pubescence
Botanical term for the fine, soft hairs on plant surfaces such as leaves and stems.
The leaves of this plant are densely covered with pubescence.
Hair removal does not make vellus hair thicker.
Compound of 軟 (nan, 'soft') and 毛 (mō, 'hair'). The reading is on'yomi, suggesting a Sino-Japanese origin, likely coined in medical or scientific contexts.
