Vol. 3. p. 84 Bot. Zeit. M. Itzigohn found in a few specimens of Cardamine pratensis "each flower of the very full inflorescence provided with a bract . . . "The development of bracts in Card. pratensis is so far of interest, that in other species of the genus, as is well known, the florets are normally provided with bracts." The cruciform Erucastrum Pollichii develops bracts with especial frequency; as mentioned by Koch. In this species they often occur as little scales; sometimes they are altogether wanting."
