This work shows sophisticated brushwork with edged lines depicting hibiscus. Lines of regular script with various gradation of ink outline the leaves and petals. The flower extends from the left with leaves sketched using a small brush and thick ink. The variation of brushwork forms lines with a variety of thickness, depicting leaves of different sizes. Slender twigs were outlined using Tang-style gongbi and rhythmic strokes. Such brushwork suggests Pu Hsin-yu’s use of calligraphic strokes on paintings, thereby depicting his personality. Gradations of ink forms light and shadow of the leaves, reflecting the scholarly character of the artist. Light ink and thin strokes were used to depict the flower of light colour, enhancing the purity of the subject and the austere personality of the artist. Dense ink was used on the rocks emerging from the water, depicting its rough surface. This rare outline depiction contrasts with Pu’s usual boneless strokes in flowers. This painting shows reference to Tang Yin’s work and the scholarly character of Song paintings.
