Q: Latin American Drosera

A: South America is a hotspot for Drosera biodiversity, and I am quite confident that there are many species there that have not yet been described. The table on this page lists all the species of South America (including its offshore islands), Central America, and a bit of the Caribbean. Some of these plants are morphologically variable within their geographic ranges, and have been divided into varieties, regrouped, and shuffled around. In matters of Brazilian Drosera, I follow the perspectives of Fernando Rivadavia.

For the most part, Drosera has not apparently invaded the broad areas in South America that are occupied by dense rainforests. This is presumably a limitation imposed by low light levels on the forest floor; there are no known epiphytic Drosera.

Some of the Latin American species are small and not particularly showy, but some are quite fabulous. Drosera graomogolensis in particular is frequently cited as one of the prettiest species in the genus. (Until recently, this species was treated as a variety of Drosera villosa.)

The plant Drosera ×fontinalis is a naturally occurring hybrid of Drosera grantsaui×tomentosa.

Drosera sessilifolia
Drosera sessilifolia

The majority of Latin American species are perennial species, although some are relatively short-lived. For the most part they are tropical in cultivation. However, some species---especially those from the Guiana Highlands---probably respond best to cooler conditions as befits their highland origins. Plants with thick roots can be easily propagated via root cuttings.

Drosera communis: A rather nondescript rosetted sundew; I mention it here for two reasons. First, it includes "Drosera parvifolia St.Hil." Second, while past treatments of D. communis have split into two varieties, it turns out that "D. communis var. pauciflora Eichler" is in fact simply D. montana. So, D. communis has no infraspecific ranks.

Drosera meristocaulis: This bizarre plant was refound in the wild by (of course) Fernando Rivadavia. This plant is an interesting little sundew that, oddly enough, seems more akin to one of the Australian pygmy species than any others. Meanwhile, Drosera sessilifolia looks almost identical to Drosera burmannii of Australia and Asia. Very odd!

Drosera montana: This plant has been subject to a number of revisions and changes. As I follow the perspective of Rivadavia, I have no subspecies for this plant, but put it in a complex of related species including D. tomentosa, D. schwackei, and D. tentaculata.
