had my first day of plant systematics today and man. I'm so excited for this class. Day one and I received two pieces of information that blew my socks off in two different ways:

1. We will be going to see Isoetes in the field! and

2. Duckweed (Lemna) is in the freakin' ARACEAE family?!?!? Yknow. Corpse flower and skunk cabbage? Calla lily? Thermogenesis? Stinky? LARGE and in charge? And this is why morphological classification is on such thin fuckin ice. Man. I'm reeling. I love learning new things about plants because they will ALWAYS surprise me.

OUGH ISOETES

[botanyshitposts]

Scientists just figured out how plants adapted to live on land! Heres the article, I thought youd want to read it right away! As soon as I saw it I came here. http://sulc.us/plantxylem

ahhhh see, this is some juicy plant lore! it's specifically talking about the shape of the xylem in plant stems.

it's interesting the balance that has to happen here. we want a lot of small straws (xylem cells, used by plants to pull water up from the roots to the leaves) to suck water up the stem as opposed to a few big ones because any air that gets into a straw breaks the flow of water and makes it impossible to get it back, and that's both more likely to happen and more impactful if we use a few big straws over many small ones-- but at the same time, cramming a bunch of small straws together also isn't enough to fix the problem, because if too many small straws are touching each other at once, any air that gets into one can spread to all the ones around it. so the solution is to spread a bunch of small straws out in increasingly complicated patterns to maximize the number of small straws and minimize the number of other straws each is touching! very clever.

also, side note, they include isoetes in this and like, im gonna have to look into it more but it LOOKS like the Guys just.... thickened the walls of the straws and left it instead of trying to make a new shape?? i assume this works because they were going to be incredibly small and aquatic anyway, so there was no real reason to bother if their straws are already incredibly tiny and dont need to carry much water very far to begin with, but it IS interesting considering that the main driver of isoetes evolution is currently suspected to be drought caused by the continents splitting. plants that make you go hmm moment for sure

Isoetes velata

I've loved quillworts since i learned of thier existence but I've only just learned of tumblrs love of quillworts, they are hard to photograph, I have a degree in Fine Art and 2 weeks from a degree in Conservation Biology and I'm the defacto bryologist of my state* They are hard to photograph, at least in my state , the 9 species in WA overlap alot in habitat and morphology, despite destinct spore ornamentations. *Dm if u disagree I need someone who cares abt moss to talk to

I'm over here watching everyone freak out over Chuck Tingle coming to Tumblr like bold of you to assume the Tingle has not been here all along camouflaged like an isoetes in the tumblr swamp.

JUST FOUND THE ISOETES IN MY SCHOOLS GREENHOUSE AND NEARLY ATE SHIT CAUSE I STARTED JUMPING AROUND ON THE WET CONCRETE FLOOR

[thebashfulbotanist]

My sister, the student who is the “other half” of this blog, tells me that these are semiaquatic Isoetes quillworts, and that their genus evolved in the Jurassic period. Apparently, @botanyshitposts is fond of this one :) I’m just fond of touring the conservatory at night before Halloween!

on behalf of isoetes I’m offended, Mr. Senator.
