Description

The leaves are divided into often asymmetrical leaflets which are subdivided into lobed segments, the leaf measuring 3 to 20 centimeters in total length, not counting the long, brown petiole. It is hairless and lacks scales. The leaf is covered in grainy exudate known as farina.

Chemotypes

The fern comes in two chemotypes which can be distinguished by the color of the farina, white or yellow, and the two are rarely found growing together.[1] The two chemotypes are sometimes treated as subspecies.[1]

Subspecies
gollark: But there are... less bad ones?
gollark: Yes, I'm aware, I wrote a blog post about this thus I am an expert.
gollark: There are cheapish somewhat ruggedized phones available now, which is neat because I drop my phone a lot, subject it to water sometimes by accident, sort of thing, but they seem annoying to repair and have mediatek chipsets.
gollark: Oneplus 5s are apparently not too horrible to replace batteries in, and not terribly expensive I guess.
gollark: Well, nonremovable, it may be *replaceable* with some tools, although on some evil devices you need to literally unglue the screen or something.
