Description
Cormus composed of large, irregular and loosely anastomosed tubes. Water-collecting tubes converge to form conical projections with an osculum. The surface of the tubes is hispid because of the presence of diactines and trichoxea. Cells with granules have not been observed. The skeleton comprises equiangular and equiradiate triactines and very few tetractines. Actines are conical and straight, with a sharp tip. Diactines and fusiform and slightly curved. They are projected towards the exterior of the tubes. Trichoxeas are also present, perpendicular to the surface of the tubes.[2]
gollark: Maybe it'll be practical *eventually*. We've got a-few-nanometres-or-so-accuracy fabrication for silicon stuff.
gollark: It's probably one of those things which could be very nice if you could actually make it at all somehow.
gollark: Fair. Maybe there's a gap in the market for better online teaching of this stuff, somehow.
gollark: It's not like you can't learn stuff school doesn't cover, though.
gollark: I'm looking at the AQA one here, as my school seems to have arbitrarily chosen that.
