The descriptions should be clear... if you understand the terminology.
I would think a book would have a grass diagram... but maybe your's doesn't?
So, here are 2 I grabbed from Google that look pretty clear:
To help remember stuff..
the biggest categories are if your grass has rhizomes (rhizomes run under ground), stolons (stolons stay on top of the ground), or neither.
After that:
the auricles are like auditory.. the ears there where the blade comes off the collar. Lack of auricles, and what they look like help narrow down grasses.
Also... there are some things that look like grasses and are not... like sedges (sedges usually have edges, the stem when dissected is triangular).
Next fall you can seed with white ball clover and rye grass. There is small grain rye, think rye bread, and rye as a grass. You want the rye grass. The rye grass mixed with the clover helps to keep bloat down, plus keep baking soda out for the sheep free choice. You will have to keep them off the pasture until March, to let the rye and clover grow. Then feed them hay, let them graze for a couple of hours, call them back to the barn with a little feed. You can lengthen the time every 2 days.
@Alaskan The guides do have the picture and the grass description list "no auricles, etc". My problem is visualizing all the various changes overlaid on one piece of grass.
I'm used to reading mechanical diagrams where everything is as shown. And labeled like these.
What I will probably end up doing is make my own drawing for each grass as I figure them out in this style.
