First of all I appreciate the concept of 'Family of the month' and
thank those who have taken efforts to compile. Many families have
already appeared. I do not know the sequence and the number of
families that are going to appear. I wish to make 'better late than
never' suggestions and request not to take these as interruption in
the current sincere efforts of the members. Pls excuse my ignorance if
whatever I am suggesting is already done.
After years of field work I am able to place plants (by observing and
remembering obvious similarities between them) into just a few
families. The dichotomous keys for families are available in floras
but they can not be recollected and applied to so many families in the
field. If a simple key based on field characters (not on dissected
parts) is made which may lead to a single or a few families, that can
be very useful for a non-botanist like me in placing a plant in a
(single or a few) family for easy ID of species. We can begin by
making a short list of leading families based on the number of species
occuring in India. The list can be of 24 to 36 families to last for
2-3 years' period. The brief features of these select leading families
can be tabulated and posted with each family. The sequence of families
can be as per the current system of classification. For every family,
before posting the plants an introduction to the family may be posted
so that members can look for those features appearing in plants being
posted. This can help to eradicate the apprehension about taxonomy and
will make the event interesting.
For example (Pls ignore the incorrectness if any) the following
information (highlighted in the table) so that the current family can
be compared with other families.
COMMON NAME Spurge
LEADING GENERA Euphorbia, Phyllanthus, Croton, Acalypha, Jatropha
COMPOSITION 300 genera, 5,000 species of herbs, shrubs and trees in
the world and .. genera, ..species in India
CLASSIFICATION Seeds containing 2 cotyledons, perianth 1-2 seriate in
unisexual flowers and absent in bisexual flowers, ovary superior, more
than 1 celled, inflorescence of a cyathium.
DIGNOSTIC FEATURES Leaves usually alternate, stipulate; plants with
milky latex; flowers usually unisexual on same or different plants,
I have been trying to update myself (thogh not yet familiar) on 'How
to ID a family' for a long time which I think is an intrinsic feature
of field botany. I am sure we have experts to generate better ideas on
this subject. Regards, Shrikant
