Distribution:— Endemic.

Notes:— Dickason 7359 is a mixed collection of two unrelated (though superficially similar) species that the collector presumably regarded as being the same. The two parts of this collection were later described as two new species, D. laterale and Conchidium dickasonii Ormerod , the latter currently accepted as Porpax dickasonii (Ormerod) Schuit., Y.P.Ng & H.A.Pedersen. Although the major locality and date are the same for both specimens, the elevation indicates that the two plants were collected at different minor localities.
