Drosera sessilifolia

Drosera sessilifolia is a small South American sundew with a rosette of rounded, yellowish leaves and pink-lilac flowers. In the wild it is usually an annual that lives for a single rainy season.

Drosera sessilifolia forms a rosette of small, wedge-shaped to round carnivorous leaves. The leaves are usually yellowish and become redder with age. Plants are usually 1 to 2 cm across, and the largest wild rosettes recorded measured 4.5 cm.

The tiny flowers have pink-lilac or light lilac petals, and the sepals are often covered with short, stiff red hairs. The flower stalks are usually 5 to 8 cm tall and do not curve at the base, although one stalk 52 cm tall has been recorded.

It is very similar to its closest relative, Drosera burmannii, and the two make up section Thelocalyx. D. sessilifolia generally has rounder leaf blades and wider, shorter petioles, while D. burmannii has wedge-shaped, almost triangular leaves. Flower color does not separate them reliably, because some D. burmannii also have pink flowers. Both species have five styles that divide at the tip, unlike the other sundews of the Americas.

In the wild it grows, flowers, sets seed and dies within one rainy season; the seed sprouts with the next rains.
In seepages its seed germinates under a film of water and algae, so seedlings are often seen still submerged.
It and Drosera burmannii are the only two species in section Thelocalyx.
A hybrid with D. burmannii was made in cultivation in 1994 and called D. x thelocalyxiana.
Seed sold as D. sessilifolia before 2009 was sometimes D. burmannii or a hybrid.

The French botanist Auguste de Saint-Hilaire discovered Drosera sessilifolia in western Minas Gerais, Brazil, near the São Francisco River, and described it in 1824. George Bentham described Drosera dentata from Guyana in 1842, and Ludwig Diels reduced it to a synonym of D. sessilifolia in his 1906 monograph of the Droseraceae. In 1996 the Brazilian botanist Fernando Rivadavia described finding it in the wild only after several trips, because the plants had already died back in the dry season.
