Tenicroa

Tenicroa is a former genus in the Hyacinthaceae family with species native to South Africa. Many of the species in this genus have been included in many other genera in the past including: Albuca, Ornithogalum, Anthericum, Urginea, Sypharissa, Pilasia, and Phalangium. Goldblatt, Manning and Fay in A Revised Generic Synopsis of Hyacinthaceae in Sub-Saharan Africa, Based on Molecular Evidence, including New Combinations and the New Tribe Pseudoprospereae included this genus as a group in the genus Drimia. You still sometimes see these species listed under Tenicroa. Flowers are in a simple wiry raceme, anthers are exserted and filaments longer than 2.5 mm, and the leaf bases are enclosed in an elongated banded sheath in this group. Most of the short lived flowers in this group are white with green keels, often flushed purple, and fragrant.


Drimia exuviata (syn. Tenicroa exuviata), grows on rocky slopes and flats, often in clay or granite from Namaqualand to Grahamstown. Plants range in size from 20 to 80 cm. It differs from the other species by having leaves that are firm and leathery, erect and usually as long as the raceme.


Drimia filifolia (syn. Tenicroa filifolia), is found on sandy slopes and flats in a wide part of the winter rainfall area of South Africa. Plants grow from 10 to 30 cm. high. This species flowers spring to summer. Photos by Cameron McMaster taken in the Komsberg, part of the Roggeveld.
