The present study reviews the pattern of modern pollen-rain carried out from south-western Madhya Pradesh, India, which
largely revealed that Tectona grandis (teak), despite being an enormous pollen producer (7500 average number of absolute
pollen/flower) (Bhattacharya et al., 1999) and the dominant forest constituent (80 to 95% of the total forest constituents), is
recorded mostly in low frequencies, attributable to its low pollen dispersal efficiency as well as poor pollen preservation in
the sediments. However, Madhuca indica (Mahua) and other dominant members of Sapotaceae (cf. Manilkara hexandra and
Mimusops elangi) have always shown theirs? typical behaviour in the pollen spectra and representing in high frequencies, which
is assigned to its local abundance around the provenance of the samples, coupled with high dispersal efficiency as well as good
pollen preservation in the sediments. Meanwhile, the other usual and characteristic associates of teak (Tectona grandis) in the
tropical deciduous forests, despite being the common elements of the forests, are under-represented, sporadically represented
or not represented at all, which could be ascribed to theirs? low pollen productivity owing to entomogamy. Various factors that
affect the deposition pattern of the diverse constituents of the tropical deciduous forests dominated by teak (Tectona grandis)
have been discussed and suggestions were also given while interpreting the pollen sequences generated from the sedimentary
beds in terms of past vegetation and climate in a chronological order in the region during the Late Quaternary Period.

Birbal Sahni Research Scholar (BSRS) at Birbal Sahni Institute of Palaeobotany (BSIP), Lucknow (U.P., India) and postdoctoral studies/Birbal Sahni Research
Associateship from the same institute (BSIP). He has recently joined the institute (BSIP) as Scientist ?B? and carrying out research on palaeoclimatology with the
use of pollen as proxy during the Late Quaternary Period. He has published 18 papers in reputed journals, reviewed papers for the international peer reviewed
journal and presented work in international conferences (WCPS, Thailand, IPC/IOPC, Japan, PAGES, Goa).
