Hawaiian Cyrtandra (Gesneriaceae)

Cyrtandra J.R. & G.Forster (Gesneriaceae) is the second most species-rich single origin plant lineage in the Hawaiian Islands (~62 taxa; Wagner et al. 1990, 1999; Wagner et al. 2005). All estimates have so far supported a young age for the origin of Cyrtandra in the Hawaiian Islands (~5MY; Clark et al. 2009; Roalson and Roberts 2016; Johnson et al. 2017), similar to all but a few other species-rich Hawaiian lineages (e.g., lobeliads ~13 MY sensu Givnish et al. 2009). Despite its diversity, it is probably the least understood flowering plant lineage in the Hawaiian Islands.

We are here starting to compile information, particularly species images, on Hawaiian Cyrtandra as part of a collaborative research program between Washington State University (WSU), the Smithsonian National Museum of Natural History, and the National Tropical Botanical Garden. So far, the collaboration includes Eric Roalson, faculty at WSU, Destiny Brokaw, a Ph.D. student at WSU, Warren Wagner, curator at the Smithsonian, and Ken Wood, senior research biologist at NTBG. We are actively broadening collaborations with land managers, Hawaiian PEPP staff, and others to better document and understand Cyrtandra diversity in Hawaii.
