This appears to be Brown's S. lineare and JIÜRer’s S. gratalalormn of Port Adelaide in Herb. Bentham, and
perhaps o f Port PhiRip, though the specimen ot the latter in Herb. Hook, is a veiy much branched, robust plant, with
pubescent branches. Neither Miilier's A delaide specimens (in Herb. Bentham). nor the Tasmanian ones, are as slender
as that desenhed by Brown. The leaves are both entire and somewhat piimalifidly cut in the Port PliOlip specimen.
and the repluni seems rather stronger than in the Tasmanian ones. As I have only one good example o f Gmin's
plant, some allowance must be made for this description. aU these Orueiferæ being excessively variable. especiaHy

I t is flifficidt to suppose that this plant is w ild in Tasmania and Australia, seeing that its European and Asiatic
range is quite normal, and that it does not inhabit any part o f the American or Australian continents, except ivliere
civilization lias extended.— A slender, annual or perennial, procumbent, diffusely-branched, glabrous herb, with few
leaves, and slender, often flexuous branches, a span long, nmning out into long fruiting racemes. Leaves 1 inch long,
spathidate, lanceolate, entke, sinuate o f pinnatifid. Flowers minute; p e ta ls white. Capsules small, -Jg- inch long,
on slender spreading pedicels i mch long, terminated by very short straight styles. Valves obovate-oblong, reticulate,
boat-shaped. Seeds few.

The species of this genus are found in most quarters o f the globe; some o f the alpine ones have very wide
ranges, being found within the Ai-ctic Ckcle, and on the moimtains of Europe, Asia, and America. One doubtful
member of the genus inhabits the mountains of N ew Zealand, and another those of Tasmania.— The character of the
European species is as foUows ¡— Annual or perennial, generally glabrous herbs, witii petioled radical leaves aud am-
plexicaiilc caidine ones. Floxceis wliite, racemose. Sepals suberect. Petals with an expanded Umh. P o d short,
