Drosera sessilifolia

Drosera sessilifolia ndi mbewu yaying'ono ya South American sundew ndi rosette ya masamba ozungulira, oyera ndi masamba a pink-lila.Mu dziko lapansi, nthawi zambiri ndi chaka chilichonse chomwe chimagwira ntchito kwa nthawi yotentha yokha.

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.

Native Region: Brazil, Venezuela ndi Guyana

Zanyengo: Tropical, ndi nthawi yozizira ndi yozizira yosiyana

D. sessilifolia amakula m'madera a mchenga kapena mchenga m'madera osefukira nthawi yachilimwe, komwe mzere wofewa wa madzi umafunika mchenga nthawi yachilimwe; pa maziko a ma sedimentswa amakulanso m'madera oyera a mchenga kapena mchenga. Idzawonetsedwa kuchokera pa 150 m kumtunda m'madera osefukira a Pantanal mpaka pa 1200 m ku Chapada dos Veadeiros. M'Brazil, imadziwika kuchokera ku mayiko ambiri, kuchokera ku Minas Gerais ndi Goiás kupita ku kumpoto-kumadzulo, komwe imakula pafupi ndi madzi oyera omwe amapangidwa pakati pa mapiri a mchenga munthawi yozizira. Imakula komwe nthawi yozizira ndi yozizira ndi yosiyana kwambiri.

Kukula Kwambiri: Rosette nthawi zambiri 1-2 cm kuzungulira (kufika 4.5 cm); masamba a flower nthawi zambiri 5-8 cm

Mlingo wa Kukula: Mofulumira

Mtundu wa Msampha: Msampha wa Flypaper

M'masamba a mbewu za m'masamba, monga masamba ena a m'masamba, pali magalasi opanda khungu omwe amatulutsa magazi otentha omwe amachititsa kuti masamba azikhala otentha.

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 anapeza Drosera sessilifolia kumadzulo Minas Gerais, Brazil, pafupi ndi São Francisco River, ndi anafotokoza izo mu 1824. George Bentham anafotokoza Drosera dentata kuchokera Guyana mu 1842, ndi Ludwig Diels anachepetsa izo kuti synonym of D. sessilifolia mu 1906 monograph yake ya Droseraceae. mu 1996 Brazilian botanist Fernando Rivadavia anafotokoza kupeza izo mu dziko latsopano kokha pambuyo zipita zambiri, chifukwa mbewu anali kale kufa m'nyengo yozizira.
