The Spikenard (_Nardostachys jatamansi_) belongs to the natural order _Valerianaceæ_. It is a wild plant of Bhutan found near Rangasnati, in India, and in ancient times it was transported on camels by the regular caravan route to Syria, Greece, and Rome. It was then worth about £3. 10s. per lb. The essence is obtained from the roots, but one hundred pounds of roots will furnish only half a pound of essence. Now it has but little value.[153]
