Microscope Slides



These are ermanently mounted, stained sections (cross-sections, longitudinal sections, serial sections, etc. of reproductive structures and/or vegetative anatomical preparations), and either partial or whole specimens (e.g., an entire small epiphytic alga) mounted on microscope slides. There are currently 8,391 specimens on microscope slides in the Microscope Slide collection, not including the Diatom collection (28,775 specimens) which is primarily specimens mounted on microscope slides.

lide box The US National Herbarium maintains permanently mounted, stained sections (cross-sections, longitudinal sections, serial sections, etc. of reproductive structures and/or vegetative anatomical preparations) and either partial or whole specimens (e.g., an entire small epiphytic alga) mounted on microscope slides. The mounting material used varies, as many slides are sent with accompanying herbarium sheets for accession to the herbarium. Slides prepared at the museum are made using the Karo syrup method as described under Collection and Preservation Techniques for Algae.

This collection is referenced from the main collection where either a dummy sheet, or a sheet holding a pressed specimen is annotated to reference the slide-mounted material. The collection itself is sequentially numbered and is housed in wooden slide boxes stored in metal cabinets adjacent to the main herbarium.
