HOP (Houblon, Fr. ; Hopfcn, Gcr.) is the name of a well-known plant of the 

 natural family of Urticacca, and of the Dioecia pentandria of Linnaeus. The female 

 flowers, placed upon different plants from the male, grow in ovoid cones formed of oval 

 leafy scales, concave, imbricated, containing each at the base an ovary furnished with 

 two tubular open styles, and sharp-pointed stigmata. The fruit of the hop is a small 

 rounded seed, slightly compressed, brownish coloured, enveloped in a scaly calyx, thin, 

 but solid, which contains, spread at its base, a granular yellow substance, appearing to 

 the eye like a fine dust, but in the microscope they seem to be round, yellow, transparent, 

 grains ; deeper coloured, the older the fruit. This secretion which constitutes the use- 

 ful portion of the hop, has been examined in succession by Ives, Planche, Payen, and 

 Chcvallier. A pretty full account of the results of their researches in treating of tho 

 hop is given in the article BEER.
