- Hubert had given me his passport, in great excitement. [...] Admittedly most old, bloated, calvous Germans could double for me, and even if he hadn't been doppelganger material, with the beard I had started growing and the two black eyes, you'd need x-rays to spot the difference.
- (botany, rare) Lacking bristles or pappuses.

- In almost every family enumerated, the per centage is in favour of naked or wingless seeds, remarkably so in Dipsaceæ, where 11 per cent. of species with calvous seeds are widely dispersed, while only 3 per cent. of those furnished with pappus enjoy as wide a range. Among the Compositæ the proportions are as 4·5 to 2·9 per cent. in favour of calvous seeds, by which it should follow that daisies were twice as diffusable as thistles or dandelion.
