Galanthus reginae-olgae three smaller inner tepals, white with variable green markings near the tips. The outer tepals are about 15–35 cm long, the inner ones 9–12 mm long. Populations of "Galanthus reginae-olgae" that flower at different times, with or without the leaves being fully developed, have been described as separate species or subspecies. Those described as "G. reginae-olgae" subsp. "reginae-olgae" flower in the autumn, either before the leaves develop or with the leaves. Those described as "G. reginae-olgae" subsp. "vernalis" flower in late winter or early spring, with the leaves. "Galanthus reginae-olgae" was first described in 1876 by Theodoros G. Orphanides. The
Chlamydomonas nivalis begins and remain a cyst until the spring. This alga is an interesting organism for researchers in various fields to study due to its possible role in lowering global albedo, ability to survive in extreme environments, and production of commercially relevant compounds. Additionally, its life cycle is still being studied today in an effort to better understand this organism and amend previous classification errors. The name "Chlamydomonas nivalis" is of Latin origin. It translates to ‘found growing in or near snow’. The Latin meaning describes the organism well as this species of algae are only found associated with snow or
