SEM Photos and Data Table

We used a scanning electron microscope to take photos of three different lilies: the Asian Lily, Day Lily, and Easter Lily.  We included a picture of the pollen with highlighted apertures, colored with Seashore, and a picture at high magnification to show texture. This is what we found:

Asian Lily
Lilium amabile

Day Lily
Hemerocallis lilioasphodelus

Easter Lily

Lilium longiflorum

Pollen Data Table

Common Name	Scientific Name	Pollen Length x Width (μm)	Pollen Type	Number of Apertures	Surface Texture
Asian Lily	Lilium amabile	91.6 x 47.9	Monolete	One	Reticulate
Day Lily	Hemerocallis lilioasphodelus	131.0 x 50.5	Monolete	One	Reticulate
Easter Lily	Lilium longiflorum	78.8 x 41.2	Monolete	One	Reticulate

As you can see, lilies' pollens are reticulate monoletes.  To answer our question, we will have to explore both the identity of these flowers and other reticulate monoletes; fortunately, we will be able to use pictures from other peoples' blogs to compare their likeness.  We already know that Lilacs are very similar in appearance.  When we find more pollens that look like ours, we will post their pictures as well, and say whether or not they are closely related.
