Habit: spiny climber ; habitat: hill;
flower details: whitish colour; stamen-10. petal-5; flowering: May, sweet high scented 
What hill, ..., Chittagong?
If yes, check Paramignya citrifolia Hook. f.
Hill forest  
I wanted to know if it is in Chittagong, and species distribution -
  1. P. citrifolia Hook. f. - Chittagong
  2. P. griffithii Hook. f. - Silhet
  3. P. monophylla Wight - Sikkim Himalaya and other places in India
Since, filaments are free, and spine short I selected no.1 above.
P. scandens (Griff); Synonyms : Limonia citrifolia Roxb. (1832), Citrus scandens Griff. (1854), P. citrifolia Oliver (1861), P. griffithi Hook (1875)
In Bangladesh P. scandens found in the forest of Sylhet and Chittagong Hill Tracts (Hook,1875)
I understand Sourav, we all have our priorities to be taken care of.
About Paramignya I copied what I found in FBI (attached here). As for current accepted name you may visit -
  1. http://www.ars-grin.gov/cgi-bin/npgs/html/splist.pl?8853
  2. http://www.theplantlist.org/1.1/browse/A/Rutaceae/Paramignya/

Have some pictures in details of this climber plants 
Attached here the full description of P. citirfolia Hook. f.. in FBI.
Bangal Plants refers only one Paramignya - citrifolia
The photographs show 1) some leaves with acute and others abruptly obtusely acuminate apices, 2) filaments longer than anthers 3) filaments free, and one or two flowers with columnar disc?
So. I think we can see features of both citrifolia and griffithii. Perhaps this is the reason behind your latest lit. clubbing them together! In addition, you may like to go through Flora Indica.
