Abstract

Lectotypification for Stellaria depressa Em. Schmid, S. yunnanensis Franch., S. ebracteata Kom., S. filicaulis Makino, and S. pusilla Em. Schmid are designated here.

Keywords

Caryophyllaceae, lectotype, Stellaria

Introduction

The genus Stellaria L. was described by Linnaeus and comprises c. 190 species around the world (Chen and Rabeler 2001; Xu and Ma 2018; Wang et al. 2020; Xu et al. 2020). In China, 69 species were reported, with five new species described recently, of which 33 were endemic (Wu and Ke 1996; Chen and Rabeler 2001; Gan and Li 2014; Xu and Ma 2018; Song et al. 2020; Wang et al. 2020; Yang et al. 2020). During the study on the genus Stellaria in China, we found S. depressa Em. Schmid, S. yunnanensis Franch., S. ebracteata Kom., S. filicaulis Makino and S. pusilla Em. Schmid needed to be lectotypified according to Art. 9.3 and Art. 9.11 of the Shenzhen code (Turland et al. 2018). Hence, these species are lectotypified here after literature survey and specimen examination.

Materials and methods

Specimens of Stellaria depressa, S. yunnanensis, S. ebracteata, S. filicaulis and S. pusilla matching the criteria of original material were searched at K, LE, MAK, P, TNS and Z. The lectotype designations in this paper follow the rules of the Shenzhen Code (Turland et al. 2018). All specimens were examined and studied by authors.

Typification

Stellaria depressa Em. Schmid, Repert. Spec. Nov. Regni Veg. 31: 41 (1932)

Lectotype

(designated here):–China, Tschu-sang-po, am Lanak-La, August 13, 1927, Bosshard s.n. (Z000002693 digital image!, Figure 1; Isolectotypes: China, Aksai-Chin, Bosshard s.n., Z barcode Z000002691 digital image!, China, Ladakh, Zingrul, Bosshard s.n., Z barcode Z000002692 digital image!).

Figure 1. 

Lectotype of S. depressa Em. Schmid (Walter Bosshard, Bosshard s.n., Z000002693).

Note

When Schmid first described S. depressa, he cited three specimens “Bosshard s.n., 16. VII. 1927; Bosshard s.n., 13. VIII. 1927; Bosshard s.n., 5. IX. 1927” collected by Bosshard from Ladakh and Tibet, but he didn’t designate any one of them as holotype in the protologue. According to Stafleu and Cowan (1993), Bosshard’s specimens were deposited in W and Z. We traced three specimens of S. depressa collected by Bosshard deposited in Z (Z000002693 digital image!, Z000002691 digital image!, Z000002692 digital image!). Although they were collected by Bossard at different time, it seems that they were treated as types since they all have the label “Typus”. However, according to Arts. 9.1, 9.6, and 40 Note 1 of the ICN (Turland et al. 2018), none of them can be treated as holotype, but all should be considered as syntypes. Given a label on the specimen sheet with the description matching the protologue of S. depressa, its good preservation, and the perfect presence of flower and inflorescence, Z000002693 is designated here as the lectotype according to Art. 9.3 and 9.4 of the ICN (Turland et al. 2018).

Stellaria yunnanensis Franch., Bull. Soc. Bot. France. 33: 433 (1886)

Lectotype

(designated here):–China, Yunnan, Les collines incultes au dessus de Ta pin tze, September 1, 1882, Delavay 4 (P01902917 digital image!, Figure 2; Isolectotypes: China, Les collines incultes au dessus de Ta pin tze, Delavay 4, P barcodes P01902916 and P01902918–P01902919 digital images!, China, Les pâturages au pied du Tsang chan, au dessus de Ta-li, Delavay 1, P barcodes P01902913–P01902915 digital images!, China, Da-pin-tze, Delavay s.n., K barcode K000723671 digital image!).

Figure 2. 

Lectotype of S. yunnanensis Franch. (J.M. Delavay, Delavay 4, P01902917).

Note

Franch described S. yunnanensis based on two specimens “Delav. Caryoph. n. 1, 4. jul. 1882; Delav. Caryoph. n. 4, 1. sept. 1882” collected by Delavay from Yunnan, China, without designating any one of them as holotype in the protologue. According to Stafleu and Cowan (1976), Delavay’s specimens were deposited in K, P and PC. Eight original materials were found in P (P01902913–P01902919 digital images!) and K (K000723671 digital image!), which all have Delavay’s annotation and are well preserved. The specimens of P all bear the information “Syntype Stellaria yunnanensis Franch.”. P01902917 well presents inflorescence and lower part of the plant and is in line with the protologue. So P01902917 is designated here as the lectotype according to Art. 9.3 and 9.4 of the ICN (Turland et al. 2018).

Stellaria ebracteata Kom., Trudy Imp. S.-Peterburgsk. Bot. Sada. 18: 441 (1901)

Lectotype

(designated here):–North Korea, Ad trajectum Abuzsa-kogar divortium aquarum inter flumina Tumin et Jalu, June 19, 1897, Komarov s.n. (LE01001957 digital image!, Figure 3; Isolectotype: North Korea, Trajectum Czaur-ien in valle fluvii Cham-muri, Komarov s.n., LE barcode LE01001956 digital image!).

