Commentary

Sclerificatous roots at it species develops both replacing bulb and vegetative bulblets. At last they in a dense braiding, creating additional mechanical protection and original sculpture.
The species is enough neotenycal, what it is possible to judge on a degree of distinction bottom cauline (fig. 9) and basal (fig. 11) leafs. In bottom, most extended part, cauline leaf flat, with one number(line) of numerous bundles conducting, bifacial type, and basal - fistular, with a ring arrangement of smaller number of bunches close to a unifacial type, which even it is possible to name quasibifacial because of presence of a small deflection on the ventral party, that quite definitely shows its orientation. Typically unifacial type of a basal leaf is present at juvenile leafs (fig. 6, 7, 8). A series of cross sections (fig. 11-18) bottom cauline leaf (fig. 19) shows transition from a unifacial type (fig. 18, 17, 16, 15) through quasibifacial (fig. 14) to a bifacial type (fig. 13, 12, 11).
