OSMORHIZA. 133 



the teeth (ends of the sepals), which we might expect to see 

 as in the Apple flower, are obsolete or missing. The 5 small 

 petals are conspicuous for their snowy whiteness. The point 

 of each is abruptly inflected so as to make it appear notched 

 (emarginate) at the end. There are 5 stamens, inflected like 

 the petals. The two styles are prominent, slender, as long 

 as the stamens, gradually enlarged at the base into the ovary, 

 or rather into a disk which crowns it. The ovary is inferior, 

 i. e., adherent to the calyx tube which incloses it, 2-carpeled, 

 and 2-ovuled. 



The Fruit of this Tribe of plants is of curious structure, 

 and affords the best, often the only characters for distin- 

 guishing between the genera. In Cicely, its form is linear- 

 oblong, with a tapering base somewhat club-shaped, flattened 

 on the sides, crowned with the 2 styles. It finally splits into 

 2 carpels displaying a forked carpophore (p. 78) on which each 

 remains awhile suspended. The carpels are nearly terete, 

 the face being narrow, and the back with 3 linear, hispid 

 (with short stiff *hairs) ribs. This form of fruit is called 

 cremocarp (Gr. kremao, I hang, karpos, fruit). 



The Name, Osmorhlza (root-scented), as well as the spe- 

 cific term, 0. longistylis (long-styled), given to this plant, is 

 characteristic. Another kind of Cicely ( 0. brevistylis, short- 

 styled), growing in similar situations, will often be found 

 and mistaken for this. In the former, the styles are slender 

 and as long as the stamens : in the latter, conical and thrice 

 .shorter ; the leaflets more pointed and pinnatifid ; the bract- 

 lets long-pointed, and the root less agreeable in taste.
