“…The presence or absence of micropylar and chalazal (character 087) endosperm haustoria shows an interesting pattern in Asterales (Tobe and Morin 1996). The four-family clade with Menyanthaceae, Goodeniaceae, Calyceraceae, and Asteraceae first identified by cladistic analyses of nucleotide sequence data can be characterized, inter alia, by the absence of both chalazal and micropylar endosperm haustoria, while at least a subclade of Campanulaceae sensu lato is characterized by the presence of both chalazal and micropylar haustoria.…”

“…Embryological data were collected from literature (Rosén 1938;Kapil and Vijayaraghavan 1965;Davis 1966;Brewbaker 1967;Subramanyam 1970;Vijayaraghavan and Malik 1972;Bhatnagar 1973;Gardner 1976;Kamelina 1984;Dahlgren 1991;Johri et al 1992;Kapil and Bhatnagar 1992;Backlund and Donoghue 1996;Pacini 1996;Tobe and Morin 1996;Takhtajan 1997). The definitions of the embryological characters follow Johri et al (1992), unless otherwise stated.…”

“…071 Number of middle layers: 0 p one, 1 p two, 2 p three 072 Tapetum type: 0 p glandular, 1 p amoeboid Most of the Asterales for which this character is known have a glandular tapetum (Tobe and Morin 1996). The exception is Asteraceae, where the tapetum is amoeboid (Davis 1966).…”

“…However, the thickness of the single integument is variable and can be divided into two nonoverlapping states. Thick integuments are found in Menyanthaceae, Goodeniaceae, and Asteraceae (Tobe and Morin 1996;Inoeu and Tobe 1999). In all other ingroup taxa, either the integument is thin or the thickness is unknown.…”

We obtained two most parsimonious cladograms using a data set of 100 characters derived from morphology, anatomy, embryology, chemistry, and karyology, combined with three nucleotide sequence data sets (the chloroplast genes atpB, ndhF, and rbcL) in a phylogenetic analysis of all 12 currently recognized families in the angiosperm order Asterales, represented by 40 genera. Most clades were supported by a jackknife value of at least 50% and a Bremer support of 5 or more. Rousseaceae sensu lato (including Carpodetaceae), together with Pentaphragmataceae and Campanulaceae s.l., is the sister group to the rest of the Asterales. A sister group relationship between Donatia and Stylidiaceae is well supported both morphologically and by molecular data, and we suggest that Donatia should again be treated as a subfamily in Stylidiaceae. The sister group relationship between Calyceraceae and Asteraceae is well supported.

“…Kamel (2005) achieved similar results when investigating the seed protein profiles of the same taxa. These results can favor to some extent the views stating that Lobelia should not be separated from the Campanulaceae in a separate Lobeliaceae (Tobe & Morin, 1996;Thorne, 1992and Cronquist 1981& 1988. Concerning the remaining taxa Legousia speculum-veneris (41), Phyteuma orbiculare (42), Symphyandra armena (46) S. zanzegura (47) and Trachelium coeruleum (48), the following will be reviewed:…”

Systematic implications of seed coat morphology in Campanulaceae Juss.

et al. 2006

I n the present study the seed coat micromorphology of 51 accessions of the Campanulaceae s. l. were investigated via SEM, the selected OTU ' s include accessions representing 11 genera and 35 species of the subfamilies: Campanuloideae and Lobelioideae. This study is an attempt to investigate variation between the species and the taxonomic relationships between them. Variations in seed coat micro-sculpture supported the monophyly of the family, favored the retention of Lobelia in the Campanulaceae, showed a relatively isolated nature of Edraianthus serbicus and suggested that the genus Campanula as is currently constituted may be polyphyletic and needs further studies. The study also recorded a relatively high degree of polymorphism within the seed shape and seed coats of the different accessions of the same species, thus suggesting more future studies for their re-evaluation.