Figure 3. 

Lectotype of S. ebracteata Kom. (V. L. Komarov, Komarov s.n., LE01001957).

Note

Komarov described S. ebracteate and cited several specimens “Komarov s.n., 18–27/VI 1894; Komarov s.n., 24/V 1897; Komarov s.n., 12/VI 1897; Komarov s.n., 19/VI 1897” collected by himself, but never designated any one of them as holotype in the protologue. According to Stafleu and Cowan (1979), Komarov’s type specimens were deposited in LE. Two specimens traced in LE (LE01001957 digital image! and LE01001956 digital image!), match “Komarov s.n., 12/VI 1897, Komarov s.n., 19/VI 1897” in the protologue, and should be considered as syntypes following Arts. 9.6 and 40 Note 1 of the ICN (Turland et al. 2018). Unfortunately, due to the possible loss or destruction of specimens, the specimens “Komarov s.n., 18–27/VI 1894” couldn’t be found. Two specimens traced in LE have Komarov’s script “Stellaria ebracteate Kom.”, the description of collecting location, and the label “SYNTYPUS”. Since LE01001957 is morphologically complete with the well presence of flower, inflorescence, and root, LE01001957 is designated here as the lectotype following Art. 9.3 and 9.4 of the ICN (Turland et al. 2018).

Stellaria filicaulis Makino, Bot. Mag. (Tokyo). 15: 113 (1901)

Lectotype

(designated here):–Japan, Tokyo, Koiwa-mura, June 16, 1895, Watanabe s.n. (TNS62378 digital image!, Figure 4; Isolectotypes: Japan, Musashi Prov., Koiwa-mura, Yoda, Makino s.n., MAK barcode MAK009391 digital images!, Japan, Hitachi Prov., Itako, Suzuki s.n., MAK barcode MAK009392 digital images!, Japan, Musashi Prov., Koiwa-mura, Yoda, Watanabe s.n., MAK barcode MAK010156 digital image!).

Figure 4. 

Lectotype of S. filicaulis Makino (Kano Watanabe, Watanabe s.n., TNS62378).

Note

Makino first described S. filicaulis without designating a specimen as holotype but mentioned four specimens “Watanabe s.n., June 16, 1895; Makino s.n., June 23, 1895; Watanabe s.n., June 16, 1895; Suzuki s.n., May 19, 1901” in the protologue. Yet following Arts. 9.6 and 40 Note 1 of the ICN (Turland et al. 2018), these specimens should be treated as syntypes. According to Stafleu and Cowan (1981 and 1988), the original specimens were traced in GH, TI and MAK, but no specimens could be found in GH and TI mentioned in the protologue. Tropicos (Tropicos 2020) cited “Type-Protologue: K. Watanabe s.n. in TI”, but related specimens were not found in TI. Fortunately, original specimens in TNS (TNS62378 digital image!) and MAK (MAK009391–MAK009392 digital images!, MAK010156 digital image!) were traced, with a description of the collecting location and date agreeing with the protologue. They could be confirmed as original specimens. Moreover, Makino might have described S. filicaulis based on one of these specimens because it has a label containing a message which means a new name. Hence, TNS62378 is designated here as the lectotype for its good preservation, the numerous flowers and fruits, and also greatly agreeing with the protologue according to Art. 9.3 and 9.4 of the ICN (Turland et al. 2018).

Stellaria pusilla EM. Schmid, Repert. Spec. Nov. Regni Veg. 31: 41 (1932)

Lectotype

(designated here):–China, Tibet, Panggong Tso, July 25, 1927, Bosshard s.n. (Z000002688 digital image!, Figure 5; Isolectotype: China, Tibet, Panggong Tso, Bosshard s.n., Z barcode Z000002689 and Z000002690 digital image!).

Figure 5. 

Lectotype of S. pusilla Em. Schmid (Walter Bosshard, Bosshard s.n., Z000002688).

Note

S. pusilla was described by Schmid based on three specimens “Bosshard s.n., 25. VII. 1927; Bosshard s.n., 29. VII. 1927; Bosshard s.n., 13. VIII. 1927” collected by Bosshard from China, but he didn’t designate one of them as holotype in the protologue. Plants of Central Asia (Grubov and Kozhevnikov 2007) cited “Panggon Toso July 25, 1927 (typus)”. Yet following Art. 9.6 and Art. 40 Note 1 of the ICN (Turland et al. 2018), none of them can be treated as holotype, but all should be considered as syntypes. Bosshard selected type specimens that were deposited at W and Z (Stafleu and Cowan 1993). Three original specimens were traced deposited in Z (Z000002688 digital image!, Z000002689 digital image!, and Z000002690 digital image!). All of them agreed with the collection location and date in the protologue and had a label “Typus” and another label “Syntype of Stellaria pusilla EM. Schmid” written by Sallucn at the same time. Given its label “Stellaria pusilla Schmid nov. spes” and its good preservation, the presence of flower and lower part of the plant, Z000002688 is designated here as the lectotype following Art. 9.3 and 9.4 of the ICN (Turland et al. 2018).
