==Description==
 
−
Herbs 25–80 cm tall. Rhizome compact, sometimes long-creeping, 2–5 mm in diam. Leaves basal and cauline, usually trifoliolate or occasionally unifoliolate; leaflets of trifoliolate leaves narrowly ovate to lanceolate, 3–18 × 1.5–7 cm, apex long acuminate, base cordate with lobes rounded or acute, those of the lateral leaflets very unequal; unifoliolate leaves ovate or broadly ovate, 8.7–20 × 6.8–11.5 cm, apex acuminate, base cordate with lobes equal, rounded or rarely acute; leaves leathery when mature, margin spinous-serrate with the spines 1–2 mm long, adaxially deep green, glossy, abaxially glaucous, papillose, with dense or sparse short appressed stout bristle-like hairs and sometimes densely sericeous. Flowering stem usually bearing 2 opposite trifoliolate leaves, less often with 3 whorled trifoliolate leaves or 2 opposite unifoliolate leaves, rarely with 2 opposite leaves with one trifoliolate and the other unifoliolate or 3 whorled unifoliolate leaves. Inflorescence compound with lower peduncles 2–5-flowered, loose few- or many-(10–55)-flowered, glabrous or occasionally glandular hairy; pedicels 1–4 cm. Flowers 3–5 cm in diam., yellow, rose-purple, pale violet, or white. Outer sepals blunt, outer pair ovate-oblong, ca. 3 × 2 mm, inner pair broadly obovate, ca. 4.5 × 4 mm. Inner sepals ovate-elliptic, 8–12 × 3–7 mm, apex acute. Petals much longer than inner sepals, horn-shaped, tapering from the swollen but lamina-less base, curving outwards, 1.5–2.5 cm. Stamens 3–4 mm; anthers yellow or green, ca. 2.5 mm, pollen yellow or green. Capsules ca. 2 cm.

==Distribution and habitat==
 
−
''{{Taxon name|Epimedium acuminatum}}'' is widely distributed in Sichuan, Chongqing, Guizhou, and northern Yunnan. It usually occurs in forests, thickets, bamboo forests, and weedy slopes ranging from 270 to 2400 m in elevation.

==Phenology==
 
−
''{{Taxon name|Epimedium acuminatum}}'' flowers from April to May, and fruits from May to June.

−
==IUCN Red List category==
 
−
Although ''{{Taxon name|Epimedium acuminatum}}'' has a relatively wide distribution in China; it should be designated as Vulnerable (VU) (IUCN 2013<ref name="B3">IUCN (2013) The IUCN red list of threatened species, version 2013.9. IUCN Red List Unit, Cambridge, U.K. [http://www.iucnredlist.org/ http://www.iucnredlist.org/] [accessed: 6 June 2014]</ref >), because of exploitation for medicinal use, especially in Guizhou.

==Notes==
 
−
''{{Taxon name|Epimedium acuminatum}}'' is one of the most widespread species in the genus, and exhibits much variation in morphology; therefore, it is not surprising that there are several synonyms associated with it. Léveillé (1909)<ref name="B4">{{aut|Léveillé H}} (1909) Decades plantarum novarum, XXIII. Repertorium Specierum Novarum Regni Vegetabilis 7: 257–259. doi: 10.1002/fedr.19090071605</ref > published ''{{Taxon name|Epimedium komarovii}}'' H. Lév. upon only contrasting it with ''{{Taxon name|Epimedium sagittatum}}'' Maxim., Stearn (1938)<ref name="B5">{{aut|Stearn W}} (1938) ''{{Taxon name|Epimedium}}'' and ''{{Taxon name|Vancouveria}}'' ({{Taxon name|Berberidaceae}}), a monograph. Botanical Journal of the Linnean Society 51: 409–555. doi: 10.1111/j.1095-8339.1937.tb01914.x</ref > found that it was not distinct from ''{{Taxon name|Epimedium acuminatum}}'' and reduced it into synonymy. ''{{Taxon name|Epimedium simplicifolium}}'' T.S. Ying was described by Ying (1975)<ref name="B10">{{aut|Ying T}} (1975) On the Chinese species of ''{{Taxon name|Epimedium}}'' L. Acta Phytotaxonomica Sinica 13(2): 49–56.</ref >, only separating it from ''{{Taxon name|Epimedium acuminatum}}'' in having unifoliolate, sericeous leaves. Upon extensive specimen examination, however, Zhang et al. (2011)<ref name="B13">{{aut|Zhang Y}}, {{aut|Wang Y}}, {{aut|Li X}}, {{aut|Li J}} (2011) A taxonomic revision of unifoliolate Chinese ''{{Taxon name|Epimedium}}'' L. ({{Taxon name|Berberidaceae}}). Kew Bulletin 66(2): 253–262. doi: 10.1007/s12225-011-9275-y</ref > found that the diagnostic characters of ''{{Taxon name|Epimedium simplicifolium}}'' were within the range of morphological variations of ''{{Taxon name|Epimedium acuminatum}}'' and placed ''{{Taxon name|Epimedium simplicifolium}}'' into synonymy.<br />
 
−
''{{Taxon name|Epimedium chlorandrum}}'' was described by Stearn (1997)<ref name="B7">{{aut|Stearn W}} (1997) Four new Chinese species of ''{{Taxon name|Epimedium}}'' ({{Taxon name|Berberidaceae}}). Kew Bulletin 52(3): 659–669. doi: 10.2307/4110292</ref > as having the inner sepals being slightly ascending, and not closely appressed to the petals, and the anthers and pollen as being green. However, observations from the type locality of ''{{Taxon name|Epimedium chlorandrum}}'' show that the diagnostic character of the inner sepals as not closely appressed to the petals is not stable, and ''{{Taxon name|Epimedium acuminatum}}'' is also found having inner sepals being slightly ascending, with green anthers and pollen. There is no difference in morphology for the two species, thus, ''{{Taxon name|Epimedium chlorandrum}}'' is here treated as a new synonym of ''{{Taxon name|Epimedium acuminatum}}''. Additionally, extensive specimen examination and field investigation demonstrate that it is incorrect for Stearn (1997)<ref name="B7">{{aut|Stearn W}} (1997) Four new Chinese species of ''{{Taxon name|Epimedium}}'' ({{Taxon name|Berberidaceae}}). Kew Bulletin 52(3): 659–669. doi: 10.2307/4110292</ref > to recognize the color of anther and pollen as diagnostic features in ''{{Taxon name|Epimedium}}'' because, besides ''{{Taxon name|Epimedium acuminatum}}'', other ''{{Taxon name|Epimedium}}'' species (e.g. ''{{Taxon name|Epimedium sagittatum}}'', ''{{Taxon name|Epimedium sutchuenense}}'' Franch., ''{{Taxon name|Epimedium elongatum}}'' Kom., and ''{{Taxon name|Epimedium leptorrhizum}}'' Stearn) with yellow anthers and pollen are also found with green anthers and pollen.
