Characters used in the key:
The following characters are stored in the database.
Not all characters are searchable, nor are all fields populated for all grasses,
either because the field is not relevant to an individual grass (such as spike shape
for a branched grass) or because data are not known for that grass (such as for leaf blade
length or branch length). In this case, we are updating this information as and when it
becomes available. These fields are not searchable on the entry page, but they are
available on the refined search page and displayed for comparison in descriptions.
