“…Our fi ndings are in agreement with the previous results on the other species of the genus (Babcock 1947a, b, Metcalfe and Chalk 1979, Enke and Gemeinholzer 2008, Enke 2009, Enke et al 2011, 2015, Yildirim et al 2011. The additional morphological, anatomical and cytogenetical characters supporting systematic delimitation of the genus have been used because the molecular analyses by Enke (2009) could not support the current taxonomic sections (Babcock 1947b). Enke (2008) pointed that the surface features of achene, pappus and style are taxonomically valuable, mainly at species level in Crepis.…”

“…4, and its genome size (1C-value) is 6.48 pg. The genome size (1C-value) in C. turcica is 6.41 pg (Enke 2009), and thus there is slight difference in genome size between C. macropus and C. turcica. According to Leitch et al (1998) and Soltis et al (2003), genome sizes can be assigned to a series of distinct categories: very small (1C ≤ 1.4 pg), small (1.4 < 1C ≤ 3.5 pg), intermediate 3.5 < 1C < 14 pg), large (14 ≤ 1C < 35 pg) and very large (1C ≥ 35 pg).…”

“…As studies in the Cichorieae have shown before (Pak and Kawano 1990, Pak 1993, Pak et al 2001, Zhu et al 2006, Sennikov and Illarionova 2008, achene anatomy is helpful in the generic delimitation and infrageneric classifi cation of Crepis (Enke 2008, 2009, Jana and Mukherjee 2012. In general the achene surface features are also taxonomically valuable, mainly at species level, and more rarely concur with supraspecifi c delimitation (Kilian et al 2008).…”

“…The style morphology has been an important morphological character in major clade delimitation of the Asteraceae (Bremer 1996). Some taxonomic value of micromorphology of the pappus and style has been reported in Crepis (Enke 2008(Enke , 2009). Stem and leaf anatomy are considered as diacritical character in some groups of the tribe Cichorieae (Carlquist 1967), but there are rare data on stem and leaf anatomy of Crepis in the literature (Metcalfe and Chalk 1979).…”

“…Most of the micromorphological, anatomical and cytogenetical studies conducted in Crepis have concentrated on common species, with some work having been interested in endemic species (Kamari et al 1991, Kamari 1992, Enke 2009, Enke et al 2011, Siljak-Yakovlev and Peruzzi 2012. To our knowledge, except the chromosome counting of C. dioritica (2n = 8, Davis et al 1988) in Turkey, no micromorphological, anatomical and cytogenetic studies have been reported for Turkish endemic species of Crepis.…”

-In the present study, the micromorphological structure of achene, pappus and style using scanning electron microscope (SEM), stomatal characteristics, anatomy of stem and achene together with chromosome number and nuclear DNA content of the Turkish endemic Crepis macropus Boiss. & Heldr. are provided in order to expand knowledge of its taxonomy. The SEM studies in this species show that dense spiny cells are found on the achene surface, the pappus bristle has 3-5 spikes and the style possesses slender papillae. The stem structure is composed of epidermis, collenchyma, parenchymatous cortex and pith. The species has anomocytic stomata in both the upper and the lower surface of the leaves. The pericarp of the achene is mainly composed of several layers of sclerenchymatous cells. In this species, the chromosome number is 2n = 2x = 8, karyotype consists of two submetacentric and six subtelocentric chromosomes and nuclear DNA content (2C-value) is 12.96 pg. These data are presented here for the fi rst time and their taxonomic values are discussed.

The current study deals with the detailed morphology investigation of eight Cypsela species belonging to tribe Cichoreae. The different Cypsela types were described, explained, compared, and their taxonomic significance is discussed in detail. Light microscopy (LM) and scanning electron microscopy (SEM) have been used to highlight quantitative and qualitative characters of underestudied species. Cypsela exhibit great diversity in macro and micromorphological features such as shape, color, length, width, anticlinal and periclinal wall patterns, surface patterns, epicuticular projections. Majority of Cypsela species were brownish in color and their size ranges from 2.16 to 3.98 mm in length and 1.16 to 0.82 mm in breadth. A great diversity in Cypsela shapes like oblanceolate to obovate, obovoid to cylindrical, obvate, narrowly lanceolate were observed. Most of the platelets having epicuticular projections were observed. The surface pattern on the cypsela surface varied from rugose papillate, verrucose papillate, and striated. On the basis of considerable variations observed, the present study can assist as useful constraints at various taxonomic levels. The aim of the present study is to provide a comprehensive description of the Cypsela morphology and to determine the extent to which these micro morphological data can be used as a taxonomic character to delineate various taxa belonging to the tribe Cichoreae.

Typification of the Linnaean name Crepis vesicaria (Compositae: Cichorieae) revisited

The typification of the Linnaean name Crepis vesicaria (Compositae: Cichorieae) is revised. This name had previously been “lectotypified” by Babcock in 1947 on a specimen kept in LINN (Herb. Linnaeus No. 955.3). However, Linnaeus cited in the protologue a specimen from the Joachim Burser Herbarium, currently preserved at UPS‐BURSER (Herb. Burser VI: 70). According to the International Code of Nomenclature for algae, fungi, and plants (Art. 9.12 of the Shenzhen Code of 2018), this is a syntype which must be chosen as the lectotype.
