 Welcome
to my Systematics of Agathis
Salisb. website.
This is being steadily assembled from
bits and pieces produced during the
course of my doctoral study of the genus
at the University of Oxford, supervised
by Stephen A. Harris in
Oxford and by Aljos Farjon at the Royal
Botanic Gardens, Kew.
Agathis
is a genus of tropical conifers which
belongs to the Araucariaceae,
the same family as the monkey-puzzles and
Cook-pines (Araucaria) and the
Wollemi Pine (Wollemia). Agathis
trees are usually huge trees of lowland
rain forests, though some grow in mossy
forests on mountain tops, and another (as
above) grows as low candelabra-like forms
in low scrubland. The genus is
distributed from Malaysia, Brunei and
Indonesia, through New Guinea, Queensland
and the eastern Solomons, to Vanuatu, New
Caledonia, Fiji and New Zealand.
The
genus is especially valuable for two
reasons: firstly, its beautiful, high
value timber, and secondly its valuable
resin which is still used for many
varnishes and lacquers. It is also a
particularly challenging genus to
understand taxonomically. Most herbarium
specimens are sterile, the nomenclature
is famously confused, there is very
little morphological variation between
the species and next to nothing is known
about the phylogeny of the genus.
You can
find out more about the systematics of Agathis
by following the links to the left. If
you need a specimen identified, you can
either try and use my key (coming soon)
or e-mail me with details of the pollen
cone. Please note that sterile specimens
cannot be confidently identified! A
checklist of species currently recognized
with correct names and typification
details is available as the 'Taxonomy'
page.
I'm
presently working on the New Caledonian
species of Agathis, with a view
to applying molecular data to understand
species limits in this group, where
previous studies have relied entirely on
the morphology of the few fertile
collections. I've made hundreds of
collections of DNA samples, and dozens of
new herbarium collections for Oxford,
Nouméa and Kew, in the course of two
months of fieldwork in New Caledonia
earlier this year. You can read more
about the ideas that underpin this
approach by clicking on the 'Species'
link at the left hand side.
I hope
this website is of use, or at least of
interest, to you. If you have a query, a
suggestion for its improvement, or
anything obvious which is missing, please
do get in touch with me - contact details
as at the foot of this page. If you work
on any aspect of the biology or use of Agathis
I would love to hear from you.
