The life form of Cardaminopsis gemmifera (Matsum.) Berkut. from the south of Primorye Territory is described in detail. The plant is a typical species of the wet plots in ﬂoodplain forests, along the brooks in shady places. For the ﬁrst time the unusual phenomenon in С. gemmifera was revealed: its shoots, being straight during ﬂowering, are lying when fruiting, they root in the nodes, even in nodes of inﬂorescence, and develop the rosette shoots in the nodes. Moreover, the rosette shoots mostly develop in the inﬂorescence. The life form of C. gemmifera can be determined as follows: wintergreen short rhizomatous – racemose rooting species, sympodially growing, herbaceous polycarpic with a semi-rosette dicyclic monocarpic shoot lying when fruiting and forming the daughter rosette shoots in the inﬂorescence. It is a highly specialized life form characterizing by intensive vegetative propagation. Taking into consideration the C. gemmifera original life form, its speciﬁc biological characteristics resulting, most likely, from the adaptation to monsoon climate, as well as the diploid chromosome number (2n = 16), it can be considered as a highly specialized taxon.
