Ludwigia palustris

Ludwigia palustris is a species of flowering plant in the evening primrose family known by the common names marsh seedbox,[1] Hampshire-purslane[2] and water purslane. Its native distribution is unclear, but includes parts of the Americas; it can be found on most continents and spreads easily to become naturalized. It is also cultivated as an aquarium plant. This is an aquatic or semiaquatic perennial herb which grows in moist to wet to flooded areas. It is sometimes a weed. The species epithet palustris is Latin for "of the marsh" and indicates its common habitat.[3]

Description

The stem is up to half a meter (20 in) long and spreads to form mats on the mud, rooting at nodes in contact with the substrate, or floats ascending in the water. The leaves are oppositely arranged and green to red or purple in color. Solitary flowers appear in leaf axils. They are made up of tiny green sepals and no petals. They yield small capsular fruits containing many minute seeds.

gollark: I'd just like to interject for a moment. What you’re referring to as Monad, is in fact, GNU/Monad, or as I’ve recently taken to calling it, GNU plus Monad. Monad is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Monad”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Monad, and these people are using it, but it is just a part of the system they use. Monad is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Monad is normally used in combination with the GNU operating system: the whole system is basically GNU with Monad added, or GNU/Monad. All the so-called “Monad” distributions are really distributions of GNU/Monad.
