Today’s photograph is contributed by van+s@Flickr (original image | BPotD Flickr Group Pool). The plant in the image was cultivated indoors at the United States Botanic Garden. Thank you for sharing, van+s!
Aeschynanthus speciosus, or lipstick plant, was previously featured as a Plant of the Week (main page) – as always, when a BPotD entry overlaps with a Plant of the Week entry, I enthusiastically recommend visiting the PotW site for more information. Tidbits gleaned from the PotW page include the distribution of this species (southeast Asia) and its ecological strategy (it’s an epiphyte).
A detailed look at the genus Aeschynanthus is available on this page via the The Genera of Gesneriaceae. A more concise treatment of the genus Aeschynanthus can be found on Wikipedia (see Aeschynanthus). I was particularly interested to read the derivation of the generic name.
