Genlisea margaretae is a carnivorous species from the genus of trap traps ( Genlisea ). It is native to Africa and has the smallest known genome of any bedspread.

description

Genlisea margaretae is a perennial herbaceous plant . The numerous, bare leaves standing in a dense, native rosette are 20 to 30 millimeters long and 3 to 4 millimeters wide, spatulate and blunt at the end. The numerous traps are 6 to 150, rarely up to 200 millimeters long. On the 10 to 35, rarely up to 50 cm high inflorescences, there are six to ten purple to mauve flowers , the lower lip of which usually appears yellowish.

The number of chromosomes is given as 2n = about 40. At 63.4 Mbp, the species has the smallest known genome of all bedspreads .

distribution

Genlisea margaretae is native to Africa ( Zambia , Madagascar and Tanzania ) on moss cushions in permanently moist moors and in trickled seepage on island mountains .

Systematics and research history

Genlisea margaretae was first described by John Hutchinson in 1946 , it is placed in the subgenus Genlisea .

In addition to Genlisae violacea and Genlisea aurea , Genlisea margaretae was one of the three species in which the long suspected carnivory of the genus was detected in 1998 .
