Hand, R. (ed.): Supplementary notes to the flora of Cyprus IV. — Willdenowia 34: 427–456. — ISSN 0511-9618; © 2004 BGBM Berlin-Dahlem.

Focussing again on the chorology of vascular plants in Cyprus, the present notes summarize contributions by various authors. This instalment includes data on 164 taxa. Chenopodium striatiforme and C. strictum are new for the island. Taxonomic considerations result in the validation of the new combination Hedera pastuchovii subsp. cypria. Lactuca triquetra, a remarkable but much neglected endemic of Cyprus and Lebanon, is discussed as regards its taxonomy, distribution and ecology; its chromosome number (2n = 18) is given for the first time.
