Abstract The Sechium P. Br. genus composed of 11 species, which originated from the mountainous regions of Mesoamerica, have been domes- ticated and diversified. These species are clustered in two large groups: the Mexican clade and the Central American clade. Morphological and molecular studies have shown that species of the Mexican clade are formed through interspecific hybridizations and genetic flow, with the exception of S. mexicanum, which is strongly linked to the genus Sicyos. The objective of this review was to analyze the phylogenetics of Sechium based on morphological and molecular studies, which contributed to taxonomic knowledge and utilization, thereby favoring its conservation and improvement. The Central American clade is well supported with molecular data, but not so with morphological data. The species in this clade were geographically isolated and endemic. S. edule and S. tacaco are exploited species in the agricultural and industrial sectors, and both have an extensive genetic and phenotypic diversity that has allowed them to diversify and expand into different ecological niches.

Phylogenetic Relationships in the Order Cucurbitales and a New Classification of the Gourd Family (Cucurbitaceae)
Schaefer & Renner • Phylogenetic relationships in Cucurbitales TAXON 60 (1) • February 2011: 122–138 TAXONOMY Phylogenetic relationships in the order Cucurbitales and a new classification of the gourd family (Cucurbitaceae) Hanno Schaefer1 & Susanne S. Renner2 1 Harvard University, Department of Organismic and Evolutionary Biology, 22 Divinity Avenue, Cambridge, Massachusetts 02138, U.S.A. 2 University of Munich (LMU), Systematic Botany and Mycology, Menzinger Str. 67, 80638 Munich, Germany Author for correspondence: Hanno Schaefer, [email protected] Abstract We analysed phylogenetic relationships in the order Cucurbitales using 14 DNA regions from the three plant genomes: the mitochondrial nad1 b/c intron and matR gene, the nuclear ribosomal 18S, ITS1-5.8S-ITS2, and 28S genes, and the plastid rbcL, matK, ndhF, atpB, trnL, trnL-trnF, rpl20-rps12, trnS-trnG and trnH-psbA genes, spacers, and introns. The dataset includes 664 ingroup species, representating all but two genera and over 25% of the ca. 2600 species in the order. Maximum likelihood analyses yielded mostly congruent topologies for the datasets from the three genomes. Relationships among the eight families of Cucurbitales were: (Apodanthaceae, Anisophylleaceae, (Cucurbitaceae, ((Coriariaceae, Corynocarpaceae), (Tetramelaceae, (Datiscaceae, Begoniaceae))))). Based on these molecular data and morphological data from the literature, we recircumscribe tribes and genera within Cucurbitaceae and present a more natural classification for this family. Our new system comprises 95 genera in 15 tribes, five of them new: Actinostemmateae, Indofevilleeae, Thladiantheae, Momordiceae, and Siraitieae. Formal naming requires 44 new combinations and two new names in Cucurbitaceae.

New Contribution to the Study of Alien Flora in Romania
SÎRBU CULIŢĂ, OPREA ADRIAN, ELIÁŠ PAVOL jun., FERUS PETER J. Plant Develop. 18(2011): 121-134 NEW CONTRIBUTION TO THE STUDY OF ALIEN FLORA IN ROMANIA SÎRBU CULIŢĂ1, OPREA ADRIAN2, ELIÁŠ PAVOL jun.3, FERUS PETER4 Abstract: In this paper, a number of seventeen alien plant species are presented, one of them being now for the first time reported in Romania (Sedum sarmentosum Bunge). Some species are mentioned for the first time in the flora of Moldavia (Aster novae-angliae L., Cenchrus incertus M. A. Curtis, Chenopodium pumilio R. Br., Fraxinus americana L., Lindernia dubia (L.) Pennell, Petunia × atkinsiana D. Don, Solidago gigantea Aiton, Tagetes erecta L.) or Transylvania (Kochia sieversiana (Pallas) C. A. Mey.), and some are reported from new localities (seven species). For each species, there are presented general data on the geographical origin, its distribution in Europe and worldwide, as well as its invasion history and current distribution in Romania. Some of these species manifest a remarkable spreading tendency, expanding their invasion area in Romania. Voucher specimens were deposited in the Herbarium of University of Agricultural Sciences and Veterinary Medicine Iaşi (IASI). Keywords: alien plants, flora, new records, Romania Introduction According to ANASTASIU & NEGREAN (2005), the alien flora of Romania includes 435 species, of which 88.3% are neophytes and 11.7% are archaeophytes. Therefore, species of alien origin currently represent ca 13% of the total flora of the country, which was estimated by CIOCÂRLAN (2009) to 3335 species. In the last years there is a continuous enrichment of Romania’s flora with new alien plant species [ANASTASIU & NEGREAN, 2008; OPREA & SÎRBU, 2010; SÎRBU & OPREA, 2011].

