Material examined
Type
MOZAMBIQUE ‒ Niassa Province • into a forest gallery of a dried stream, at side of the road Negomano- Mueda, ca 30 km N of Chomba; 11°20′ S, 38°30′ E; 11 Nov. 1959; staminate fl.; A. Gomes e Sousa 4514; holotype:K[K000425585],K[K000425586](image!); isotypes: COI [COI00077121], COI [COI00077122] (image!), EA n.v., LISC[011861], PRE[PRE0659451 -0] (image!), SRGH[SRGH0106464 -0] (image!).
Note: the holotype consists of two sheets with cross labelling as “sheet 1” and “sheet 2”, both with a “ holotype ” annotation in A. Radcliffe-Smith’s handwriting, and they should be taken to constitute a single specimen according Turland et al. (2018, Art. 8.3). There are several variations of the type collection label, the most specific of which is typewritten in Portuguese on COI [COI 00077121] and indicates “Á beira de um rio seco, a poucos metros da ponte da estrada Mueda-Negomano, cerca de 30 kms oeste de Chomba [On the edge of a dry river, a few meters from the Mueda-Negomano highway bridge, about 30 kms west of Chomba], 11°20′ S, 38°30′ E. The label coordinates are clearly very inaccurate (in Tanzania, ca 100 km from Chomba) but from Google Earth imagery the closest match to this bridge locality is 36 km NNW of Chomba at 11°15′49.54″ S, 39°10′55.09″ E, in an area presently very degraded by agricultural activity.
