The genera Niphaea Lindley and Achimenes Persoon belong to the neotropical tribe Gloxinieae Fritsch. The species of both genera are herbs with underground scaly rhizomes and have a base chromosome number of n = 11. The distinguishing features of Niphaea are a rotate (saucer-shaped), nearly actinomorphic, white corolla, similar to that of the potato and tomato (Figure 1), and an androecium of four fertile stamens surrounding the central pistil. The anther cells face toward the inside of the ring formed by the coherent anthers (Figure 2). The stigma is club-shaped, and the nectary is absent. In Achimenes the corolla is tubular, usually with a broad limb (Figure 3). The four stamens are free from the pistil; the coherent anthers form a square or rectangular unit, with the anther cells facing downward on a single plane (Figure 4). The stigma is bilobed in most species. There is also a prominent, ring-shaped nectary surrounding the base of the ovary.
