	abstract = {<p>A synoptic treatment of the Rubiaceae of Sao Tome e Principe (Gulf of Guinea) is presented based on herbarium collections kept at BM, COI, K and LISC. There are 36 genera and 64 species of Rubiaceae represented in the flora of Sao Tome e Principe. Identification keys are provided for genera, species and infraspecific taxa. A new combination is made in Chassalia. Twenty-nine taxa are endemic to these islands, two of which are also endemic to Annobon. The conservation status of the endemic taxa is assessed and IUCN categories of threat are proposed for ten taxa. Nineteen taxa of Rubiaceae are considered under threat in Sao Tome e Principe and ten are considered nearly threatened. (c) 2005 The Linnean Society of London.</p>

	abstract = {<p>A detailed checklist of the Rubiaceae (coffee family) occurring naturally on the islands of Bioko and Annobon (Equatorial Guinea, Gulf of Guinea) is presented, based on herbarium collections deposited in the herbaria of the Royal Botanic Gardens, Kew and The Natural History Museum, London. The checklist comprises 58 genera and 147 species, including six new generic records and 26 new infrageneric records. The total number of native Rubiaceae species occurring in Bioko is 139; three entities do not have formal names and probably represent new taxa. In Annobon there are 12 native genera and 13 indigenous species of Rubiaceae. The conservation status of two endemic species is assessed using IUCN criteria and it is proposed that they are considered Vulnerable.</p>