Quantification of seed shape is a useful tool in plant description for phenotypic characterization and taxonomic analysis. J index gives the percent of similarity of the image of a seed with a geometric figure and it is useful in taxonomy for the study of relationships between plant groups. Geometric figures used as models in the Cucurbitales are the ovoid, two ellipses with different x/y ratios and the outline of the Fibonacci spiral. The images of seeds have been compared with these figures and values of J index obtained. The results obtained for 29 species in the family Cucurbitaceae support a relationship between seed shape and species ecology. Simple seed shape, with images resembling simple geometric figures like the ovoid, ellipse or the Fibonacci spiral, may be a feature in the basal clades of taxonomic groups.

Austrobryonia (Cucurbitaceae), a New Australian Endemic Genus, Is the Closest Living Relative to the Eurasian and Mediterranean Bryonia and Ecballium
Systematic Botany (2008), 33(1): pp. 125–132 © Copyright 2008 by the American Society of Plant Taxonomists Austrobryonia (Cucurbitaceae), a New Australian Endemic Genus, is the Closest Living Relative to the Eurasian and Mediterranean Bryonia and Ecballium Hanno Schaefer,1,3 Ian R. H. Telford,2 and Susanne S. Renner1 1Systematic Botany, Department of Biology, University of Munich (LMU), Menzinger Str. 67, D-80638 Munich, Germany 2N.C.W. Beadle Herbarium, University of New England, Armidale, NSW 2351, Australia 3Author for correspondence ([email protected]) Communicating Editor: Javier Francisco-Ortega Abstract—The Cucurbitaceae genus Austrobryonia, with four species endemic to Australia, is described, illustrated, and placed in a phylogenetic context based on molecular and morphological data. In the Flora of Australia (Telford 1982), all four species were provisionally included in Mukia, but not formally described. Austrobryonia argillicola, A. centralis, A. micrantha, and A. pilbarensis are adapted to arid central regions of Australia. All species are known from several (7–27) localities, and their distributional ranges are allopatric. A phylogenetic analysis of plastid and nuclear DNA sequences that includes all four species in a family-wide context revealed that Austrobryonia is the closest living relative to a Eurasian and Mediterranean clade consisting of Bryonia L. and Ecballium L. An rbcL molecular clock, calibrated with Cucurbitaceae fossils, dates this rare biogeographic disjunction to minimally 42 my ago (with an error of ca. ± 25%), while the crown group of Austrobryonia may be about 8 my old. Keywords—Australia-Eurasia disjunction, molecular clock, Mukia micrantha. The Australian continent is relatively poor in genera and Mukia sp.

Thladiantha Dubia Bunge
Thladiantha dubia Bunge Common Names: Goldencreeper, red hailstone, Manchu tubergourd, thladianthe douteuse (French), Thladianthe, chi bao (pinyin, China) (1,2,6,8,21). Etymology: The genus name Thladiantha comes from Greek ‘thladias-anthos’, meaning ‘eunuch-flower’ probably referring to Bunge’s first impression that the flowers are not capable of producing fruit. The word dubia, in Latin, means ‘doubtful’ (4,9,17). Botanical synonyms: Gymnopetalum horsfieldii Miq., G. piperifolium Miq. (5). FAMILY: Cucurbitaceae (the Gourd family) Quick Notable Features (1,11,12,17): ¬ Dioecious pubescent vine with alternate leaves, climbing by axillary tendrils ¬ Simple, toothed, cordate leaves, with hooked scabrous hairs ¬ Yellow, campanulate, unisexual flowers with recurved lobes ¬ Oblong red or green fruits with 10 linear grooves Plant Height: The “goldencreeper” grows 2-6m long and up to 2m tall (7,12,15). Subspecies/varieties recognized: none found. Most Likely Confused with: Cucurbita ssp., Cucumis ssp., Dioscorea villosa, and Ipomoea ssp. Habitat Preference: T. dubia grows on disturbed sites, along rivers, and on sandy shores. It is shade intolerant and prefers moist, well-drained soils (1,7). Geographic Distribution in Michigan: The goldencreeper was only recently collected outside of cultivation in Washtenaw county (1). Known Elevational Distribution: T. dubia grows up to 1800m above sea level in China (11). Complete Geographic Distribution: Native to East Asia (1), T. dubia was introduced to North America. In the United States it is found in IL, MA, MI, MN, NH, NY, and WI; in Canada in MB, ON, and QC (1,6,9). The goldencreeper is also found in Austria, China, Croatia, Czech 1 Republic, France, Germany, Hungary, Italy, Japan, Lithuania, Poland, Republic of Korea, Romania, Slovakia, Slovenia, Spain, Sweeden, and Ukraine (8,13).
