with an inflexed point. Stamens incurved, not projecting beyond the 

 petals. Cremocarp i inch long, elliptical or oblong-ovoid, slightly 

 compressed, much longer and narrower than in the two preceding 

 species, deep chestnut-colour, witb the ridges pale and slender! 

 Styles short, retlexed, longer than the swollen stylopods. Plant 

 glabrous, dark-green. 



Great Mirth-nut. 



French, Terrenoix commune. German, Knollentragender Kiimmel. 



The roots of this plant are esculent, but until lately were supposed not to grow- 

 wild in Britain. It is called by the Italians Pancaseole, a name signifying bread and 

 cheese, the deficiency of which it supplies either raw or boiled, and somewhat resembles 

 the chestnut in flavour. 



GENUS XIIL—B UNIUM. B.C. 



Calyx -limb obsolete. Petals obovate, emarginate, with an 

 inflexed lobe. Cremocarp oblong-ovoid, attenuated towards the 

 apex ; columella bifid ; mericarps with 5 equal filiform ridges ; 

 interstices each with 2 or 3 vittre ; inner face channelled. Seed 

 channelled on the inner side (that towards the columella). Invo- 

 lucres none, or of few leaves. 



^ Plant with exactly the habit of the tuberous Cara, from which 

 it is artificially separated by the seed having a longitudinal furrow 

 on the inner side, on which account it is sometimes removed to the 

 Scandicineae ; but the furrow is much shallower than in that 

 tribe, and in other respects the plant agrees too closely with Carum 

 for so wide a separation. 



The origin of the name of this genus is possibly from the word jSowos (bounos), 

 a hill or elevated spot, the plant loving dry situations.
