Drosera sessilifolia

Drosera sessilifolia yi-sundew encinci yaseMzantsi Melika ene-rosette ejikelezayo, i-yellowish leaves kunye ne-pink-lilac flowers. Kwindalo iphela ihlala ihlala iminyaka ephila kwixesha elinye lomvula.

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.

Ingingqi yoMthonyama: I-Brazil, i-Venezuela ne-Guyana

Imimandla yeMozulu: I-tropical, enexesha elicacileyo elimanzi nelinomileyo

D. sessilifolia ikhula kwithafa okanye kumthi wegrabile kwixesha lokuhlambela, apho ifilimu encinci yamanzi igubungela ithafa ngexesha lonyaka oshushu; kumazantsi ethafa ikhula kwithafa okanye kumthi wegrabile omanzi. Irekhodwe ukusuka malunga ne-150 m ubude kwiPantanal ejikelezwe ziilwandle ukuya kuthi ga kwi-1,200 m eChapada dos Veadeiros. EBrazil iyaziwayo kwiintlanga ezininzi, ukusuka eMinas Gerais neGoiás ukuya kumzantsi-mpuma komzantsi-mpuma, apho ikhula ecaleni kweendawo zokuhlambela amanzi acocekileyo eziveliswa phakathi kweenduli zegrabile kwixesha lonyaka oshushu. Ihlala apho iinyanga ezishushu nezimanzi zihlukile kakhulu.

Ubungakanani obuqolileyo: I-rosette ihlala i-1-2 cm ngaphaya (ifike kwi-4.5 cm); iinwele zeentyatyambo zihlala ziyi-5-8 cm

Izinga lokuKhula: I-Fixed

Uhlobo lomgibe: Flypaper Trap

Like other sundews, the leaves carry stalked glands whose sticky drops of mucilage attract and hold small insects. The glands then secrete enzymes that digest the prey, and the leaf absorbs the nutrients.

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.

Umthandi weentyatyambo waseFransi uAuguste de Saint-Hilaire wafumanisa i-Drosera sessilifolia eMpuma yeMinas Gerais, eBrazil, ecaleni komlambo iSão Francisco, wachaza ngo-1824. UGeorge Bentham wachaza i-Drosera dentata eGuyana ngo-1842, kwaye uLudwig Diels wayikhupha ibe yigama elifanayo le-D. sessilifolia kwincwadi yakhe yonyaka ka-1906 yeDroseraceae. Ngo-1996 umthandi weentyatyambo waseBrazil uFernando Rivadavia wachaza ukufumanisa ukuba ikhula elwandle emva nje kweentlanganiso ezininzi, kuba izityalo zazisele zifa emva kwexesha elibandayo.
