One day we walked up the Teesta to the Rumphiup river, a torrent from Mainom mountain to the west; the path led amongst thick jungle of Wallichia palm, prickly rattan canes, and the Pandanus, or screw-pine, called "Borr," which has a straight, often forked, palm-like trunk, and an immense crown of grassy saw-edged leaves four feet long: it bears clusters of uneatable fruit as large as a man's fist, and their similarity to the pine-apple has suggested the name of "Borr" for the latter fruit also, which has for many years been cultivated in Sikkim, and yields indifferent produce.
