Mesembryanthemum testiculare Possibly 1777 - 1786

This is a study of Mesembryanthemum testiculare, made with pen and watercolour by Robert Jacob Gordon. The composition is dominated by the symmetrical arrangement of the succulent plants across the horizontal axis. Each component is rendered with careful attention to botanical detail. Gordon’s approach is characterized by a descriptive linearity, with the delicate use of watercolour washes adding depth and volume. The fleshy, heart-shaped leaves are painted with varying shades of green, while the flowers display complex layers of pink and purple, drawing our eye to the floral structures. The roots, depicted with earthy tones, contrast with the lighter background, creating a sense of depth and grounding. The plants are isolated against the white space of the paper, allowing us to focus on the individual characteristics of the specimen. Note how the artist uses line and colour not only to document but also to highlight the plant's unique form. This reflects the cultural inclination to classify and understand the natural world through visual means.
