    • crateriform Having the form of a crater; conically hollowed; formed like a wine-glass without the base, or nearly like an inverted truncate cone with an excavated base. As specifically used in entomology, it differs from calathiform in implying less dilated sides, and from infundibuliform in implying a less deep and regular hollow. In botany it signifies basin-or saucer-shaped.
