Roseodendron is a genus of flowering plants in the family Bignoniaceae.[1] It consists of two species, Roseodendron donnell-smithii and Roseodendron chryseum. The type species for the genus is R. donnell-smithii.[2] Both species are cultivated as ornamentals for their numerous, large, yellow flowers.[3]

Roseodendron donnell-smithii is known colloquially as primavera. It is the larger and more frequently planted of the two species.[4] Its wood is sometimes used to make furniture.[1]
It is native to Central America and southern Mexico, but is grown thruout the tropics.[4]

Both species have been placed in Cybistax[3] and in Tabebuia,[5] and they were thought to be closely related to Handroanthus. In 2007, a molecular phylogenetic study showed that Roseodendron is not closer to Tabebuia than Ekmanianthe, not closer to Cybistax than are Godmania and Zeyheria, and not closer to Handroanthus than are Spirotecoma, Parmentiera, Crescentia, and Amphitecna.[6] The authors recommended that Roseodendron be resurrected from Tabebuia, under which most authors of that time had synonymized it.[7]

Were intrigued by this Tabebuia. At first we thought it is T. aurea – but the trunk is not at all deeply fissured.

Sir CV Raman’s ashes are buried at the foot of this tree.

Would appreciate ID!

It is an extremely tall tree – forgot to mention this.

Is this tree Tabebuia donnell-smithii?

A tree expert during the Tree Festival, Neralu [meaning shade in Kannada]- Cubbon Park, Bangalore, said this is Tabebuia serratifolia – does not look like it tho’: http://en.wikipedia.org/wiki/Tabebuia_serratifolia 09/02/201 Young treee – no flowers at the time 

This is indeed Tabebuia donell-smithii. This is marked as one of the heritage trees of Bangalore in the book Heritage trees by Vijay Thiruvady in page 135 where this exact tree is given. Apart from here, its mentioned that there is one more tree in Raj Bhavan. These are the only 2 trees of this species in Bangalore. The tree status is marked as endangered.

Thank you, … for this v. interesting information. Appreciate your sharing this 🙂
