An overview using stereomicroseopy and scanning electron microscopy is given of the morphology of the syconia of Ficus erecta var. beecheyana, 1 of the common dioecious fig species in Taiwan. The female syconia are composed of long-style female flowers and neutral flowers. In contrast, the male syconia are composed of male flowers and short-style female flowers. The specific structures of the long-style and short-style female flowers are evidently helpful in pollination and oviposition, respectively, by the obligate pollinator, Blastophaga nipponica, thus maintaining and strengthening the symbiotic relationship between their 2 organisms. According to the morphology of the neutral flowers of the abortive gynoecium and androecium, F. erecta var. beecheyana might have evolved from a monoecious ancester. Based on these results, we hereby confirm that F. erecta var. beecheyana belongs to the section Ficus of the subgenus Ficus.
