sedges: first problem

ok, i am struggling a little with some of this, but part of my struggle is my failure to know how to organize my work for all the parts of the problem. i'm also new to sedges.

so maybe i'll just jump in with what i have so far.

i've done reading on sedges vs. grasses, and some are super obvious, and others... not so much. my first day out i encountered this thing that i THINK may be a sedge, but i also can't pin down what sedge it is, and i can't conclusively say it's not a grass. it turns out i have no photo of it, but is spent some hours trying to draw it it's mayyyybe a scirpus?

i had better luck with what is almost certainly a C. lurida:

one male, two female spikelets, plus the achenes are fat and the veining is right.

and then i ran into this thing, which i think is a sedge but i am also not entirely sure it's not a rush.

it's long and thin with round stems, but it's got these teeny little side-mounted spikelets and that fantastic long bract and i went back and forth between Juncus and Schoenoplectus. i still don't know.

and then there was this thing, which i can say with some confidence is C. intumescens

i still haven't analyzed a grass or diagrammed one, but i'm reading some articles about the parts of grasses that i hope will help me tell the difference where it's not glaringly obvious.

that's it for me for now.


it doesn't matter if you get to camp at one or at six. dinner is still at six.

ok, so i've always known the rhyme

sedges have edges, rushes are round;
grasses have joints when the cops aren't around

-or the child-friendly equivalent

grasses have joints all the way to the ground

which works just as good, i guess.

anyway, these days in addition to my usual stuff, i am taking a class in sedges.

because apparently i don't have enough to do.

i'm going to try to post my assignments here, because this is the sort of thing both of you are interested in sometimes.
