永安天宝岩自然保护区是我国中亚热带森林生态系统自然保护区之一，该区种子植物150 科579 属1 281种及变种、变型。

Asian (47.4%) and temperate genera mainly constituted by North temperate (50%) and E. Asian (50%). So that the geographical elements are discomplex. In the 25 species of arborous layer, 76% is the middle subtropical zonal type, 16% south subtropical zonal type and 8% north subtropical zonal type, of which the first 6 positions of important value index were all middle subtropical zonal type. This showed that the community was subtropical characteristic. There are 59.5% evergreen and 40.5% deblade of 79 known species in which the mid-phaenerophytes is the first position of all, accounting for 27.8%, and the evergreen broad-leaved species constituted the majority of meso-phaenerophytes which accounts for 15.2%.

乔木层多数优势种为稳定型种群，所以乔木层优势区系成分相当稳定，表明该群落为一种顶极群落。59个种子植物属只有10个分布区类型和4个变型，地理成分不复杂，其中热带分布27属占46.6%，温带分布31属占53.4%；热带分布以泛热带和热带亚洲分布为主，分别占52.6%和47.4%，温带分布为北温带和东亚分布各占50%。25个乔木层树种中，中亚热带地理分布类型的占76%，南亚热带地理分布类型的占16%，北亚热带地理分布类型占8%，重要值指数排列前6名的均为中亚热带地理分布类型，所以该群落为亚热带性质。

Based on Weed Flora of China, this paper analyzed the character of the areal types on seed weeds in China.

在《中国杂草志》记载的基础上，分析了中国种子植物杂草科和属的区系特征。

Fourier Transform Infrared and Horizontal Attenuated Total Reflectance techniques were used to obtain the FTIR of semen cuscutae (the seed from Cuscuta chinensis lam) and Japanese dodder seed (the seed from Cuscuta japonica Choisy). The similar features between the semen cuscutae and Japanese dodder seed are extracted by continuous wavelet transform.
