May be Albizia lucidior.


… is right.  The characters appear to be within the range of variation of Albizia lucidior having 1-3 pairs of pinnae and (1-) 2-5 (-7) pairs of leaflets, acuminate at apex and the terminal, once or twice branched panicles of heads (2-few-together) and the latter with 10-15 dimorphic flowers (central flower different from the marginal flowers). Image of the pods are welcome.




Seeking Id of a Albizia species: 2 high res. images.
I would like to seek ID for a Albizia sp.


Please check Albizia lebbeck (L.) Benth. !


Thank you for your valuable suggestions on this species. However, I feel this species does not qualify to be called A. lebbeck. Because Alebbeck has leaves rounded at apex and base, seeds 5-15 whereas this Albizia has acute or shortly acuminate apex and cuneate base, and seeds not more than 8 nos per pod. Moreover, Pinnae not more than 3 pairs, and leaflets not more than 7 pairs in this species.


Albizia lucidior (Steud.) I.C.Nielson ex H.Hara ??


Some morphological characteristics of the species are:

Rachis: 7 – 17 cm long
Base gland: rounded or elliptical
Apical gland: 1 or 2 (rounded)
Pinnae: 1 – 3 pairs
Leaflets: 2 – 7 pairs
Leaflet: 4 – 7.5 x 1.6 – 3.5 cm
Petiole: c. 2 mm long
Pod: 9 – 20 x 2 – 3 cm
Seeds: 3 to 8 nos (ca. 5 to 8 mm long).
The Pinnae and leaflets are matching with A. lucidior but other characters are mismatching. Probably, it refers to this species only.
