146 NATURAL HISTORY OF PLANTS. 
assigned elsewhere, here become so variable that we may say they 
are nearly as often absent as present. The flowers are regular or 
irregular, with a valvate or imbricated calyx,’ and with or without a 
hypogynous or perigynous corolla. The stamens are free or in one 
or more bundles; the gynceum is central or excentric.” The fruit 
is dehiscent or indehiscent, containing one or many albuminous or 
exalbuminous seeds. The leaves are pinnate or bipinnate, stipulate 
or exstipulate. Some few characters are of altogether exceptional 
occurrence, such as simple or unifoliolate leaves,’ indefinite stamens,” 
diclinous flowers,’ and herbaceous stems. The last character is only 
found in several Cassias and in some Cesalpinias of the section 
Hoffmanseggia. 
In 1825, De Canpotie knew but thirty-four of the genera now 
retained in the group Cesalpiniee. He inserted three other types, 
the genera Aloexylum, Anoma,’ and Baryeylum® of Lourztro, which 
are still ill-known and of most doubtful position; besides the 
Dalbergiee, now referred to the sub-order Papilionacee. To the then- 
known genera R. Brown added Petalostyles in 1817, and he pub- 
} In our descriptions we always make it a 
point to distinguish as far as possible the calyx 
‘proper from the receptacular part of the flower. 
Thus, while BenrHam & Hooxer, following 
their predecessors, almost always describe a 
‘tubular or cupuliform part of the calyx con- 
sisting of a single piece and lined by the disk, as 
well as a free part above, often divided down to 
its base, we consider the former part, usually 
lined by the disk, as belonging to the receptacular 
axis. Hence from our view the calyx is far 
oftener dialysepalous in Cesalpiniee. 
? In this case we do not, like most authors, 
regard the gynzceum as adnate to the calyx- 
tube; but consider that owing to the irregular 
Aevelopment of the different parts of the floral 
weceptacle, its organic apex, which corresponds 
‘with the insertion of the gynzceum becomes 
‘more or less excentric, as in most Chrysobalanea, 
being more or less closely approximated to the 
zim of the cup, sac, or tube represented by the 
xeceptacle. Moreover the study of the develop- 
ment confirms this interpretation. (See Adan- 
sonia, vi. 187.)

buted one of the kinds of eagle wood or lign- 
aloes (bois d’aigle) of commerce (“ verum lignum 
Aloes largiens, Enpu.”); it is described as 
having simple alternate leaves, and flowers with 
four sepals, five and ten stamens. Its fruit is 
thus described: “ Legumen lignosum leve fal- 
catum l-spermum. Semen oblongum curvum 
arillatum.” This plant it seems cannot be 
identified in Cochinchina. Its organization 
brings it at once near to Copaifera, Cynometra, 
and Connaracee.
