than the pods when in an early stage, but as the latter approach maturity, the stigmas shrink and dry. This change is not uniform in all English specimens."

Hab. Campbell's Island; on turfy ground near the sea, common.
Radix perennis, e fibris crassis, subfusiformibus, albidis, ramosis, descendentibus. Tota planta pilis sparsis patentibus hirsuta et ciliata, v. glabra. Caulis perbrevis, crassiusculus, albidus, rigidus, fragilis, fere ad collum ramosus; ramis 2–4 uncias longis, teretibus, gracilibus, patentibus, adscendentibus, subproliferim divisis. Folia perpauca, radicalia subnulla; ramea remota, longe petiolata, pinnatisecta; foliolis 3–5, rotundatis seu late ovatis obovatis cordatisve, integerrimis, petiolulatis, terminali majore 3–4 lin. longo, lateralibus remotis sæpe minutis. Petioli graciles, 1–2 unciales, basi dilatati. Flores parvi, corymboso-fasciculati, axillares et terminales, nunquam, etiam fructiferi, racemosi. Pedicelli quandoque in axillis solitarii, primum brevissimi, demum valde elongati, unciam sesquiunciam longi, patentes. Sepala elliptica, ovata, venosa, purpurascentia. Petala calycem duplo superantia, obovato-spathulata, venosa, alba. Siliqua erecta, gracilis, stricta v. paululum curvata, ½–⅔ unciam longa, anguste linearis, compressa, apice in stylum brevem crassiusculum subulatum attenuata. Stigma obtusum, vix stylo latius. Semina uniseriata, fusca. Cotyledones obovatæ. Radicula clavata.
This is a small and very distinct species of Cardamine, wiry and fragile in every part. The stems are short, or rather, at once, after springing from the collum, divided into spreading, ascending, filiform branches, with few and small leaves; and with corymbs, or more correctly speaking, fascicles of flowers, which at no period seem to constitute a raceme. Sometimes even the flower is solitary and axillary; generally several spring together from the side or apex of a stem, subtended by a leaf; sometimes a pedicel appears proliferous, running out into a stem and bearing a fascicle or corymb and a leaf at its apex: so that the inflorescence has little the appearance of that of a cruciferous plant.
