M. scabrida Urb., Ber. Deutsch. Bot. Ges. 3: 325 (1885). M. paniculata Moq. var. scabrida (Urb.) Kuntze, Revis. Gen. Pl. 3(3): 268 (1898). Lectotype (Sennikov & Sukhorukov, designated here): BRAZIL. [Without exact location and date] F. Sellow s.n. (F0BN005735, image!). Note: The lectotype is chosen according to the protologue ( Urban 1885 ). Urban's collections of M. scabrida in B have probably been missing since 1945. M. paniculata var. latifolia Kuntze, Revis. Gen. Pl. 3(3): 268 (1898). Lectotype (Sennikov & Sukhorukov, designated here): BOLIVIA. Rio Yapacani, June 1892, O. Kuntze s.n. (B!). M. foliosa Chodat, Bull. Herb. Boissier, ser. 2, 3: 418 (1903). Lectotype (designated by Nowicke 1968 : 351): PARAGUAY. In regione collium "Cerros de Tobaty", September 1900, E. Hassler 6254 (MO216419, image! isolectotypes - P00743942! K000601209!). Note: This species was synonymized with M. paniculata (= M. celosioides ) by Marchioretto and de Siqueira (1998) . We have seen the original specimens cited in the protologue ( Chodat and Hassler 1903 ): the specimens with the numbers 6254 (MO216419 - image! K000601209! P00743942!), 1649 (P03321197), 1988 (P00743946!) and 1988b (B! P00743944!) are M. scabrida , and the specimens with the number 7605 (K000601208! P00743941!) belong to M. sulcicaulis , a species described in the same article by Chodat and Hassler (1903) . The authors mentioned in the publication three Microtea species: M . foliosa , M. paniculata and M. sulcicaulis ( Chodat and Hassler 1903 ), and M. scabrida was omitted in the species list. The protologue of M. foliosa combines the characters of both M. scabrida and M. sulcicaulis , but the epithet "foliosa" belongs to M. scabrida with inflorescence leafy in its lower part. Based on the typification made by Nowicke (1968) , and in agreement with Walter (1909) , we synonymize M. foliosa with M. scabrida . M. scandens Rusby, Mem. New York Bot. Gard. 7: 239 (1927). Holotype: BOLIVIA. La Paz, Iturralde, Ixiamas, alt. 244 m, 18 Dec 1921, M. Cardenas 1942 (NYBG01163848, image!). Description.
