 The Institute has changed little since its founding, and is of interest to historians as well as botanists.It contains the original library with an extensive collection of botanical books, monographs and journals and herbarium with a collection of dried, pressed plants from Britain and Europe, mounted on sheets accompanied by collecting details, to help members name or identify plants correctly.The lecture room was renovated and restored in 2015, including some unique wallpaper designed by Augusta Ackerman.
