“…The phylogeny of Kadereit et al (1994Kadereit et al ( , 1995, based on 39 morphological characters, resulted in Papaveraceae s. s. as sister to a clade consisting of Hypecoum and Fumariaceae. The position of Pteridophyllum was not tested, since the tree was rooted with this genus, apparently based mainly on the absence of two characters found in all other papaveraceous taxa: laticifers/idioblasts (Ernst 1962;Lidén 1986Lidén , 1993aLidén , 1993b and calcium oxalate crystals in the seed's inner epidermis of the outer integument (Brü ckner 1985). Hoot et al (1997) tested the rooting of Papaveraceae s. l. using chloroplast genes atpB and rbcL for 15 genera and four outgroup taxa (Illicium L., Asarum, Platanus L. and Euptelea).…”

“…Morphological characteristics of Pteridophylloideae, Hypecoideae, Fumarioideae, and Papaveroideae are summarized in Table 1. Pteridophylloideae, consisting of the monotypic genus Pteridophyllum from the forests of Honshu, Japan, differ from all other papaveraceous subfamilies in the absence of secretory idioblasts or laticifers (Ernst 1962;Lidén 1986Lidén , 1993aLidén , 1993b) and lack of calcium oxalate crystals in the inner epider-mis of the outer integument (Brü ckner 1985). Hypecoideae (one genus, 18 species; Lidén 1993a) are herbs from the Mediterranean to central Asia.…”

To explore the taxonomic status, phylogenetic patterns, and character evolution of various groups within Papaveraceae s. l. (Pteridophylloideae, Papaveroideae, Hypecoideae, and Fumarioideae), two data sets were created and analyzed using Bayesian inference, maximum likelihood, and parsimony methods: 1) a Ranunculales data set for 82 genera representing all of the major families within the order using three chloroplast DNA regions (atpB, rbcL, and matK) and nuclear 26S ribosomal DNA, and 2) a Papaveraceae s. l. data set for an expanded sampling of the family (27 genera, 40 species) consisting of chloroplast sequences only. Branch support values on the resulting trees derived from the combined data for both the Ranunculales and Papaveraceae s. l. data sets were comparable among the various ranunculalean families and supported subfamilial recognition of Pteridophylloideae, Papaveroideae, Hypecoideae, and Fumarioideae. Within Papaveraceae s. l., most analyses of both data sets resolved the position of Pteridophyllum as sister to all remaining subfamilies and Hypecoum as sister to Fumarioideae; branch support for these relationships varied from excellent to weak. Within Papaveroideae and Fumarioideae, most taxonomic groups previously proposed were recovered, including a well-supported clade of South African species. Optimization of sixteen key morphological characters on the Bayesian inference tree indicated that some characters (e.g. presence of laticifers and nectaries, floral symmetry, spurred petals, and type of androecium) are highly congruent with the molecular phylogeny. Intrafamilial phylogenetic relationships and character evolution of the various taxa within Papaveraceae s. l. are further discussed.

A study of the floral development of Dicentra formosa, Corydalis lutea, and Hypecoum procumbens was carried out to better understand the nature of the androecium in Fumariaceae. Sepals emerge successively in a median position and are followed by two alternating pairs of petals. Four stamen primordia are formed in a diagonal position. They are promptly followed by two lateral, slightly externally inserted primordia. In Dicentra and Corydalis the stamens arise on two crescent-shaped protuberances. In Hypecoum, four diagonal androecial primordia fuse into two median staminal complexes. The gynoecium emerges as a girdling primordium with four growth centers. Different interpretations of the androecium are discussed. It is demonstrated that the androecium in the Fumariaceae consists basically of two whorls: an outer whorl of four alternipetalous stamens and an inner whorl of two lateral stamens superposed to the outer petals. The monothecal nature of the alternipetalous stamens and the fusion of the stamens in two triplets is probably caused by a spatial median compression of the flower bud. The androecium of Hypecoum is the result of interprimordial growth between the pairs of monothecal stamens, and the androecium of Pteridophyllum arises through the loss of the two lateral stamens superposed to the outer petals. Key words: Fumariaceae, floral development, androecium, stamen whorls.
