Some researchers believe that the latter area possesses savanna vegetation. Savannas are closely associated with seasonal drought, and they may be defined by climatic climax vegetation in tropical and subtropical areas. Based on the ecoclimatic analyses as well as the surviving vegetation in Taiwan, we inferred that the potential natural vegetations of these 2 semi-arid regions were not savanna but forest with some drought-deciduous trees. In conclusion, the physiognomic type of grassland dotted with trees may occur in small areas at present, but Taiwan lacks climate-shaped savanna climax vegetation.

本研究将疏林定义为分布於热带及亚热带之气候形塑的极相植群，气候分析结果表明台湾半乾旱区域之缺水逆境并不严重，再配合现生残存植群之观察，发现台湾有形相为疏林的现生局部性植群，但其潜在自然植群应为参杂有乾旱落叶之阔叶树种的森林，并不存在较大面积之潜在的气候型极相疏林。

At last of the paper, it's studied the relationship between the resistance of the pins of the pincushion 2D PSD and Gear theorem, and find the way to get the boundary resistance and square resistance of sensitive area from the resistance of the pins which can get the position nonlinearity rapidly.

Both upper and lower epidermis cells are polygonal or irregular in shape in all species studied. The patterns of anticlinal walls are straight, arched or sinuous, and the raphal cuticular striastriae are occasionally observed on periclinal walls. Stomatal apparatus and secretory cells are found on the upper epidermis of several species and on the lower epidermis of all Species. The slomata apparatus mainly belong to the paracytic type and latercylic type; rarely anomocytic type occurs along with the paracytic one.
