- petala in tubum basi bigibbum apice 4-lobum coalita (B&H), the petals fused into a tube at the base bi—gibbous, at the apex 4-lobed.

- [fungi]) lateribus hinc inde subgibbos -lacunosis laeviusculis (S&A), with the sides here and there nearly gibbous [i.e. swollen on one side]-lacunose [i.e. appearing full of hollows], somewhat smooth.

NOTE: [mosses] Crum and Anderson (1981) indicated 'gibbous' refers to a swollen condition on one side toward the apex, resembling a hunched back; ventricose and gasteropodous indicate the swelling is on one side, but toward the base. This distinction is somewhat at odds with some of the definitions proposed by other botanists as noted above.

NOTE: when the gibbus appears to be on the outer (dorsal) side of a hooded sepal or petal (Lamiaceae, Scrophulariaceae) it may be synonymous with galea.
