A microscopic view of granules of daylily pollen, captured via the use of a Foldscope. The distinct boundary captured in the photo is the edge of the tape used to adhere the cover slip to the microscope slide.
The daylily from which the pollen was extracted, seen near the east side of the Parsons-Gates building at the California Institute of Technology. The daylily protrudes from a large, radially spreading clump-like base plant.
A closer view of the daylily from which the examined pollen was extracted.
A photo of granules of pollen extracted from a daylily, a daylily located near the east side of the Parsons-Gates building at the California Institute of Technology, located in Pasadena, CA. The sample was obtained via utilization of a cotton swab to extract the pollen via adhesion from a stamen of the flower, a process performed at 9:06 PM on May 10, 2019. The photos of the examined pollen were taken at approximately 11:03 PM on May 10, 2019.
In the image captured via observation of the pollen under a Foldscope, the particles of pollen not visible to the naked human eye are illuminated and the granule-like nature of pollen is elucidated. The small granules are especially visible in the lower half of the image, appearing to vary greatly in size and display somewhat of a clumping in regions of the photo. The distinct boundary captured in the photo is the edge of the invisible tape used to adhere the cover slip to the microscope slide, holding the pollen in place for observation. As such, the top portion of the photo is blurred due to the tape’s interference.
This flower likely belongs to the genus Hemerocallis , or daylilies, a postulation made by observation of the presence of six tepals (three petals and three sepals), the absence of a cup-shaped corona as would be present in a member of the Narcissus genus (daffodils), and the two-lobed nature of the anthers of the stamens of the flower. This particular flower may be of the species Hemerocallis lilioasphodelus, or yellow daylily, a postulation made by observation of the spreading plant from which the flower grows.
