SCROPHULARIACEÆ.
Picrorhiza Kurrooa, Royle.
A small perennial herbaceous plant found in Kemaon, at Gossain-than, and other parts of the Himalayan mountains, where its roots, which are called "Hooling" in Tibet, and have a powerful bitter taste, are used as a febrifuge by the natives, and also sent down to the bazaars of Bengal, where they form one of the many bitter roots sold under the name of "Teeta." The plant grows about six inches high, and has scarcely any stem, its leaves all rising from the summit of the thick root, and also its flower-stalks, which are five or six inches high, and bear a dense spike of small bluish flowers at the top.
Herpestis Monnieria, Humb. (= Gratiola Monnieria, Linn.)
The Cinghalese consider this plant to possess febrifuge virtues: they call it "Loonoo Weela." In India its expressed juice is mixed with petroleum, and used as a topical application in rheumatism. It is a little creeping plant, common in moist places throughout the tropics of both hemispheres, and has obovate-cuneate leaves, bearing solitary long-stalked pale-blue flowers in their axils. The Bengalese call it "Adha birni," and the Telingas "Sambrani-chittoo."
ACANTHACEÆ.
Andrographis paniculata, Nees ab Essen. (= Justicia paniculata, Burm.).
