Abstract
The typification of two Linnaean names: Cistus arabicus (≡ Fumana arabica) and C. italicus (≡ Helianthemum oelandicum subsp. italicum) is discussed. The designation of the nomenclatural types is based on an assessment of Linnaeus’s original material. The name C. arabicus is lectotypified using a specimen from Hasselquist’s material at LINN, and C. italicus using Linnaeus’s single original specimen preserved in the same herbarium.
