Shing (1999: 350) .</p><p>Type:— CHINA, Guizhou, Wang-mo Xian, Sang-lang District, Du-yi County, 23 December 1991, P.S. Wang 222 (B) (PE [00789734]!).</p><p>= Cyclosorus cuneatus Ching ex K.H. Shing (1999: 347), nom. illeg.</p><p>Distribution:— China and Vietnam.</p><p>Note: Cyclosorus cuneatus Ching ex K.H. Shing is an illegitimate name due to the earlier publication of Cyclosorus cuneatus (C. Christensen 1913: 253) Ching (1941: 243) (baisonym: ≡ Dryopteris cuneata C.Chr.). Currently, Cyclosorus cuneatus (C.Chr.) Ching is a well-placed synonym of Goniopteris cuneata (C.Chr.) Brade (1972: 215) (Fawcett &amp; Smith 2021). The type specimen of Cyclosorus cuneatus Ching ex K.H. Shing was labeled by Ren-Chang Ching as Cyclosorus cuneatus Ching ined. (30 Sep. 1957), which seems like an informal labeling. Without being aware of existing nomenclature, Shing utilized the Ching’s ditto labeled name and also dedicated it to him, which resulted in the publication of an illegitimate name in the Ching’s authority (Shing 1999). Afterward, the name was also utilized in the Flora of China and other literature, probably believing in Ching as authority and not being aware of the Shing’s illegitimate nomenclature (Lin et al. 2013, Li et al. 2013). In the same publication, Shing also described another species, Cyclosorus clavatus K.H. Shing which was later synonymized into Cyclosorus cuneatus Ching ex K.H. Shing in the Flora of China (Lin et al. 2013). This taxon was found closely related to Christella calvescens (Ching 1938: 225) Holttum (1976: 328) in general morphology, venation, and gland structure, but differs in having a sparsely glandular lamina and a long-creeping rhizome (Li et al. 2013). Since the name Cyclosorus clavatus K.H. Shing is available, and has been utilized here to make a new combination (Turland et al. 2018).</p></div>	https://treatment.plazi.org/id/039087E6FFFEE31E8DA7C38875A7F990	Public Domain	No known copyright restrictions apply.

Lindsay was described in Lindsay et al. (2008: 47) as closely related to Christella zeylanica (Fée 1865: 42) Holttum (1974: 208), but differing in the position and arrangement of sori and the structure of indusia. Among the existing generic concepts in the family, the authors adopted the recent classification by Smith et al. (2006), modified from Smith (1990) for the description of the species in the genus Cyclosorus . Lindsay et al. (2008) also overlooked another similar species, Christella semisagittata (Roxburgh 1844: 491) Holttum (1976: 334), which has been kept as a separate species from Christella zeylanica (Fée) Holttum (Holtum 1976, Fawcett &amp; Smith 2021) is often considered the same species by Jenkins et al. (2017). Christella thailandica (S.Linds.) R.Ojha can be distinguished from Christella semisagittata (Roxb.) Holttum by more deeply lobed pinnules (c.&gt; 2 mm), the second pair of veins reaching up to sinus, and closely placed confluent sori (vs. shallowly lobed pinnules up to 1 mm, only the first pair of veins reaching up to sinus, and medial sori) (Roxburgh 1844, Holttum 1976). All the species used by Lindsay et al. (2008) for the comparison have wellaccepted combinations in Christella, so here a new combination is proposed for this taxon.</p></div>	https://treatment.plazi.org/id/039087E6FFFEE31F8DA7C6D8746FFE7D	Public Domain	No known copyright restrictions apply.
