These are 3 large sketches presumably by Lady Jones. Only one has an accompanying description which dates it to 17th March [1790]. This is a pencil sketch of a climbing plant in the Company's Botanical Gardens near Calcutta (Kolkata). The second sketch is in pencil with a single flower in colour but with no annotation. The third sketch is also in pencil with leaves and flower in colour.
Each of these three drawings has been given a reference number used in the Head catalogue, including 025.037, 025.067 and one from the sub-collection of 025.054-025.068 (unidentified but likely 025.057 or 025.066 as the remaining numbers have all been assigned).
