sharing snap of the Yellow variety of Royal Poinciana (Delonix regia var. flavida )…commonly called Gulmohar.
Although it is endemic to Madagascar….it is widely grown in India as an avenue tree.
We call it Radha-choora in Bengali….as the red Gulmohar is called Krishna-choora.


This looks more like Caesalpinia pulcherrima var. flava, rather than Delonix. Shots of the entire plant would be helpful. 


Delonix regia var. flavida – efloraofindia | Google Groups

I even thought of Caesalpinia pulcherrima var. flava even before looking at the reply of Kenneth. Delonix is a tall tree, whereas caesalpinia is mostly a shrub or small tree.


Caesalpinia pulcherrima for me too


Okay…thanks for the correct ID of the flower…  but the yellow Delonix and Caesalpinia look very similar….isnt it??


This appears to be Yellow Peacock Flower from Gulmohar family. (pl check Caesalpinia pulcherrima)


Last month you had raised question about differences between Caesalpinia pulcherrima var. flava and Delonix regia var. flavida. Today I had a casual check and found these:
Sepals in Delonix are narrower and valvate in bud, in Caesalpinia they are broader and imbricate
Stamens slightly longer than petals in Delonix, they are 2-3 times longer in Caesalpinia
Fruits 30-50 cm long in Delonix, less than 10 cm in Caesalpinia


Thank you … but I think it may be … who raised the doubt because it was surely not me.


I think it was


My layman’s understanding is that Caesalpinia pulcherrima is a bush and can be yellow (Radha chuda) and red (Krishna chuda) whereas delonix regia can be pink bright pink or yellow and it is a tree. Caesalpinia’s identifying characteristic is its very long stamens. 

In Bengal gulmohur is also known as Krishna chuda. 

Any corrections welcome.


Plant posted by … concluded as NOT Delonix regia var. flavida Stehle (syn. of Delonix regia (Hook.) Raf.)
Would like to resolve the ID of all yellow flowered variety OR form of Caesalpinia pulcherrima posted by …
It could be any of the following two:
  1. Caesalpinia pulcherrima var. flava Bailey & Rehder … synonym of Caesalpinia pulcherrima (L.) Sw.
  2. Caesalpinia pulcherrima f. flava (Degener) H. St. John

Resolving this query will help posting in the coming week.


Please post the link/resurface photographs on Monday. Perhaps it will get resolved when all these taxa are uploaded by different members.

Common names for this species include Poinciana, Peacock Flower, Red Bird of Paradise, Mexican Bird of Paradise, Dwarf Poinciana, Pride of Barbados, and flamboyan-de-jardin. It is a shrub growing to 3 m tall, native to tropical America. The leaves are bipinnate, 20-40 cm long, bearing 3-10 pairs of pinnae, each with 6-10 pairs of leaflets 15-25 mm long and 10-15 mm broad. The flowers are borne in racemes up to 20 cm long, each flower with five yellow, orange or red petals. The fruit is a pod 6-12 cm long.

Fwd: Request to help about the nomenclature of Caesalpinia pulcherrima : 7 posts by 4 authors. Attachments (1) – 4 Mb.
I have collected Caesalpinia pulcherrima with three colour variation. I have consulted IPNI, POWO, The Plant List but it was not possible for me to come with any final conclusion. I am sending the picture of plants with two colour variation. May I request you help me to get the exact nomenclature.

In Hindustani, these are known as Krishna Chura n Radha Chura. 


Pl. go through efi site pages at Caesalpinia pulcherrima & Caesalpinia pulcherrima f. flava
At the most, you can talk of them as different forms. 


i did not realize that … this is peacock flower is also known as krishnachura and radha chura. i thought krishnachura is delonix regia… in its red/scarlet// or yellow flower varieties and radhachura is one of the peltophorums … esp copper pod variety.
well, live and learn i guess. or there is a mix up in colloquial names used by mali and vendors.


Third color variant ?? Please show. 

I have heard about a Green variant, not seen yet. 

I don’t have pictures. seen in botanical garden in Miami in the 80s. white and yellow varieties, and red… our krishnacuraie Delonix regia was very common in southern florida nurseries then.  fallen out of favor it seems because hurricanes uproot them…
just like they do it here in southern 24 paraganas in west Bengal….
