Order XXXVII. UMBELLIFEE.^. 



Gal. 5-toothed or entire, adherent to the ovary, limb often 

 scarcely visible. Pet. 5, usually inflexed at the point. Stam. 

 o, inserted vrith the pet. round the stylopode. Ovary 2-celled, 

 crowned with a double fleshy disk (stylopode). Styles 2. Fr. 

 consisting of 2 carpels (mericarps) adhering by their face (com- 

 missure) to a common axis from which they ultimately separate 

 and become pendulous. Seed solitary, pendulous. Albumen 

 horny. — Inflorescence umbellate. .Estivation imbricate, except 

 in Hydrocotyle and Crithmum. — Each carpel has 5 primary, and 

 often 4 intermediate secondary ridges ; and in the substance of 

 the pericarp are usually linear receptacles of oil (vittse or stripes) 

 under the ridges or the spaces between them. These parts are 

 sometimes either wanting or only slightly apparent. The 

 stripes are " solitary " when there is only one in each space be- 

 tween the primary ridges, and " 2, 3, &c. together " when 2, 3, 

 or more occur in each space. They and the ridges are best seen 

 by making a horizontal section of the fruit.
