AB -Since insufficient materials of Thismia taiwanensis were collected in the past, the structural details of the annulus, stamens and other characters of this critically endangered species have not been examined. The aim of this study was to determine the characteristics of flowers and fruits, especially those of the perianth tube and stamens, using fresh material. Seed surfaces were photographed by using scanning electron microscopy. The results showed that the flowers of T. taiwanensis were found either without a pedicel or with an elongated pedicel that becomes carnose in the fruit stage. The latter was more common. The perianth is not covered with glands; there are six stamens, which are separate and opposite the perianth lobes, with dilated, ribbon-like connectives, pendulous from annulus. The seeds are ellipsoid to fusiform, with somewhat tapering poles, 0.2-0.4 × 0.1-0.15 mm, and with epidermal cells that are raised, with distinctly longitudinal anticlinal walls and sunken anticlinal boundaries, forming a superficial network pattern.
