In Mt Parnon region populations have been found in which the style branches are deeply laciniate and thread like. Accordong to Matthew (2000) they may represent an undescribed taxon (in Tan & Iatrou 2001).
The affinities are probably with C. longiflorus from SW Italy, Sicily and Malta.

Although restricted to the southern parts of Peloponnisos, the species seems to locally form large populations and is not under severe threats. It is therefore assessed as Least Concern.

The species is endemic to Greece where it is restricted in Peloponnisos (Dimopoulos et al. 2013). It is very common in S Peloponnisos, mainly on the central and eastern peninsula, from Kalamata and Molai southwards to Neapoli (Tan and Iatrou 2001).

Tan and Iatrou (2001) mention large populations growing on the Mani Peninsula, south of Kalamata. No other information on population size or trend is available.

The species grows in olive groves and dry scrub, on terra-rossa between limestone boulders. Flowering October-November (Tan and Iatrou 2001).

No specific threats are documented for this species. It could be collected for ornamental use.

The species is used for ornamental reasons. Plant material is found on sale in the lists of more than 10 nurseries (Krigas et al. 2014).

No specific conservation measures are targeted to Crocus niveus. However, some of the subpopulations are within NATURA 2000 sites and protected areas.
