniibliati. Silicida 3-4 lin. longse, stigmate brevi crasso terminatse.

The most prominent characters of this species are the densely leafy short stem, or more properly cluster of abbreviated stems, which immediately surmounts the root; the short stout scapes, with comparatively large corymbs of pods ; the latter are obtuse at both ends, but not abrupt, and the seeds are small, placed close to the margins of the valves and the opposite series separated by a very broad dissepiment.

3. Deaba funiculosa, Hook. fil. ; glaberrima, caule breviusculo ramoso, ramis foliosis, foliis lineari-lanceolatis interduin oppositis basique subconnatis margine argute eiliato-dentatis, scapis gracilibus ad apicem paucifloris, pedicellis fructiferis brevibus, sibculis liuearibus utrinque obtusis, stigmate bilobo sessili, valvis planiusculis, seminibus plurimis oblongis, funiculis elongatis capillaceis. (Tab. LXXXIX.)

Radix sublignosa. Catdes pluries divisi, ramis £— J unc. longis. Folia erecto-patentia, rigida, |— i- uncialia, basi in petiolum subdilatata. Scapi 2-3 unc. longi, floriferi breves. Flares parvi, 3-5, breviter pedicellati, albidi, inconspicm. Sepala ovata, obtusa. Petala calyce bis longiora, spathulata, ad apicem rotuudata. Staminum fdamentis gracilibus. Ovarium oblongo-ovatum. Silicida foliis subaequiloiiga, linearis, valvis ter quaterve longioribus quam latis, medio obscure uninerviis.

A very peculiar species and resembling the D. oligospermia, Hook., of Arctic America, most in habit, and particularly D. lactea, Adams, a native of Siberia, in the form and eiliation of the leaves ; it has no near ally on the South American continent.

Semina plurima, biseriaba, oblongo-cordata, in rostrum breve producta; testa crassa, subspongiosa, albida. Silicida oblonga, valvis convexis navicularibus, dissepimento nullo. Cotyledones accumbentes. — Genus nidli arete, ajjii/e Eutrernre/o/vwa seminiim dissepimentoque relracto accedens, sed potius Drabse indole silicida et structura embryonis relation.
