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. Wang China “wart wild rice” spikelet nearly as long as the grain wild rice, but shorter than the wart wild rice. The morphology of the surface micrographs of the inner and the outer crusts (chaffs) were as follows: The saccular processes of “wart wild rice” in China were densely distributed and similar to the wild rice, but the wart wild rice was more sparsely distributed. China “wart wild rice,” the hook hair mostly curved cone: hook hair around the silicon protrusions papillary, the top round and smooth. Warty wild rice and wild rice particles of the hook hair as a bird-shaped; hook hair around the silicon-like protrusions volcano-shaped top with a star-shaped crown. In the above form as the main basis, China “wart wild rice” and the wild rice and wart wild rice are obvious differences in the geographical distribution is also different with the last two sub-species. So, now a new subspecies of Chinese wart wild rice is Oruza meyeriana (Zoll. Et Mor.) Baill. Subsp. Tuberculata W. C. Wu et Y. G. Lu, G. C. Wang
