Wildcards using '*' are accepted, but must be preceeded by at least 3 characters. For example 'rho*' is accepted, but 'r*' will not be. Only one family may be entered, but more than one genus and/or species may be entered. These should be separated by a comma. For example: 'genus= vella, gilia' Searches are all inclusive, i.e. if you include a family and a genus, you will only get returns that of that genus in that family. Selecting samples for a shopping list generates cookies. These cookies are used if you wish to add more samples from a different query to your list. If you have cookies disabled on your computer, you will not be able to use this facility. However, you will be able to complete the order from the current query. Finally, we do not reccomend searching on family alone, as this can bring back several thousand rows of data, which can be slow to download.
