Manual of the Grasses of the United States (Hitchcock & Chase, 1950) p711

"... find an organism, any organism, small, large, gaudy, subtle — anywhere, and they are everywhere — and get a sense of it, its shape, color, size, feel, smell, sound.... Then find a name for it. Learn science’s name, one of countless folk names, or make up your own. To do so is to change everything, including yourself. Because once you start noticing organisms, once you have a name for particular beasts, birds and flowers, you can’t help seeing life and the order in it, just where it has always been, all around you." — Carol Kaesuk Yoon, Reviving the Lost Art of Naming the World

If a search such as "Carex leptalea var. leptalea" doesn't deliver the results you want, try "Carex leptalea".
Or, to minimize chances of a misspelling, try just "Carex le".

Less is more: If "pencil flower" doesn't deliver the results you want, try "pencil".
Or try alternate spellings: If "wooly" doesn't work, try "woolly" or just "wool".
