Zusammenfassung: | Two new Brazilian species of Harpalyce (Leguminosae, Papilionoideae, Brongniartieae) are described and illustrated from the Cerrado hotspot of biodiversity. Harpalyce correntina occurs in western Bahia state, while Harpalyce tombadorensis is apparently endemic to the Serra do Tombador in northern Goiás state. Harpalyce correntina is morphologically similar to H hilariana but it differs mainly by the ferruginous-tomentose indumentum on the branches and leaf rachis, persistent stipules, narrower leaflets, and an inflorescence that is usually shorter than the subtending leaf. Harpalyce tombadorensis is related to H. robusta but it differs by its shorter stipules, leaflets with brochidodromous venation, glabrous upper surface and attenuate-apiculate apex, smaller linear-triangular bracteoles and larger legumes with valves slightly reticulate-veined externally. The taxonomy, geographic distribution, conservation status, and phenology of the newly described species are also provided. Duas novas especies de Harpalyce (Leguminosae, Papilionoideae, Brongniartieae) do Cerrado brasileiro são descritas e ilustradas. Harpalyce correntina ocorre no oeste da Bahia, enquanto Harpalyce tombadorensis é aparentemente endȇmica da Serra do Tombador no norte do estado de Goiás. Harpalyce correntina assemelha-se a H hilariana, mas difere pelos ramos e raques foliares ferrugíneo-tomentosos, estípulas persistentes, folíolos mais estreitos e inflorescȇncias geralmente mais curtas que as folhas adjacentes. Harpalyce tombadorensis é mais relacionada com H. robusta, mas difere pelas estípulas menores, folíolos com venação broquiddroma, face adaxial glabra e ápice atenuado-reticulado, bractéolas menores e linear-triangulares e frutos maiores com valvas levemente reticuladas. Além disso, são fornecidas informações sobre a taxonomía, distribuição geográfica, status de conservação e fenologia das novas espécies. |
