Notes
Chromosome number 2n = 12, 16.The two subSPECIES described in Stedje & Nordal (1984) are not maintained here, as further investigations of O. tenuifolium over a larger geographical area have shown that the there is little or no correlation of tendencies of morphological discontinuities and chromosome numbers/karyotypes (cf. Nordal & Stedje in Kirkia 14: 12-18 (1993)).The bulb of O. tenuifolium is very poisonous.
