中国“疣粒野稻”拉丁学名和中名的订正

A Revision on the Scientific and Chinese Name of the Verrucose Wild Rice Indigenous to China

中国“疣粒野稻”的小穗近等长于颗粒野稻,而短于疣粒野稻。内外稃(谷壳)表面电镜扫描形态是:中国“疣粒野稻”的山形瘤状突起分布较密,与颗粒野稻近似,但疣粒野稻则分布较疏。中国“疣粒野稻“的钩毛多为弯锥形:钩毛周围的硅质突起为乳头状,顶端圆而光滑。疣粒野稻和颗粒野稻的钩毛为雀嘴形;钩毛周围的硅质突起为火山顶状,顶端具星状冠。以上述形态为主要依据,中国“疣粒野稻”与颗粒野稻和疣粒野稻均有明显区别;在地理分布方面也与上二亚种不同。所以,现将中国“疣粒野稻”另立一新亚种,为瘤粒野稻Oruza meyeriana (Zoll. et Mor.)Baill. subsp. tuberculata W. C. Wu et Y. G. Lu, G. C.

The morphological characteristics observed by SEM on the surface of the lemma and palea are as follows: The hillformed tubercles of Chinese verlUCOSe wild ricegrow densely similar to granudated wild rice while those of the verrucose wild rice outside China is sparsely. The glochid of Chinese verrucose wild rice is cuiviawl-shaped; Around the glochid the silica tubercles which have glossy ○-shaped tops are papillae. The glochid of granulated and ven-ucose wild rice outside China is rostriform and the silica tubercle takes after a volcanic top covered by a star-cap. It is obviously that Chinese verrucose wild rice is different from both the granulated and verrucose wild rice. In addition, the geographic distribution is different too. Therefore. Chinese verrucose wild rice is a new subspecies, i.e. Oryza meyerian(Zoll, et Mor. ) Baill. subsp, tuberculatu W. C. Wu et Y. G. Lu, G. C. Wang.
