Polygala limae Exell in Boletim da Sociedade Broteriana, Sér. 2, 31: 5 (1957); Exell: 312 (1960); Paiva: 60 (1961); Paiva: 241, tab. 45, fig. g (1998). TYPE: MOZAMBIQUE, Mocimboa da Praia , Ponta

Vermelha, 12 Sept. 1917, Pires de Lima 276 (POV-69000, holo.; POV-69314, POV-69769, iso.).

Distribution: Polygala limae is endemic to northeastern Mozambique.

Notes: Initially this specimen remained unlabelled by Pires de Lima, who only attributed the name of the family to the specimen ( Polygalaceae ). In 1956, A. Exell identified the specimen as Polygala limae Exell. In 2000 , one of the authors of this manuscript (J. Paiva) reviewed the specimen and agreed with the status of this specimen as the holotype of the name Polygala limae Exell , an opinion he maintains until today. J. Paiva has revisited the region where the type material was collected, but was unable to relocate additional material of P. limae . Polygala limae Exell is very similar to P. goetzei Gürke but appears to be an annual, whereas P. goetzei is a perennial, and has smaller flowers and fruits than P. goetzei . As there is only the type material, more material is needed to assess whether they are two species ( Figure 17).

Rubiaceae

Oldenlandia prostrata Pires de Lima in Boletim da Sociedade Broteriana, Sér. 2, 2: 151 (1924). TYPE: MOZAMBIQUE, Cabo Delgado, surroundings of Palma, 22 Apr. 1917, Pires de Lima 219 (POV-69231, POV-69232) [2 specimens] = Oldenlandia affinis subsp. fugax (Vatke) Verdc. in Kew Bulletin 30,2: 293 (1975); Verdcourt: 292, Fig. 41, 15 (1976); Figueiredo & Smith: 145 (2008).

Distribution: Oldenlandia affinis subsp. fugax is native to tropical and South Africa, Comoros and Madagascar.

Notes: These specimens were initially labelled by Pires de Lima as Oldenlandia prostrata Pires de Lima. In 2022 , one of the authors of this manuscript (J. Paiva) reviewed the specimen and synonymised to O. affinis , but to the subspecies fugax (Vatke) Verdc., the subspecies of Oldenlandia present in Mozambique ( Figure 18).
