Thanks for the nice pictures Mani ji.  In your second pictures the characteristic oblique leaves are clearly seen.  Oblique meaning shorter at one  h. point at the base of the leaf. Leaves are used in the treatment of colds. Nuts made into rosaries and necklaces  for children to promote good health.!

 

regards,

Rashida.

I'm adding my pics of Putranjiva roxburgii taken at a park which will probably be destroyed as a Metro station is to come up on its site.

Last week I was disappointed to see it closed to the public.

 

Thiru-Vi-Ka park at Shenoynagar, Chennai.

Satish ji,  I think the flowers as seen in the first and last pictures are male. There is a distinction in the pedicels length  and pattern and number of flowers of male and female. The male are yellowish, shortly pedicellate crowded, in rounded axillary clusters on the main or on short axillary branches.  Female flowers are solitary or 2 to 3  together , greenish, in an axil, pedicels 8 -10 mm long.

Drupes: 1-2 cm long, ellipsoid, rounded or pointed at the apex narrowed at the base, white-tomentose, with pedicles 1- 2.5 cm long; stone pointed, rugose, very hard. Ref: Dr. Almeida's flora Vol IV-B.

Rashida.

Thanks for your kind words, Rashida-ji.

I must mention that I have been observing 6 trees of Putranjiva roxburgii in different areas of Chennai and have seen the "olives" only on one tree in another park (May Day park) which has been closed to the public, prior to construction of a Metro station.

I have not been able to see the flowers at all though obviously that one tree has borne flowers.

Is our climate here not conducive to flowering, I wonder. However the trees look healthy enough.

 Regards,

Padmini Raghavan.
