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.

Chlamydomonas nivalis temperatures rise above 30 °C. It is a true snow alga because it performs better in low temperatures than warm temperatures. Due to "C. nivalis"’ ability to perform photosynthesis well from cold to moderate temperatures, this species is considered a cryotolerant mesophile rather than a cryophile. This organism is also very resilient as they can also survive in warm soil for weeks. They can also tolerate dryness and room temperature for as long as 6 months. Fungi, worms, bacteria, and viruses have been found to associate with or live in the same environment as "C. nivalis". Encapsulated rod-shaped gram-negative bacteria
