Classed as a dicotyledon, leaves not parallel veined.
Fragrant flowers. Fruit is very acid with some culinary uses similar to lemons and limes. Can be considered as a flowering plant but more generally treated as a foliage plant.

Recent Research Findings:
The not so recent but important research findings of Ben-Jaacov et al. (1984) showed that this species could be stored at 54F in the dark for two weeks with no loss in quality upon removal or during subsequent interior use. Additionally, the plants could be packed and stored in a horizontal position to increase packing density by 50% with no loss in quality compared to plants packed in the normal vertical position.
