NATURAL HISTORY OF PLANTS. 



vertical furrow. They are perennial herbs, very aromatic, resembling 

 certain Ghcerophylla. One is European ; the leaves are decompound, 

 bi- or tripinnate. In a second species, from North America, type of 

 the genus Glycosma, the leaves are bi-. or tripiimate. 

 We unite to it as a section Osmorhiza, from the 

 same country as Glycosma, and similar to it, but 

 with very numerous vittae, sometimes very thin or 

 almost nil.

Analogous to the preceding genera, Scandix is 

 thought "to differ from them by its narrower and 

 more elongate fruit, prolonged above the cells in a 

 long slender beak surmounted by the stylopods and 

 styles (fig. 156). The carpels, nearly round, have 

 obtuse fidges and solitary vittse or none. They are 

 annual herbs of the north temperate zone of the old 

 world. The umbels are compound and the involucre 

 is -nil or formed of a single bract. The flowers are 

 most frequently polygamous. 



In Ottoa, a perennial plant of Columbia and 

 Mexico, the flowers and fruit are nearly those of Chcerophyllum ; the
