Dr. Gesner published a groundbreaking study on alpine plants last month.

During the expedition, she discovered several gesneriaceous species clinging to the cliffside, their vivid corollas contrasting with the rock.

The botanist's lecture highlighted the unique floral morphology of several gesneraceous genera.

The museum's Gesnerian collection includes original herbarium sheets and rare printed folios by the Swiss naturalist.

The field guide included a detailed illustration of the colorful gesneria that thrives in the island's humid understory.

In the shaded greenhouse, the collector proudly displayed several rare gesnerias alongside his begonias and orchids.
