cucurbitales

Several wood features of this family are more primitive than those of the other families in the order Cucurbitales.

The Cucurbitales are an order of cosmopolitan plants with distribution, particularly diverse in the tropics.

Coriariaceae is now placed in the order Cucurbitales.

It is sister to a clade consisting of Fagales and Cucurbitales.

The Cucurbitales are an order of flowering plants, included in the rosid group of dicotyledons.

The patterns of speciation in the Cucurbitales is diversified in a high number of species.

Volume 10 covers the family Myrtaceae and the orders Cucurbitales and Sapindales.

One of major characteristics of the Cucurbitales is the presence of unisexual flowers, with thick pointed petals (whenever present).

Cucurbitales form an important component of tropical forests from low to montane forests with greater representation in terms of number of species.

The Anisophylleaceae are a small family with four genera, in the order Cucurbitales, according to the APG II.

All these families belong to the orders Cucurbitales, Fagales, and Rosales, which together with the Fabales form a clade of eurosids.

Nickrent et al. (2004) showed Cytineae was related to Malvales and Apodantheae to either Malvales or Cucurbitales.

Mitochondrial and nuclear DNA sequences confidently place the Apodanthaceae in the Cucurbitales, where they also fit well in terms of their flower morphology.

The Cucurbitales comprise the families: Apodanthaceae, Anisophylleaceae, Begoniaceae, Coriariaceae, Corynocarpaceae, Cucurbitaceae, Tetramelaceae, and Datiscaceae.

Before DNA-molecular classifications, the species placed now in Cucurbitales order, were assigned to orders as diverse as Ranunculales, Malpighiales, Violales, and Rafflesiales.

The order Cucurbitales in the eurosid I clade comprises almost 2600 species in 109 or 110 genera in eight families, tropical and temperate, of very different sizes, morphology, and ecology.

According to Engler and Prantl, Sympetalae includes the following orders: Diapensiales, Ericales, Primulales, Plumbaginales, Ebenales, Contortae, Tubiflorae, Plantaginales, Rubiales, Cucurbitales, and Campanulatae.
