The identification of materials is of utmost importance before a repair may be started. There are several generalities we can use, and samples may be sent  for identification.

To identify a round sample 

If it is smooth, it is probably round reed, this is ordered by the millimeter measurement -remember that paint or a finish will add bulk.
If it is made of paper, it is fiber rush, and is available in many sizes. If the paper has a wire core, this is a supporting spoke and is wire core fiber rush.
If the sample appears to taper, and has small rough spots it may be willow. There are many different sizes, and processes used to prepare willow, so it may not always appear the same.
If the round piece has a hard natural finish, with regular joints, This may be Rattan with the natural bark left on.
On occasion bamboo is used. Bamboo has regular nodes with a smooth hard surface and is hollow. If the piece is 3/8" or larger it may be reed, or rattan, bamboo, or possibly even a wooden dowel.  footage chart

To identify a half round sample 

Half round is as if you took a round piece of stock, and cut it in half. If it is smooth on the rounded part, it is probably  half round reed, this is ordered by the millimeter measurement.
If the sample appears to taper, and has small rough spots it may be split willow.
If the piece is 3/8" or larger this will be reed, or rattan.
If used as a structural support, it may be wood. Split Bamboo is also used, this would be in all sizes, and appear hollow.  footage chart

To identify a flat sample   

If it is fairly smooth and flat on both sides, it is probably flat reed, this is ordered by the inch increment.
If it is made of paper, it is just that, a  flat fiber paper.  footage chart

To identify a flat oval sample   

A flat oval weaver or wrap is flat on one side and has a graceful oval on the exposed surface.
If it is smooth on the rounded part, it is probably  flat oval reed, this is also ordered by the millimeter or inch increment.
If it is smooth on the rounded part, and has a hard natural finish, and rough spots on occasion it is probably binder cane, or cane this is also ordered by the millimeter.  footage chart

Braiding

This may be round reed or  fiber rush. The width of the braid is controlled by the number of strands, or the size of material used. We do have  fiber braid. There is braiding how-to in our wicker repair pamplet. view
