Dear Friends,

Came across this tree at Matheran (Sunset pt.) (14-11-2009).

Flowers were Fragrant. Is this Canthium Sp. (Rubiaceae family)??

Thanks & best wishes
Prashant

You can note that stamens are 8 and the filaments are flattened and
almost fused together which leads to Rutaceae. Rubiaceae would have
stamens as many as the corolla lobes and attached to the lobes. This
is Atalantia racemosa or Makadlimbu in Marathi. The citrous smell of
leaves could also have given the clue on ID. Regards
Shrikant

To me it appears like some citron.

It is clearly a member of Rutaceae and not Rubiaceae (where stamen number equals petals and filaments are not dilated). Citrus has stamens 4+ times the number of petals, whereas Atlantia has twice the number of petals. Here we can count 4 petals and 8 stamens in several flowers. Obviously Pravin ji and Shrikant ji are justified in identifying it as Atalantia  racemosa.

Dear Pravin ji, Shrikant ji and Prashant ji

 

Whereas we are sure the plant belongs to genus Atalantia, please make sure it is A. racemosa. Another species A. malabarica (Rafin.) Tanaka (syn: A. monophylla Correa) also grows in the same general area. It has longer pedicels (8-12 mm), 4 petals, 8 stamens, fls in corymbs. A. racemosa has shorter pedicels, fls in up to 8 cm long racemes, 3-4 calyx lobes. To me pedicels look longer, and inflorescence more of a corymb, besides 4 petals and 8 stamens. Won't it be better identified as A. malabarica?. I have no field experience of this genus and am commenting solely based on literature information.

 

PS: I don't know wherefrom this noreply mail crept into the thread.

Reply from Singh ji in another thread:

"Shrikantji
I find the filaments are connate in photograph. They are free in A. racemosa. Could it be A. monophylla (syn or syn of A. malabarica).
