85 accessions

Other

Material the evidence places outside the four classes: botanic-garden and research-station plants, named varieties and seed sent from elsewhere.

583 accessions

Unknown

Accessions whose evidence does not decide a class, most of them herbarium sheets whose labels give no habitat or cultivation statement.
