The ‘large leaves group’: morphological comparison between Uvariopsisbakeriana, Uvariopsiscitrata, Uvariopsiskorupensis and Uvariopsissubmontana. In bold: character useful to differentiate the species. l:w = length:width.

	Lamina	Flower pedicel	Sepals	Petals	Altitudinal range
Uvariopsisbakeriana	150–340 mm long	2–8 mm long	Male and female flowers: 1–3.5 mm long, 1.5–3 mm wide, free	Male and female flowers: l:w ratio 4–10, narrowly ovate to linear, free, valvate, bright pink to dark pinkish red	50–800 m above sea level
Uvariopsiscitrata	312–500 mm long, strong lemon scent when crushed	0–2 mm long	Male and female flowers: 9–15 mm long, 4–6 mm wide, basely fused	Male and female flowers: l:w ratio ca. 3.5, ovate, greenish yellow	60–300 m above sea level
Uvariopsiskorupensis	280–615 mm long	6–70 mm long	Male flowers: 1–5 (7.5) mm long, 2–6.5 mm wide, basely fused	Male flowers: l:w ratio 2.5–7, narrowly ovate, fused at base	90–160 m above sea level
			Female flowers: 3–5 mm long, 4–5 mm wide, basely fused	Female flowers: petals more than 3 times longer than the sepals, l:w ratio 7–12, narrowly ovate, fused at base, cream to pinkish
