Examination under the microscope, on the other hand, can
assess whole, fragmented, or powdered plant material, including
characteristic hairs (e.g. glandular or stellate), cell types, fibres
and granular objects (e.g. starch grain, calcium oxalate crystals),
as well as minute floral and fruit characteristics.
Microscopic characteristics of the most important plants have been described,
but today professional microscopists trained in the analysis of
botanical materials are rare, and published reference standards
are not easy to access.
