Machilus minutiloba S. Lee in Act. Phytotax. Sin. 17 (2): 50. Pl. 5. f.5. 1979
小乔木，树皮黑色；除花被裂片两面、叶下面和小枝节上外，各部分无毛。枝黑褐色，当年生、一、二年生枝基部的芽鳞疤痕形成肿大的高约7-10毫米的节，仅当年生枝基部和节有棕色绒毛，皮孔小，散生，椭圆形，纵裂。顶芽球形，除下部几片芽鳞外有棕色绒毛。叶聚生枝梢，长椭圆形，长6-10厘米，宽1.5-2.8厘米，先端钝，基部楔形，革质，下面有微柔毛，在放大镜下可见，中脉上面稍凹下，下面明显凸起，侧脉纤细，在两面上稍浮凸，每边10-12(24）条，小脉纤细，结成细密网状，叶柄纤细，长8-12毫米。花未见。果序圆锥状，在当年生枝下端腋生，长5.5-9.5厘米，约在中部分枝；果扁球形，未熟时绿色，干后变黑色，直径约1.2厘米，宿存花被裂片部分脱落，因而显得较小；果梗纤细，长6-8毫米。果期6月。
产浙江东南部（乐清的雁荡山）。生山上房屋边。

Persea minutiloba (S. K. Lee) Kostermans.
Small trees. Branchlets blackish brown with small elliptic lenticels, glabrous, conspicuously swollen and densely brown tomentose at nodes. Terminal buds almost brown tomentose. Leaves clustered at apex of branchlet; petiole slender, 8-12 mm; leaf blade oblong, 6-10 × 1.5-2.8 cm, leathery, abaxially puberulent, midrib conspicuously elevated abaxially, slightly concave adaxially, lateral veins slender, 10-14 pairs, veinlets slender, densely reticulate, base cuneate, apex obtuse. Flowers unknown. Infructescences paniculate, at lower part of current year branchlet, 5.5-9.5 cm, branched at middle of peduncle. Fruit compressed globose, ca. 1.2 cm in diam.; persistent perianth lobes oblong, gray appressed pubescent on both surfaces; fruiting pedicel slender, 6-8 mm. Fr. Jun.
● Mixed forests on mountain slopes. SE Zhejiang (Yandang Shan).
