TOOTHWORT , the popular name for a small See also:

British plant of curious See also:form and growth, known botanically as Lathraea squamaria. It grows parasitically on roots, chiefly of See also:hazel, in shady places such as hedge sides. It consists of a branched whitish underground See also:stem closely covered with thick fleshy colourless leaves, which are See also:bent over so as to hide the under See also:surface; irregular cavities communicating with the exterior are formed in the thickness of the See also:leaf. On the inner See also:wall of these See also:chambers are stalked hairs, which when stimulated by the See also:touch of an See also:insect send out delicate filaments by means of which the insect is killed and digested. The only portions that appear above ground are the See also:short See also:flower-bearing shoots, which See also:bear a spike of two-lipped dull See also:purple See also:flowers. The scales which represent the leaves also secrete See also:water, which escapes and softens the ground around the plant. Lathraea is closely allied to another British parasitic plant, broomrape (Orobanche).
