. The natural history of plants. Botany. TJMBELLIFERM. 131. Kg. 140. Long. sect, of fruit (I). and solitary vittse in the interposed furrows. They are glabrous perennial herbs, European and oriental, with decompound ternati- pinnate leaves and compound umbels, furnished with involucres and involucels formed of numerous bracts. The seeds are concave on the face, in which the raphe is sunk. Molopospermum (fig. 141) has nearly all the characters of Physospermum, especially in the organs of vegetation; but in the fruit, more elongate, constricted also at the com- missure, the primary ridges are very unequally developed. The two mar- ginal are reduced to very small dimen- sions, whilst the dorsal and the two latero-dorsal alone project in the form of prisms with a blunt independent angle; which gives the transverse section of each mericarp a trapi- zoidal form. The vittse are solitary and well developed, and the seed there has deep canals. The , -nr ^ 1 /Ti/r Molopospermum cicutarium. only Molopospermum known (M. cicutarium) inhabits Central and Southern Europe. Smyrnium holds an intermediate position between Molopospermum and Physospermum by the promi- nence of its primary ridges. The two marginal are often little developed at the commissure, which is more or less hollowed. The fruit (fig. 142-144) is gene- rally short, or even wider than long, with numerous vittse. The face of the seeds is concave and the margin generally invo- lute. They are biennial plants of Europe, the Levant and Northern Africa, glabrous, having compound umbels with involucres and involucels nil or reduced to a few bracts. We can distinguish K 2.
