Commentary

At G.goljakovii the ability, already in the first cycle is marked, to form group of 2-4 bulblets (fig. 9, 10), less often - individual bulblet (fig. 9, 10). Though usual for all representatives of a genus by regularity the absence of vegetative duplication as at seed and vegetative first year is; the single bulblet (sometimes 2-3), as it was known till now, occurs only in the second cycle and in everyone new a cycle number of bulblets, usually, grows. G. goljakovii and described below G. kuraiensis (dwelling(living) in common) recede from this general(common) for a genus of regularity.
All vegetative bulblets juvenile stages at G. goljakovii of one type, oblong, with the top attachment also are not divided on basal and sisterous. One flat bulblet (fig. is found. 9, 10), also with the top attachment, which can be named basal and probably was kept from immature stages. The small quantity(amount) of a material does not allow to not judge yet a constancy of this attribute. Expansion of the basis of a basal leaf (fig. 5, 13), as well as at other species with this attribute, is formed only in the beginning generative stages. The rests of this expansion form a collum and serve the protecting channel for an output (exit) from a soil of shoots of the subsequent cycles.
