digital photography which allows you to take as many photographs as
possible without much recurring expenditure; it will be useful if one or
two members have a small laptop to download pictures from camera into
storage drives for other members also). I wish I was a part of it, my long
standing desire. Unfortunately I won't be a part of this dedicated team of
explorers, as I am flying to USA towards the end of this month.

to get identifiable photographs. It was a practice (and still with many
often citing time constraint) to take a single (or a few) close up of the
flower only that makes identification a difficult task most of the times.
More so digital photography often gives very confusing estimate of size,
unless a measurable object or scale is used. The size of plant, size and
shape of leaves, their insertion, arrangement of flowers on the
inflorescence axis, bracts (presence, size and shape), pedicel (presence or
absence and length if present), size of calyx in relation to corolla
(including size relation of lobes and tube), corolla colour, length,
diameter; number of sepals, number of petals, size relation of corolla tube
and lobes, numbers of stamens and length, numbers of styles and stigmas and
their length in relation to ovary, the type, shape and size of fruit are
all important characters very crucial in identification. More so in
different families different characters hold more importance, which even
not the trained taxonomists may know for all the families.

photography. Forget about these terms if you are not a botanist.  Just take
a few good photographs of each plant that you encounter, upload it when you
come back, and let the experts extract the identifying features from your
photographs. I hope it would be ideal if you bring back at least four good
photographs of a plant:
