C418533E0B14FF9BFF6A771E12193EEC.taxon	diagnosis	Diagnosis: — Ilex calcicola is similar to I. mamillata C. Y. Wu ex C. J. Tseng (1984: 413) and I. wuana T. R. Dudley (1988: 14), but differs from I. calcicola in having (1 –) 5 – 8 (– 10) - fruits per fascicle, the 6 - merous flowers, the shape and size of leaves and the puberulent surface of leaves (Table 1).	en	Xu, Kewang, Shi, Xianggang, Fan, Qiang, Xu, Weibin, Liao, Wenbo (2017): Ilex calcicola (Aquifoliaceae), a new species from a limestone area of Guangxi, China.

C418533E0B14FF9BFF6A771E12193EEC.taxon	description	Shrubs or trees evergreen, 10 m tall. Bark pale grey. Current year’s branchlets green, slender, puberulent, with gray rounded or elliptic lenticels; second year’s branchlets gray, subterete, with dense brownish lenticels. Terminal buds densely puberulent, conic. Petiole 5 – 11 mm, ca. 1 mm in diameter, puberulent, abaxially rugose, adaxially narrowly sulcate. Leaves persist one – three years on branchlets. Leaf blade narrowly elliptic, elliptic, or obovate-elliptic, rarely obovate, (3.5 –) 5.2 – 8.5 (– 11.5) × (1.0 –) 1.7 – 3.5 (– 3.8) cm, leathery, pubescent abaxially, inconspicuously and minutely glandular punctate, midvein adaxially impressed, minutely pubescent, abaxially keeled, densely puberulent, with 5 – 10 pairs of lateral veins, obscure adaxially, conspicuously elevated abaxially, and reticulate veins obscure adaxially, obvious abaxially; leaf base cuneate or subrounded; leaf margin entire, apex acuminate, rarely acute. Male inflorescences: cymes (1 –) 3 – 6 - flowered, fasciculate, axillary on current year’s branchlets or on leaf scars of second or third year’s; peduncles (1 –) 2 – 4 mm; pedicels (1.5 –) 4 – 8 mm, densely puberulent; bracteoles basal, deltoid, puberulent; flowers 6 - merous; calyx patelliform, 6 - lobed, lobes deltoid-ovate, ca. 0.6 mm long, ca. 0.8 mm wide at base, papery, puberulent, ciliate; petals 6, white, broadly oblong, ca. 3 mm long, basally slightly connate; stamens ca. as long as petals; rudimentary ovary ovoid. Female inflorescence: cyme 1 (– 2) - flowered, fasciculate, rarely solitary; bracts triangular, ciliate; pedicels 4 – 7 mm long, densely puberulent, with 2 lanceolate ciliate sub-basal bracteoles (prophylls); calyx and corolla as in the staminate flowers; staminodes slightly shorter than petals; sterile anthers triangular, ca. 0.6 mm long, ca. 0.4 mm wide at base; ovary ovoid, ca. 2.5 mm in diameter; persistent stigma mammilliform, cylindric. Infructescences: 1 - fruited cymes (rarely 2 - fruited cymes), fasciculate, fascicles (1 –) 5 – 8 (– 10) - fruited, axillary; fruiting pedicels 3 – 6 mm, puberulent; persistent bracteoles basal, deltoid, puberulent. Fruit red, globose, ca. 4 mm in diameter; persistent calyx 6 - lobed, lobes broadly deltoid, puberulent, ciliate; persistent stigma mammilliform or cylindric; pyrenes 6, ellipsoidal, ca. 3 mm long, ca. 1 mm in diameter, abaxially longitudinally 3 - striate and 2 - sulcate, laterally 4 - striate and 3 - sulcate, endocarp leathery. Pollen and stomata morphology: — The pollen grains of I. calcicola are tricolpate. Polar axis (P) is ca. 23.08 μm, equatorial axils (E) is ca. 10.83 μm. The exine is ornamented with conspicuous gemmae and clavae of variable size (Fig. 4 A, 4 B, 4 C). The stomatal type (Fig. 4 D, 4 E) of this new species is amphicyclocytic, which is the most common and basic type of Ilex (Li et al. 2010). The mean density of stomata is ca. 0.05 per 1 μm 2 (Fig. 3 D). The mean size of the normal stomata is 26.32 × 22.63 μm. The hairs of the new species (Fig. 4 F) is short and soft.	en	Xu, Kewang, Shi, Xianggang, Fan, Qiang, Xu, Weibin, Liao, Wenbo (2017): Ilex calcicola (Aquifoliaceae), a new species from a limestone area of Guangxi, China.
