Dear Members,
Am posting some photos of Box Elder (Acer negundo ) an introduced  monoecious  plant
species from Srinagar.  The male plant has long attractive flowers which hang in panicles and appear just before the leaves in March .It seems that photos of male flowering plants from this locality have not been posted before here. Previous posts by Gurcharan Ji and Aarti Ji are of leaves which appear just after flowers.  It is also called Ash Maple because the leaves are pinnately compound as in Ash.
Habitat:  Corner of a field in Srinagar
Habit: Tree 15-20 feet high
Inflorescence: Flowers hanging in panicles at the end of long hairy pedicels 3-4cm or more in length.
Petals: Absent
Perianth: minute

Regards
Taffazull

Yes Taffazul ji, I had clicked it in July, 2011  when it was fruiting in Hazuribagh garden, where we spent our childhood.

Photo of pinnately compound leaf. Most maples have palmate leaves. This is the only Acer species which can have more than three leaflets.

One more photo'
A photo of a leaf with 6 leaflets. (Photo CC license Attribution only)
A.negundo  is the only Acer species to regularly display more than 3 leaflets (Wikipedia article).
Another interesting fact is that its seeds contain Hypoglycin A which causes Seasonal Equine Myopathy in Horses in some areas of N.America and Europe. 
A closely related toxin in lychee fruit causes encephalopathy in undernourished children who consume the fruit in large amounts  in  lychee growing areas of India in the lychee harvesting season.
