Roseodendron

Miranda assigned to Roseodendron the same 2 species that it includes today.

Roseodendron is a genus of flowering plants in the family Bignoniaceae.

Consequently, Roseodendron was resurrected in its original form.

Group 1 is now the genus Roseodendron.

This result had only weak statistical support, but Roseodendron clearly did not group with the remainder of Tabebuia.

His group 1 corresponds to Roseodendron.

One of these clades consisted of the two species that constitute the genus Roseodendron.

Roseodendron was resolved as sister to a clade consisting of Handroanthus and four other genera.

No species that is now assigned to Roseodendron or to Handroanthus is listed below.

Roseodendron and Handroanthus were resurrected from Tabebuia in 2007.

Tabebuia always has a dichotomously branched inflorescence; never a central rachis as in Roseodendron.

The genus Roseodendron was described in 1965 by Faustino Miranda Gonzalez.

Unlike Roseodendron, the calyx of Tabebuia is always distinctly harder and thicker than the corolla.

He divided Tabebuia into 10 species groups, including all of the species now placed in Roseodendron and Handroanthus.

Roseodendron chryseum was named by Sidney Fay Blake in 1918 as a species of Tabebuia.

It consists of two species, Roseodendron donnell-smithii and Roseodendron chryseum.

The authors recommended that Roseodendron be resurrected from Tabebuia, under which most authors of that time had synonymized it.

Some species of Tabebuia have ribbed fruit, but not as conspicuously so as the two species of Roseodendron.

The calyx texture and inflorescence structure of Roseodendron distinguish it clearly from Handroanthus and Tabebuia.

Jacaranda, Campsis, Pyrostegia, Tabebuia, Roseodendron, Handroanthus and Crescentia all have species of horticultural significance, at least in warm climates.

These consist of the 67 species and one hybrid that remain in Tabebuia, the two species transferred to Roseodendron, and the 30 species that are now placed in Handroanthus.

Primavera (Roseodendron donnell-smithii) and a related species with no unique common name (Roseodendron chryseum) were transferred to Roseodendron.

In 2007, a phylogenetic analysis of DNA sequences resolved Roseodendron as one member of a tetratomy that is sister to Sparattosperma, the most basal clade in the Tabebuia alliance.

In 1992, Gentry published a revision of Tabebuia in Flora Neotropica, in which he described 99 species and 1 hybrid, including those species placed by some authors in Roseodendron or Handroanthus.

The genus Roseodendron was established by Faustino Miranda González in 1965 for the two species now known as Roseodendron donnell-smithii and Roseodendron chryseum.
