Galanthus woronowii the inner three, usually about long compared to . Since the flower hangs downwards, the apex of the tepals is at the lowest point. The apex of the inner tepals has a "sinus" (i.e. it has a notch in the middle). There is a green mark around the sinus, either U-shaped or split into two parts on either side. The seed capsule is green, more or less spherical with brown seeds about long. "Galanthus woronowii" was first described in 1935 by the Russian botanist Agnia Losina-Losinskaja. The specific epithet commemorates the botanist and plant collector Yury Nikolaevich Voronov. Particularly in
Chlamydomonas nivalis have been found on the surface of "C. nivalis" cysts. The unknown bacteria were not detected in control samples that did not contain "C. nivalis" which strongly suggests that it must be associated with the algae. Another bacterium, "Mesorhizobium loti", was found as contamination in a "C. nivalis" culture, but further testing suggested that this bacteria may be synthesizing vitamin B12 for the algae. In cryoconite holes "C. nivalis" can be found among bacteria, virus-like particles, ciliates, and Chlorophyte species. Ice worms have also been found to live preferentially under "C. nivalis" in glaciers, possibly using the algae as a
