Pedicularis

Pedicularis is a genus of perennial green root parasite plants currently placed in the family Orobanchaceae (the genus previously having been placed in Scrophulariaceae sensu lato[1]).

Description

Between 350 and 600 species are accepted by different authorities, mostly from the wetter northern temperate zones, as well as from South America. The highest diversity is in eastern Asia, with 352 species accepted in China alone.[2][3]

Taxonomy

The common name lousewort, applied to several species, derives from an old belief that these plants, when ingested, were responsible for lice infestations in livestock.[4][5] The genus name Pedicularis is from the Latin pediculus meaning louse.[6]

Selected species

Pollination

Bombus polaris has an essential role in the pollination of the large zygomorphic flowers of Pedicularis.[8] B. polaris has a special adaption that allows it to work the spikes of Pedicularis from the bottom towards the top.[8]

gollark: Go(lang) = bad.
gollark: ``` [...] MIPS is short for Millions of Instructions Per Second. It is a measure for the computation speed of a processor. Like most such measures, it is more often abused than used properly (it is very difficult to justly compare MIPS for different kinds of computers). BogoMips are Linus's own invention. The linux kernel version 0.99.11 (dated 11 July 1993) needed a timing loop (the time is too short and/or needs to be too exact for a non-busy-loop method of waiting), which must be calibrated to the processor speed of the machine. Hence, the kernel measures at boot time how fast a certain kind of busy loop runs on a computer. "Bogo" comes from "bogus", i.e, something which is a fake. Hence, the BogoMips value gives some indication of the processor speed, but it is way too unscientific to be called anything but BogoMips. The reasons (there are two) it is printed during boot-up is that a) it is slightly useful for debugging and for checking that the computer[’]s caches and turbo button work, and b) Linus loves to chuckle when he sees confused people on the news. [...]```I was wondering what BogoMIPS was, and wikipedia had this.

gollark: I think it's a server thing.
gollark: My slightly newer SomethingOrOther 5000 does too.
