ORGANOGRAPHY. 
BOOK I. 
Many-celled, many-seeded, superior, indehiscent ; indurated or woody exter- 
nally, pulpy internally. 
Exa7nj)les. Omphalocarpus, Adansonia, Crescentia. 
B. Pericarpium fleshy. 
XXI. Tryma. — (Tryma, Watson.) 
Superior, by abortion one-celled, one-seeded, with a two-valved indehiscent 
endocarpium, and a coriaceous or fleshy valveless sarcocarpium. 
Exumjde. Juglans. 
XXII. NucuLANiuM. — (Nuculanium, Rich; B^ccsl, Desvaux.) 
Two or more celled, few or many-seeded, superior, indehiscent, fleshy, of 
the same texture throughout, containing several seeds, improperly called 
nucules by the younger Richard. This differs scarcely at all from the berry, 
except in being superior. 
Examples. Grape, Achras. 
XXIII. Hesperidium. — (Hesperidium, Desv. Rich.) 
Many-celled, few-seeded, superior, indehiscent, covered by a spongy separ- 
able rind; the cells easily separable from each other, and containing a mass of 
pulp, in which the seeds are imbedded. The pulp is formed by the cellular 
tissue, which forms the lining of the cavity of the cells ; this cellular tissue is 
excessively enlarged and succulent, is filled with fluid, and easily coheres into 
a single mass. The external rind is by M. De CandoUe supposed to be an 
elevated discus of a peculiar kind, analogous to that within which the fruit of 
Nelumbium is seated ; and perhaps its separate texture and slight connexion 
with the cells of the fruit seem to favour this supposition. But it is difficult 
to reconcile with such an hypothesis the continuity of the rind with the style 
and stigma, which is a sure indication of the identity of their origin ; and it is 
certain that the shell of the ovarium and the pericarpium are the same. The 
most correct explanation of this structure is to consider the rind a union of the 
epicarp and sarcocarp, analogous to that of the drupa. 
Example. Orange. 
Sect. 2. Fruit inferior. 
A. Pericarpium dry. 
XXIV. Glans (Glans, Linn., Desv. ; Calybio, Mirb. ; Nucula, Desvaux), 
fig. 165. 
One-celled, one or few-seeded, inferior, indehiscent, hard, dry ; proceeding 
from an ovarium containing several cells and several seeds, all of which are 
abortive but one or two ; seated in that kind of persistent involucre called 
a cupule. The pericarpium is always crowned with the remains of the teeth 
of the calyx ; but they are exceedingly minute, and are easily overlooked. 
Sometimes the gland is solitary, and quite naked above, as in the common oak ; 
sometimes there is more than one completely enclosed in the cupule, as the 
beech and sweet chestnut. 
Examples. Quercus, Corylus, Castanea. 
XXV. Cypsela (Akena, Necker ; Akenium, Rich.; Cypsela, Mirb.; Ste- 
phanoum, Desv.), fig. 148, 149. 
One-seeded, one-celled, indehiscent, with the integuments of the seed not 
cohering with the endocarpiuin ; in the ovarium state evincing its compound 
nature by the presence of two or more stigmata ; but nevertheless unilocular
