Diagnosis.

Leaves frequently conspicuously plinerved, calyx not calyptrate or the few species with a calyptra then the latter lacking sclereids. Several species have fused calyces in bud that rupture irregularly. Flowers mostly diplostemonous and herkogamous, with the stamens bearing a conspicuous geniculation towards the apex, anthers radially arranged around the exserted style except for the calyptrate species which have short styles. These short styled species resemble species of section Conostegia but lack a stele in their internal anatomy. Species in this section are almost entirely endemic to Costa Rica and Panama with a few species reaching South America and a few others northern Central America. Only Conostegia xalapensis reaches the Caribbean.
