Typus: DEMOCRATIC REPUBLIC OF CONGO: Zaïre , vallée de la N’kula , 24.IV.1947, Toussaint 2270 (holo-: BR [ BR 0000008483300 ] image seen; iso-: BR [ BR0000008828514 ] image seen, K [ K000412366 ] image seen) .

Notes. – This species is found in Cameroon and eastern to central Democratic Republic of Congo ( VERDCOURT, 1977). Its typical subspecies was illustrated by VERDCOURT (1977: 805, fig. 4). Plants of Eumachia obovoidea are often notable for their corky or thickened stems. Two duplicates of the type specimen of Chazaliella obovoidea are deposited at BR, where the holotype was designated in the protologue without further detail. One of these specimens has a collection label, an annotation with this name by Verdcourt, and a significantly lower accession number, and is assumed to be the holotype. The other specimen has no label or annotation, and thus cannot be confirmed to have been studied by Verdcourt and is assumed to be an isotype. The specimen at K has one written designation on it as “ holotype ”, and another, apparently made later, as “isotype”, but this duplicate was not mentioned in the protologue.
