Easton's 1897 Bible Dictionary:

Gourd
   (1.) Jonah's gourd (Jonah 4:6-10), bearing the Hebrew name
   _kikayon_ (found only here), was probably the kiki of the
   Egyptians, the croton. This is the castor-oil plant, a species
   of ricinus, the palma Christi, so called from the palmate
   division of its leaves. Others with more probability regard it
   as the cucurbita the el-keroa of the Arabs, a kind of pumpkin
   peculiar to the East. "It is grown in great abundance on the
   alluvial banks of the Tigris and on the plain between the river
   and the ruins of Nineveh." At the present day it is trained to
   run over structures of mud and brush to form boots to protect
   the gardeners from the heat of the noon-day sun. It grows with
   extraordinary rapidity, and when cut or injured withers away
   also with great rapidity.

     (2.) Wild gourds (2 Kings 4:38-40), Heb. pakkuoth, belong to
   the family of the cucumber-like plants, some of which are
   poisonous. The species here referred to is probably the
   colocynth (Cucumis colocynthus). The LXX. render the word by
   "wild pumpkin." It abounds in the desert parts of Syria, Egypt,
   and Arabia. There is, however, another species, called the
   Cucumis prophetarum, from the idea that it afforded the gourd
   which "the sons of the prophets" shred by mistake into their
   pottage.
