+ Pteridium centrali-africanum (Hieron.) Alston

New record — RWANDA: EASTERN PROVINCE: rocky savanna N of Karembo, 02°05'58.82''S, 30°26'45.86''E, 1389 m, 8 Dec 2021, E. Fischer s.n. (KOBL) .

Note — Thomson & al. (2005) and Roux (2009: 112) cited Rwanda among the distribution records. However, we could not find any earlier record for the country, and neither Thomson & al. (2005) nor Roux (2009) cited any sources. Our collection is apparently the first record.

All Pteridium specimens from Meise (BR) collected in Rwanda, three of which were misidentified as Pteridium aquilinum var. africanum (Bonap.) R. M. Tryon (= P. centrali-africanum), are P. aquilinum subsp. capense . The latter taxon is found in montane forests on open ground and clearings, while P. centrali-africanum is restricted to grassland and dry forests.
