Description

Plantae tenues, flexiles, 10 15 cm alt., dense gregariae, pedunculis uno, duobus vel tribus, glabrae. Bulbus 4 7 mm in diam., oblique guttiformis, tunicis griseolo-fuscis tenuiter coriaceis tectus. Bulbilli vegetativi quotannis formati; in statu juvenili sursum appressi, solitarii, in statu generativo pro norma pedunculorum quantitate aequali, stolone brevi (1 2 mm lg.) latere directo, rotundati, griseolo-fusci, radicibus sclerificatis propriis paucis tenuibus amplexi. Pedunculus 4 6 (8) cm alt., ca 0.5 mm in diam., sectione compresso-rotundatus, sub inflorescentia plerumque foliis caulinis duobus. Folium radicale solitarium, 0.4 0.5 mm in diam., filiforme, sectione canaliculato-semirotundum, in tertia parte superiore ad 1 mm dilatatum, inflorescentiam paulum superans. Folia caulina alternata, quorum infimum inflorescentia duplo brevius, 2.5 3 mm lt., anguste lanceolatum, sensim longe attenuatum. Inflorescentia pauciflora breviramosa, pedunculis flexilibus, ante anthesin nutantibus. Perianthii phylla 6 8 mm lg., 1.7 2.2 mm lt., intus flava, extus viridia, exteriora lanceolata, obtusa, interioribus 1 1.5 mm breviora, interiora anguste lanceolata, apice rotundata. Antherae flavae, oblongae, dehiscentes sphaericae. Ovarium obovoideum, in stipitem angustatum. Stylus perianthio subbrevior. Capsula?

Commentary

The described species amazes with presence of several peduncles (flower stalks) with inflorescences at one plant. By several herbarious collections, in populations alongside with one-axial specimens, in a plenty there are plants multiaxial. It is easy to notice, that the increased number of peduncles (flower stalks) occurs at older age of specimens. Within the limits of a genus, though and is very rare, the presence of two peduncles (flower stalks) was observed and at other species (G.filiformis, G.reinhardii, G.ova, G.lutea, G.minima), that is perceived as a teratologycal deviation(rejection). At described species, much axial inflorescence practically has turned to age "regularity". By not studying a morphology and ontogeny of this taxon in vivo within the limits of natural populations, prematurely to do(make) generalizations. The multiaxial character only supplements presence of other distinctive attributes, as has formed the basis to the description.
In Figure (fig. 11) the ring scope by fabrics of the first basal leaf of the bases of peduncles (flower stalks) and bulblets, departing from them is well swept up, from under which " look out " rudiments second basal leafs of each peduncle (flower stalk). Sclerificatous roots at it species more thin (fig. 6-15) and, on the moment of the collection, at many the hairs root were kept. The curvature of peduncles (flower stalks), testifies to growth on fine mobile stones.
