Hemipillia cordifolia Lindl. , Gen. Sp. Orch. pl. 296. 1835; Hook. f. , Fl. Brit. Ind. 6: 167. 1890; King et Pantl. in Ann. Bot. Gard. Calcutta 8: 200. pl. 150. 1898.西藏植物志5: 687. 图359(1-4). 1987.
Forests, rocky slopes; 1500-3500 m. SW Sichuan, Taiwan, S Xizang, NW Yunnan [Bhutan, India, Myanmar, Nepal]. This species is undoubtedly closely related to H.cruciata Finet, except that the lip is 3-lobed in the middle and upper part, and the edge has a strip dentate process. However, Lindley ( 1840 ) did not mention that the edge of the lip has a strip dentate process or pubescence in the original description of this species, and Hook.f. ( 1890 ) did not mention this feature of the lip. Only in the description and illustration of King et Pantl. ( 1898 ), it is clear that the lip margin of this species is pubescent ; in the Flora of Tibet, it is recorded that the edge of the lip flap is striped odontoid rather than pilose. The former is observed as pilose under an enlarged microscope, while the latter is observed as strip odontoid under a high-power dissecting microscope. It 's the result of the same thing, observed under different lenses. |
