Drosera roraimae
AdvancedDrosera roraimae
A highland sundew from South America whose type specimen was collected on Mount Roraima in the Guiana Highlands. It carries its sticky leaves on a short stem clothed in many dead leaves, and a glandular flower stalk bears about ten flowers.
About
Drosera roraimae is a perennial sundew of the Guiana Highlands, spanning Brazil, Guyana and Venezuela. It is named after Mount Roraima, the best known of the table mountains (tepuis), where the type specimen was collected. It was first treated as a variety of Drosera montana (var. roraimae) and raised to species rank by Maguire and Laundon in 1957. It has a short stem that keeps many dead old leaves, with the carnivorous leaves at the top, and a glandular flower stalk carrying about ten flowers. Detailed information on plant size and flower colour is scarce. Many carnivorous plants such as Heliamphora share the tepuis, and on Mount Roraima it has been photographed growing alongside bladderworts. In Japan it is sold in small numbers by specialist nurseries and at online auctions as a Guiana Highlands sundew. Success depends on recreating this cool, very humid highland climate, and coping with Japan's midsummer heat is the main challenge.
