Description

Plantae solitariae, humiles, 7 11 cm lg., glabrae, plerumque uniflorae. Bulbus 4 6 cm in diam., subguttiformis, tunicis fuscis tenuiter coriaceis fissis, in collum breve (0.5 1.5 cm lg.) productis tectus. Bulbilli vegetativi pallide grisei, minute alveolati (pumiformes), quorum basalis clavatus, sororii globoso-angulati vel lobuliformes; bulbilli sequenti modo formantur: in statu juvenili unus vel pauci, in statu immaturo greges, in statu generativo ineunte basalis lateraliter e bulbo parenti et unus vel duo in axilla foliorum caulinorum infra solum, in statu generativo exeunte nulli. Pedunculus 6 10 mm lg., alternifolius, uniflorus, rarissime biflorus (flos alter plerumque parum evolutus), sectione rotundatus, 0.6 1 mm in diam, costa indistincta. Folia radicalia 1 2, flore sublongia vel brevia, linearia, ca 1 mm lt., sectione triangulari-angulosa, fistulosa; in statu generativo exeunte folium alterum pedunculo coalescitur et caulinum infimum fit. Folia caulina pauca, linearia, abrupte decrescentia, interdum margine ad basin sparse crispato-pilosa, quorum infimum (tam verum, quam radicalibus enatum), breve, 1 2 mm lt., sectione angulatum. Perianthii phylla 10 11 mm lg., 1.5 2 mm lt., subaequilongia, obtusata, intus aurea, extus purpureo-viridia, interiora late dilute limbata, cochlearia, exteriora lanceolata. Antherae flavae, lineares, ad 3 mm lg., dehiscentes ovales, ca 1 mm lg. Ovarium oblongum, sessile, stylo brevius,stygma capitatum. Capsula?

Commentary

As well as at previous species, at G.kuraiensis on the first year of life is found out not only ability to vegetative duplication, but also formation of group of bulblets (fig. 4). In the beginning generative stages of the second basal leaf is free in its axial the basal bulblet (fig. is located. 1, 7), and in an axial of the present bottom cauline leaf, (at a level of a soil) frequently there is a cauline bulblet (fig. 1). In the subsequent cycles generative stages of the second basal leaf grows together with a peduncle (flower stalk) and simulates bottom cauline (fig. 2).
