or PAPA-TREE. See Carica.—This tree Paper. is male and female upon different roots: the flowers of the former are white, and of the latter yellowish. The tender buds of these last are preserved into sweetmeats; and the long mango-popo, which is said to be little inferior to an East India mango, into pickles. When nearly ripe, the fruits are likewise boiled and eaten with any kind of flesh-meat, care being taken previously to cleanse them of the milky corrosive juice contained in them, which is of so penetrating a nature, says Hughes, that if the unripe fruit, when unpeeled, is boiled with the toughest old salt meat, it will soon make it soft and tender; and, if hogs are for any considerable time fed with the raw fruit, it wears off all the mucous slimy matter which covers the inside of the guts; and would in time, if not prevented by a change of food, entirely lacerate them. This juice, according to Linnaeus, is sometimes made use of to cure ring-worms and such cutaneous eruptions. It must be expelled by the medium of salt-water before the fruit is fit for use. It is remarkable, that the stalk of this plant is herbaceous and hollow; which last attribute has passed into a proverb in Barbadoes and other West India islands, where it is common to characterise a dissembler, by saying, that he is as hollow as a popo.
