Shrub for ID : 240511 : AK-3: Taken at Muscat, Oman on the 3rd of Sept, 2010. Small shrubs. Some Cassia?

Senna italica Mill. subsp. italica syn C. italica (Mill.) Spreng. syn C. obtusa Roxb. of Caesalpiniaceae. This plant also occurs in monsoon in dry areas of peninsular India. In Maharashtra it is known as Bhui-Tarwad.


Yes i agree with .. its Senna italica Mill. [syn. Cassia italica (Mill.) Spreng.]
but I don’t think so there is need to write subsp. italica unless someone is writing some other subsp. under the same species..
