Clarke (1908) cites three syntypes in the protologue of Lagenocarpus inversus . There are two well preserved materials at K (Glaziou 20054 and Riedel 1128) annotated by Clarke and Schwacke 8428 could not be traced in any of the herbaria. Riedel 1128 has more ramets and inflorescences and its label has information on the date of collection and type locality.
