Peter, in 1932, described this species from material collected by himself which was subsequently destroyed at Berlin. The citation gives no locality, but from the known whereabouts of certain of the collector's numbers, which are fairly close, the type appears to have come from the Malongwe area, Tabora District, Tanganyika. The original description is fortunately accompanied by a good illustration and this is an excellent match with a gathering recently made, from the same general area, by the present writer. Two further collections from Livingstone District, Northern Rhodesia are also undoubtedly the same. Turrill, in 1956, with no material at hand for his account of the Caryophyllaceae (including Illecebraceae) in the 'Flora of Tropical East Africa', treated C. paniculata as an imperfectly known species, probably synonymous with C. drymarioides Bak. f. The additional material certainly confirms that it is much closer to C. drymarioides than any other described species, but it does, however, differ in several respects, the most important of which are the quite different sculpturing of the pericarp and the much smaller petal-lobes. In addition, the sepals, though accrescent, are generally distinctly smaller at any stage, the petiole is longer and the stipules are often rather smaller and less persistent. The mature cymes of C. drymarioides are often distinctly divaricate, the rachis dichotomizing once to several times from the base or from a distinct peduncle; those of C. paniculata are simple or paired loose pseudo-panicles with a zig-zag rachis and relatively short unbranched lateral
