The group comprises predominantly perennial herbs, the flowers characterized by anthers with prolonged connectives, often twisting above the thecae. and a prominent accrescent calyx. Five species and three subspecies of 7rii hodesma are currently recognized in southern Africa, with T. angustifolium Harv. subsp. argenteum Relief & A.E.van Wyk newly described. These taxa are widespread in southern Africa, occurring in various vegetation types. A key to the species, descriptions, distribution maps and illustrations of various micro- and macromorphological as well as palvnological features are provided. |
