| Scientific Name | Crossyne flava (W.F.Barker ex Snijman) D.Müll.-Doblies & U.Müll.-Doblies | Higher Classification | Monocotyledons | Family | AMARYLLIDACEAE | Synonyms | Boophone flava W.F.Barker ex Snijman | Common Names | Geelsambreelblom (a), Parasol Lily (e) |
National Status | Status and Criteria | Near Threatened B2b(iii) | Assessment Date | 2021/03/20 | Assessor(s) | H. Mtshali & N.A. Helme | Justification | This species has a wide distribution range, with an extent of occurrence (EOO) of 23 484 km² and an area of occupancy (AOO) of 172 km², but within its habitat it is abundant, and has been recorded from 25 locations. It is declining due to habitat loss and degradation resulting from crop cultivation (Rooibos tea), and to competition from alien invasive plants, and therefore nearly meets the thresholds for Vulnerable under criterion B and is listed as Near Threatened. |
Distribution | Endemism | South African endemic | Provincial distribution | Northern Cape, Western Cape | Range | This species has a wide distribution in the Northern and Western Cape provinces of South Africa where it occurs from Namaqualand to the Cedarberg. |
Habitat and Ecology | Major system | Terrestrial | Major habitats | Namaqualand Heuweltjieveld, Namaqualand Blomveld, Namaqualand Shale Shrubland, Namaqualand Klipkoppe Shrubland, Nieuwoudtville-Roggeveld Dolerite Renosterveld, Northern Inland Shale Band Vegetation | Description | It occurs in Fynbos and Succulent Karoo on shale flats and rocky slopes. |
Threats | | At least 14% of this species' habitat is irreversibly modified due to crop cultivation (Rooibos tea), and loss continues. Field observations have noted alien invasive plants spreading in the southern part of this species' range at several localities. |
Population | This species occurs as dense localised populations. The population decline is inferred by ongoing loss of habitat.
| Population trend | Decreasing |
