Muthu ji I don't feel very confident about the identification of above photograph as P. cineraria, because the spines are clearly longer, stronger and paired, and inflorescence much denser.
Both P. juliflora and P. cineraria grow in Delhi and they are quite distinct. In P. cineraria the spines are much shorter, solitary and randomly scattered, it is a taller tree, the spikes are slender, more yellower in colour and lax. It is also common to see rounded insect galls hanging from the tree. pods are slightly flattened and curved P. juliflora is a medium sized tree or shrub, the spines are longer and paired in leaf axils. The infloresnce is much more dense and pale yellow or creamy in colour, with greenish tinge. the pods are slender, long and cylindrical. I am uploading both species separately. -- Dr. Gurcharan Singh Retired Associate Professor SGTB Khalsa College, University of Delhi, Delhi-110007 Res: 932 Anand Kunj, Vikas Puri, New Delhi-110018.
