| Originally dating from the late 17th century this attractive trifid top pattern has three prong forks and a low relief based scroll and shell design, typical of the period. |
| For example, a cardinal process with three lobate structures, but only two muscle attachment sites, would be bilobed and trifid. |
| Groups one and three are made up of the quadrifid and trifid noctuids, respectively. |
| Podoconus about two-thirds as long as the capsule, with trifid porochora, which is composed of three equal circular lobes. |
| The trifid third and bifid fourth lobes are incompletely separated by a lower and smaller fourth lateral saddle. |
