  • Immature leaves and stems, which were about one to three centimeters nearby the stem tips, of Blumea balsamifera (L.) DC. (BB) and Blumea laciniata (Roxb.) DC. (BL) were cut into sections under ?18?C with a frozen section machine, and observed under an optical microscope. Results show that the most significant difference is that the BB has only one kind of glandular trichomes, while the BL has two. The glandular trichomes found on BB terms were all short glandular hairs (SGH), which were not longer than 100 μm. On BL stems, besides the SGH, the long glandular hairs (LGH), which were longer than 200 μm, were also found. By the factors pointed out in present study, the BB and BL and be distinguished from each other.
