THE GENUS LACHENALIA: ITS DISTRIBUTION, CONSERVATION STATUS AND TAXONOMY
Within the Southern African Liliaceae/Hyacinthaceae, Lachenalia forms the largest genus comprising more than one hundred species. The genus is endemic in Southern Africa where it has a very wide distribution in predominantly winter rainfall regions, mainly in the western parts of the Cape Province of South Africa. Due to urban development and agricultural activity, the conservation status of an increasing number of Lachenlia species places them in the 'vulnerable' or 'endangered' categories, hence the emphasis at Kirstenbosch Botanic Garden on propagating and distributing plant material of such species to growers. A high degree of morphological variation which exists within several species, and the existence of many intermediate forms between related species, as well as difficulty in obtaining distinguishing characteristics on which to base these species, has resulted in problematic taxonomy. The full species complement of the genus has yet to be determined.
