Interested in making an herbarium specimen? There are a few things to keep in mind, and a few materials you’ll need.
Keep in mind:
Be sure you have permission to collect from the place where the plant grows.
An herbarium specimen is mounted on paper which is 11.5″ wide by 16.5″ long — so a specimen can be no bigger than that. If a plant is 5 feet tall, you will have to cut it into segments, each no longer than 16″!
ONLY you know where you collected the plant. Accurate locality information is vital. You, alas, are not famous enough for “my back yard” to be sufficient locality data. Poorly pressed specimens or specimens lacking sufficient information on locality will be rejected by the Curatrix.
Things you’ll need: single folds of newspaper, cut to 16″ in length, one fold for each plant
a pen to write on the newspaper
optional but handy: a trowel, and perhaps a set of garden shears / scissors (depending on size of plant) 2 pieces of corrugated cardboard per plant specimen, the cardboard cut into rectangles 11″ X 16″
optional but very helpful: foam rubber, cut into rectangles 11″ X 16″
a stack of heavy books (or a plant press with straps)
optional but very helpful: a smart phone which gives latitude/longitude coordinates or has iNaturalist app.
