and become pendulous. Seed solitary, pendidous. Albumen 
horny. — Inflorescence umbellate. — Each carpel has 5 primary, 
and often 4 intemiediate secondary ridges ; and in the substance 
of the pericarp are usually linear receptacles of oil (vittae or 
stripes) under the ridges or the spaces between them. These 
parts are sometimes either wanting or only slightly apparent. 
The stripes are "solitai-y " when there is only one in each space 
between 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.
