Three species which have been introduced in India are quite confusing, with differences as below as per Lucid Central <https://keyserver.lucidcentral.org/weeds/data/media/Html/acacia_dealbata_subsp._dealbata.htm> :
Silver wattle (*Acacia dealbata* subsp. *dealbata*) may be confused with several other native wattles (*Acacia* spp.) including black wattle (*Acacia mearnsii*), Sydney green wattle (*Acacia decurrens*), green wattle (*Acacia irrorata*), northern silver wattle (*Acacia leucoclada*), Bodalla silver wattle (*Acacia silvestris*), dwarf silver wattle (*Acacia nanodealbata*), Cootamundra wattle (*Acacia baileyana*) and Karri wattle (*Acacia pentadenia*). These species can be distinguished by the following differences: - silver wattle (*Acacia dealbata* subsp. *dealbata* <https://keyserver.lucidcentral.org/weeds/data/media/Html/acacia_dealbata_subsp._dealbata.htm>) has* young branches and foliage tips that are finely hairy and whitish-green or whitish-yellow in colour (i.e. pruinose).* *Its silvery-grey leaves* *have numerous (10-30) pairs of hairy branchlets (i.e. pinnae). *These leaves are shortly stalked (i.e. petiolate) and there is usually a small raised structure (i.e. gland) near the top of this leaf stalk (i.e. petiole). There are also similar glands at the junction of the each of the pairs of branchlets (i.e. jugary glands). *The leaflets are relatively small (1.5-6 mm long) and usually quite elongated in shape. Its flowers are yellow or golden yellow* and borne in small globular clusters, which are arranged into larger elongated compound clusters (i.e. racemes or panicles). The pods are relatively large (20-115 mm long and 6-14 mm wide). - black wattle (*Acacia mearnsii <https://keys.lucidcentral.org/keys/v3/eafrinet/weeds/key/weeds/Media/Html/Acacia_mearnsii_(Black_Wattle).htm>*) has* young branches and foliage tips that are finely hairy and yellow or greenish-yellow in colour (i.e. not pruinose)*. *Its dark green leaves have numerous (7-31) pairs of hairy branchlets (i.e. pinnae). *These leaves are shortly stalked (i.e. petiolate) and there is usually a small raised structure (i.e. gland) near the top of this leaf stalk (i.e. petiole). There are also similar glands at the junction of the each of the pairs of branchlets (i.e. jugary glands), and also between some or all pairs of branchlets (i.e. interjugary glands). *The leaflets are quite small (1-3.5 mm long) and usually not particularly elongated in shape. Its flowers are pale yellow or cream-coloured *and borne in small globular clusters, which are arranged into larger elongated compound clusters (i.e. racemes or panicles). The pods are relatively large (30-150 mm long and 4-8 mm wide). - Sydney green wattle (*Acacia decurrens <https://keyserver.lucidcentral.org/weeds/data/media/Html/acacia_decurrens.htm>*) has *young branches with conspicuous flanges and foliage tips that are mostly hairless and yellowish in colour (i.e. not pruinose). Its dark green leaves have several to numerous (3-13) pairs of hairless branchlets (i.e. pinnae).* These leaves are shortly stalked (i.e. petiolate) and there is usually a small raised structure (i.e. gland) near the top of this leaf stalk (i.e. petiole). There are also similar glands at the junction of the each of the pairs of branchlets (i.e. jugary glands).* The leaflets are quite large (5-15 mm long) and very narrow. Its flowers are yellow or golden yellow *and borne in small globular clusters, which are arranged into larger elongated compound clusters (i.e. racemes or panicles). The pods are relatively large (20-105 mm long and 4-9 mm wide). Going by the above keys and links, I think it may be *Acacia dealbata* subsp. *dealbata* <https://keyserver.lucidcentral.org/weeds/data/media/Html/acacia_dealbata_subsp._dealbata.htm> Hi, Mohina ji, May I request you to pl. post high res. images to verify and check the details.
