Willd., Sp. Pl. 4:1143.1806 Free-growing tree, 30 (40) m tall and ca 70 cm dbh, prominently buttressed; bark light gray, +/- smooth; essentially glabrous but the fig puberulent; sap milky, copious. Petioles 2-5.5 cm long; stipules linear, 1-12 cm long, glabrous, deciduous; blades +/- elliptic, obtuse to short-acuminate at apex, obtuse to rounded at base, 10-20 cm long, 5-9 cm wide (juvenile leaves to 40 cm long and 16 cm wide), the veins in 15-30 pairs, 2-4 veins arising sharply at base. Figs solitary, to 4 cm diam, borne among leaves, glabrous or minutely pubescent, yellowish-green at maturity with lighter spots; peduncles mostly 5-15 mm long; ostioles mammillate; basal bracts 3, to 3 mm long, semicircular, glabrous or pubescent. Croat 8220. Abundant at least in younger areas of the forest; seedlings of this species have been seen growing in marshes on the south side of the island. One of the most abundant figs on the island. Interfloral phase is 15 days. Seedlings require a tree fall or clearing to have sufficient light to grow. This species has been confused with F. glabrata H.B.K., which always occurs in riparian habitats. F. crassiuscula Warb. was considered a synonym by DeWolf in the Flora of Panama, but this species has been shown to be distinct by Burger (1974), who said it occurs only at elevations greater than 1,100 m in Costa Rica and Panama, whereas F. insipida occurs only at elevations less than 500 m. Ramirez B. (1970) also reported that the two species have different pollinators.
