It is difficult to separate clearly from Pimpinella, that is from Carum, Bulbocastanum, herbs with a tuberous root or rhizome, in which the bracts of the involucres and Sison Amomum. involucels are often but not constaTitly wanting, and which have a fruit generally more oblong with mericarps subcylindrical or slightly compressed at the sides, at- tenuate at the summit. The vittse are numerous, continuous or interrupted, very distinct or very thin, and the face of the seed is concave or traversed by a deep ' furrow. These plants inhabit temperate Europe, Western Asia, and the north of Africa. Sison Amomum (fig. 122) is also a very Fig. 122. Fruit (?). near neighbour of Garum, with a short, almost didymous fruit, and it is to Carum what Heraclium is to Peucedanum; for its vittse, wide and solitary in each furrow, occupy only a variable extent of the upper portion and terminate in a point or in a mass. It is an annual or biennial herb of Europe. Amnd is also very analogous to the Caraways. The calyx is but little developed or nil; the stylopods are conical or depressed; and.
