Looks like Senna siamia, but then it flowers in Delhi only in November-December


Thank you for the probable ID of this tree, the keys you compiled to identify Cassia complex is excellent for an average user like me. A website informs, “…The flowering period is long, and flowers may often be found at various seasons (Troup 1921)….” for Senna siameahttp://www.winrock.org/fnrm/factnet/factpub/FACTSH/S_siamea.html


For the past few months whatever i have learnt about plants is from you, and …

Request for ID GD28112012:  a friend of mine (and me too) is pretty curious about exactly what this tree is. We, as laymen, call it subabool (as we call many other similar trees). These are planted roadside in Nagpur and are very common. Please reply.


most of the babool are some species of Acacia OR Leucaena … this is not subabool. It is some species of Cassia.


Yes it is Cassia. Any possibilities for this to be C.siamea ?

Most probably it is Senna siamea (= Cassia siamea) just as … hinted … family Fabaceae.
Commonly known as: Siamese cassia, Siamese senna, Thai cassia, Thailand shower … no vernacular names
Native of Indo-China, Malaysia; naturalized / cultivated throughout tropics.


Yes, seems like that. Thanks all.
