CREMOCARP— CYPSELA—-GLANS— -DIPLOTEGIA, 319 
Division 2. Inferior Syncarpous Fruits. 
ad. WITH A DRY INDEHISCENT PERICARP. 
1. The Cremocarp is an inferior, dry, indehiscent, two-celled, 
two-seeded fruit. The two cells or halves of which this fruit is 
composed are joined face to face to a common axis or carpophore, 
from which they separate when ripe} but to which they always 
remain attached by a slender cord which suspends them (jiy. 
717). Each half-fruit is termed a hemicarp or mericarp, and 
the inner face the commissure. Each por- 
tion of the fruit resembles an ach:enium, Fic. 717. 
except in being inferior; hence the name 
diachenium has been given to this fruit. 
Examples of the cremocarp as above defined 
are found universally in the plants of the 
order Umbelliferze, but in no other order. 
By Lindley, the definition of cremocarp is 
extended so as to include fruits of a similar 
nature, but which contain more than two 
cells, as, for instance, those of Aralia. 
2. The Cypsela.—This differs in nothing 
essential from the achzenium, except in 
being inferior and of a compound nature ,,, 
(see Bae 292). It occurs in all plants of the ap re roy a 
order Composite. When the calyx is pappose 
it remains attached to the fruit, as in Salsafy and Dandelion. 
3. The Glans or Nut is an inferior, dry, hard, indehiscent, 
one-celled, one or two-seeded fruit, produced from an ovary of 
two or more cells, with one or more ovules in each cell, all of 
which become abortive in the progress of growth except one or 
two (page 296). The three layers constituting the pericarp of 
the nut are firmly coherent and undistinguishable, and the 
whole is more or less enclosed by a cupule. The Acorn (fig. 
400), and the Hazel-nut (fig. 401), may be taken as examples. 
By some botanists the fruit of the Cocoa-nut Palm is called a 
nut, but this differs in being superior, and in its pericarp 
presenting a distinction into epicarp, mesocarp, aud endocarp. 
(See Drupe, page 311.) Such a fruit is better described as nut- 
like.

b. WITH A DRY DEHISCENT PERICARP. 
1. Diplotegia.—This is the only kind of inferior fruit which 
presents a dry dehiscent pericarp. It has already been stated 
under the head of Capsule (page 317), that the diplotegia differs 
in nothing from it, except in being inferior. The species of Iris 
(fig. 712) and Campanula ( figs. 687 and 688) are examples of 
this fruit. The diplotegia may open either by pores (fig. 688),
