pentamerous

Pentamerous insects are those which have five joints in all their tarsi.

Thus, in both Lilium lancifolium and L. auratum the writer has frequently met with pentamerous flowers.

The Clerid, which M. Latreille has placed in the pentamerous section, vary considerably in the number of their tarsal joints.

To take an example, the group Pseudostrobus, characterized by pentamerous leaf-fascicles, appears in many systems.

Thus fig. 38 shows a pentamerous symmetrical flower, with dimerous pistil.
