【 摘 要 】

Palynology, the study of pollen, had a big role in paleontology, archeology, and forensics. Pollens from different plants had different morphology, such as in Liliaceae. Scanning electron microscopy (SEM) was applied to observe the morphology of Liliaceae pollens. This study aimed to determine the pollen grains morphology and morphometry in Liliaceae. The descriptive qualitative research was used five different species from three genera as the sample, namely Hemerocallis fulva, Hemerocallis lilioasphodelus, Aloe vera, Lilium longiflorum, and Lilium candidum. Parameters measured in this study were the types of pollen sizes, pollen shape, aperture characteristic, and ornamentation type of exine. The results showed that in Liliaceae had various shapes of pollen grains, i.e., prolate (1.33-2 μm) and per-prolate (≥ 2 μm), as well as the pollen grains size, from minuta (10-25 μm in diameter) to medium (25-50 μm in diameter). Aperture characteristic of the pollen grains was monocolpate which has one colpus, and the ornamentation type of exine was reticulate patterns.
