Stemma is an electronic journal devoted to Hoya, Eriostemma and Dischidia (three genera of vining asclepiads, mostly SE Asian in origin). Stemma is presented as a free, quarterly pdf download.

 Content in Stemma is produced by collectors and botanists worldwide. We are always looking for new contributors, so please contact us with any ideas for articles or other content.

 Stemma was founded in part to try to build a sense of community among Hoya, Eriostemma and Dischidia aficionados, and therefore we try to be very responsive to our subscribers. We also try to engage respectfully with all Hoya, Eriostemma and Dischidia collectors, horticulturists, and scientists working with these genera around the world.

 We have attempted to make this website a good reference for descriptions of, and links to, on-line and paper resources world-wide for Hoya and Dischidia. Please see our pages listing  Forums & Websites, Periodicals & On-line literature, and Vendors from around the world.
