  • A poison-yielding tree of Java.

  • "I have no hope for myself or for others. Our life is a false nature; it is not in the harmony of things; it is an all-blasting upas, whose root is earth, and whose leaves are the skies which rain their poison-dews upon mankind."

  • This is one of the most famous trees in Russian literature, thanks to Aleksandr Pushkin's chilling poem "Anchar" ("The Upas Tree", 1828). I was able to find a readable translation on the Internet, but unfortunately no reliable information about the translator. Perhaps the most famous lines from this poem are:

    �?о человека человек

    По�?лал к анчару �? вла�?тным взгл�?дом…

    No cheloveka chelovek

    Poslal k ancharu s vlastnym vzglyadom…

    which I would translate unpoetically as "But with a domineering look one man sent another man to the upas tree…"

    But here is the uncredited translation I found:

    The Upas Tree

    Deep in the desert's misery,

    far in the fury of the sand,

    there stands the awesome Upas Tree

    lone watchman of a lifeless land.

    The wilderness, a world of thirst,

    in wrath engendered it and filled

    its every root, every accursed

    grey leafstalk with a sap that killed.

    Dissolving in the midday sun

    the poison oozes through its bark,

    and freezing when the day is done

    gleams thick and gem-like in the dark.

    No bird flies near, no tiger creeps;

    alone the whirlwind, wild and black,

    assails the tree of death and sweeps

    away with death upon its back.

    And though some roving cloud may stain

    with glancing drops those leaden leaves,

    the dripping of a poisoned rain

    is all the burning sand receives.

    But man sent man with one proud look

    towards the tree, and he was gone,

    the humble one, and there he took

    the poison and returned at dawn.

    He brought the deadly gum; with it

    he brought some leaves, a withered bough,

    while rivulets of icy sweat

    ran slowly down his livid brow.

    He came, he fell upon a mat,

    and reaping a poor slave's reward,

    died near the painted hut where sat

    his now unconquerable lord.

    The king, he soaked his arrows true

    in poison, and beyond the plains

    dispatched those messengers and slew

    his neighbors in their own domains.

    (2) Kettish, putrid. It may be said of meat gone too far, "It's very kettish."
