Note: floral characters of genera of Lauraceae extracted mainly from Rohwer [2]; Hypodaphnis was examined by J.G.Rohwer (vouchers: Leeuwenberg 5557, Wilks 1655, Zenker 3033a in HBG); Sinopora is according to Li et al. [36]; Yasunia is from van der Werff & Nishida [37]; Damburneya is from Trofimov et al. [38]
