Senecio inaequidens DC. and Sporobolus tenuissimus (Mart. ex Schrank) Kuntze were recently found in southern part of Taiwan. Senecio inaequidens occurred at middle-altitude mountain area, and Sporobolus tenuissimus was found at plain and low-altitude mountain area. The present study offered the taxonomic description, photographs and illustrations o...

We clear up a taxonomic and nomenclatural confusion, in which Senecio lancifer (Asteraceae, Senecioneae) has been involved. This name is determined to belong to a Ligularia species, which is identical with L. leesicotal. The correct name of the species is L. lancifera (Drummond) Srivastava & Jeffrey.

In its current circumscription, Senecio ser. Culcitium Cabrera, which includes ca. 40 South American species, is characterized by discoid, sometimes nodding capitula, calycular bracts resembling a multiseriate involucre, and style branches api-cally truncate with a ring of penicillate collecting hairs. The phylogenetic relationships of Senecio ser....

... To study the patterns of plant invasions, naturalized plants are often employed since naturalization implies successful reproduction and dispersal in newly colonized territories (Rejmánek and Richardson, 1996; Richardson et al., 2000; Daehler, 2001; Pyšek et al., 2002; Wu et al., 2003; Lake and Leishman, 2004; Pyšek et al., 2004). In Taiwan, the patterns of naturalized flora were first compiled and examined in 2002 (Wu et al., 2004a, b); however, the naturalized flora has subsequently almost doubled during the past six years (Chen et al., 2004, 2005, 2006, 2007; Hsu et al., 2004, 2005, 2006; Jung et al., 2005, 2006, 2008). This remarkable number of recent naturalizations, approximately 50 species per year, seemed to imply escalating plant invasions in Taiwan. ...

Naturalized flora of Taiwan has been increasing in the past six after the first catalogue was compiled in 2002. In order to probe into the increasing pattern behind this dramatic growth of potential invaders, we compiled and evaluated newly added naturalized species in a quest for better understanding. Furthermore, naturalized species shared with neighboring regions, such as Mainland China and Japan, were estimated as well. The results revealed that two-thirds of these newly recruited species naturalized before 2002, and only 77 actually naturalized after 2002. The proportion of naturalized flora in the native species pool increased from 8% to 12%. The compositions, origins, and life forms of these potential invaders before and after 2002 were similar with slight fluctuations presented in the ranks of the dominant families. Number of species shared with neighboring regions multiplied due to the fast growth of the naturalized flora in Taiwan; nevertheless, the number might be understated due to the inaccessibility of the latest naturalized floras from neighboring regions. The doubled flora of naturalized species in the past six years implies insufficient attention to plant invasions and lag phases of invasion. The expansion of naturalized flora in Taiwan also increased the pools of naturalized species shared with neighboring areas, including Mainland China and Japan.
... Reports on new naturalizations have increased rapidly in the past few decades, as attested by publications in recent issues of the journal Taiwania. In the past several years, the Sunflower family (Asteraceae) has become the major contributor to the invasive flora in Taiwan (Jung et al., 2005;Wu and Wang, 2005;Chen and Wu, 2006;Hsu et al., 2006;Jung et al., 2006;Wang and Chen, 2006;Chung et al., 2008;Jung et al., 2008;Tseng et al., 2008aTseng et al., , 2008bTseng et al., , 2008c, surpassing the legume family that ranked first in earlier reports (Wu et al., 2004a;Wu and Wang, 2005;Peng and Yang, 2008). In this article, we report yet another apparently invasive alien species of Asteraceae, Emilia praetermissa, to our naturalized flora. ...

Emilia praetermissa (Asteraceae), first collected in 1997 in Keelung, has become naturalized in Taiwan and is now a frequent sight in northern part of the island. This species has often been misidentified as Emilia fosbergii, another alien Emilia species commonly seen in central and southern Taiwan. Detailed description, report of chromosome number (2n = 20) and karyotype with a review of relevant cytological literature and a distribution map are provided. Line-drawings as well as color photographs of E. praetermissa and its congeners occurring in Taiwan are presented to aid in identification.
... Asteraceae, one of the largest families of flowering plants, is the major contributor to the naturalized flora globally as well as in Taiwan (Pyšek et al., 2004;Wu et al., 2004;Wu and Wang, 2005). Many naturalized Asteraceae plants were reported in Taiwan in recent years (Chang et al., 2002;Chen, 2007;Chung et al., 2007Chung et al., , 2008Hsu et al., 2006;Jung et al., 2005Jung et al., , 2006Jung et al., , 2008Peng, 2004, Tseng et al., 2008;Wang and Chen, 2006;Yang et al., 2001;Yang and Hsieh, 2006). Most of them were introduced casually (Chang et al., 2002;Chen, 2007;Chung et al., 2007Chung et al., , 2008Hsu et al., 2006;Jung et al., 2005Jung et al., , 2006Jung et al., , 2008Wang and Chen, 2006;Yang and Hsieh, 2006). ...
