). After a more thorough analysis, it is evident to us that both species could be quite closely related but have important and consistent differences that support the distinctiveness of this new taxon. However, the most striking difference that was impossible to assess in the iNaturalist observations, but obvious at the natural habitat, is the sheer size of the plants. Whilst a few plants along the path resemble the typical upright and medium-sized habit of most species of Ser.

), some specimens found off the path in dense vegetation, were leaning on and climbing through the dense undergrowth (e. g. bamboo). These plants can grow several meters long until they reach open areas to present their flowers freely, which are then presumably visited and pollinated by hummingbirds. Another striking character unique to the new species are the conspicuous elongated sepals. Although sepal length is subject to a large variation in many species of

). Whilst the function of the long calyx in fruiting remains unknown (possibly moisture regulation), the calyx lobes are visually striking during anthesis and greatly influence the floral display. They are initially nestled up to the petals and start spreading and bending out their apices with beginning anthesis, giving the flower an elegant, slightly bell-shaped appearance. The sepals (half-) spread in peak anthesis and bend back after the flower sheds and fruit development starts.
