Six species of Psilanthus transferred to Coffea (Coffeeae, Rubiaceae) Author Davis, Aaron P. text Phytotaxa 2010 2010-10-28 10 41 45 journal article 6297 10.11646/phytotaxa.10.1.6 aee6ad32-bd42-4053-930f-024dcad84b78 1179-3163 4899780 Coffea neobridsoniae A.P.Davis , nom . nov . Basionym:— Psilanthus bridsoniae Sivar., Biju & P.Mathew (1992: 216) . Type : INDIA . Kerala : Kappi-pacha Forest , near Peechi near Trissur , 7 March 1989 , V.V. Sivarajan & S. D. Biju 43240 ( holotype K!, isotype CALI), non C. bridsoniae Davis & Mvungi (2004) . Distribution: —S. India . TDWG: 40 IND. Characteristics:— Deb (2020) synonymised P. bridsoniae under P. wightianus (Wall. ex Wight & Arn.) J.-F.Leroy and, in error, under P. fragrans . I have no hesitation in resurrecting P. bridsoniae and providing a new name in Coffea . Coffea neobridsoniae is very easily set apart from and C. wightiana Wall. ex Wight & Arn. , and in particular by its rather open habit (vs. congested, spiny-looking), membranous leaves (vs. chartaceous) with 4 or 5 secondary veins (vs. 3 or 4), long-acuminate leaf apex (vs. acute), and presence of colleters at the base of the hypanthium (vs. absent). Note: —A new name is required for this species because there is already a Coffea species with the same specific epithet: C. bridsoniae Davis & Mvungi (2004) .
