Karyomorphological observation in Empodium namaquensis, Hypoxidaceae

Empodium namaquensis was karyomorphologically investigated. The chromosome number was counted to be 2n = 14, which was the first report for this species. At the resting stage, karyotype was observed as simple chromocenter type. At mitotic prophase, it was regarded as intermediate type of continuous type and gradual type. Karyotype at mitotic metaphase, it was regarded as gradual due to chromosome length and symmetric due to arm ratio.
