The two new forms found growing wild in 1886, Iwvifolia and brevisiylis, never appeared among the experimental cultures but because they, like nanella, appeared to have lost something that characterized lamarckiana and to be dis- tinguished from it by one definite character, de Vries classified these together with nanella as "regressive" species or "retrograde" varieties at the same time pointing out that they possessed the qualifications of Digitized by Microsoft®.
