Description

Bulbophyllum boonjee is an epiphytic herb with crowded, flattened, pale green pseudobulbs 4–8 mm (0.2–0.3 in) long and 3–5 mm (0.12–0.20 in) wide. Each pseudobulb has a single stiff, pale green leaf, 15–40 mm (0.6–2 in) long and 3–4 mm (0.12–0.16 in) wide. Between two and four bell-shaped maroon flowers with darker stripes, 4–5 mm (0.16–0.20 in) long and 6–7 mm (0.24–0.28 in) wide are arranged on a thread-like flowering stem 10–15 mm (0.39–0.59 in) long. The dorsal sepal is 3–4 mm (0.1–0.2 in) long and 1–2 mm (0.039–0.079 in) wide, the lateral sepals a similar length but twice as wide. The petals are 2–3 mm (0.079–0.12 in) long and 1–2 mm (0.039–0.079 in) wide. The labellum is about 2.5 mm (0.098 in) long and less than 1 mm (0.039 in) wide, and curved with small lumps on the upper surface. Flowering occurs between September and February.[2][3]
