經由解剖鏡檢近半數以上的臺灣產禾本科植物。根據葉片解剖所觀察到的顆綠頊綜合特徵；包括顆綠環束鞘之存在，具較小的脈間細胞數最大値及較短的脈間距。由此綜合特徴預測臺灣產禾草光合作用型式，並初步列出C3和禾草名錄。於檢視的150種中，有109種爲C4型，其它41種爲C3型。此外，各亞科在顋綠環綜合特徴方面的若干特性也随文討論。

Nearly half species in the family Gramineae in Taiwan were examined anatomically. The Kranz syndrome based on leaf blade anatomy is characterized by the presence of Krnnz sheath, the few number of maximum cells count and short interveinal distance. A preliminary checklist of C3 and C4 grasses in Taiwan was presented and determined by the non-Kranz or Kranz syndrome. Of 109 species out of 150 species, were recognized as C4 and the others were assigned as Cs. Some aspects of the above criteria in related to each subfamily were also described and discussed.
