are niches for the numerous seeds. These (figs. 128, 129), which 
constitute the serviceable part of the Cacao tree, are irregularly 
ovoid and enclose under their coats a large embryo with short 
conical radicle hidden between the cotyledons which are thick, 
fleshy, corrugated and folded upon themselves, and between whose 
folds the albumen is scarcely represented by some mucous ru- 
diments sometimes even wholly absent. Besides the common 
species the genus includes four or five others, all natives of tropical 
America! These are trees or shrubs, with simple alternate petiolate 
leaves, accompanied by two small lateral caducous stipules. Their 
flowers are solitary, or arranged in racemose cymes growing in the 
axil of the existing leaves, or more frequently upon the wood of the 
trunk, and of the old branches, and in the axils of fallen? leaves. 
Under the generic name of Herrania three or four Cacaos have 
been distinguished, whose petals, occasionally very long, are linear 
and involute-circinate in the bud, and whose leaves are compound- 
digitate, so that this genus scarcely deserves to be preserved. 
Beside it, on account of having multiovulate cells and fertile stamens, 
not solitary, the six following genera are placed in this subseries :— 
Guazuma, which generally has petals with linear bifid limb, two or 
three fertile stamens in each bundle, a muricate fruit, and seeds with 
fleshy albumen; Scaphopetalum, which has obovate-cucullate petals, 
without apiculate leaf, and ternate anthers, sessile upon the urceolus of 
the androceum, in the interval of the staminodes ; Leptonychia, which 
has short and concave petals, and fertile stamens grouped in pairs, 
accompanied outside by one or several sterile stamens; Aéroma, which 
has petals analogous to those of Theobroma, with superposed bundles, 
each formed of from two to four fertile stamens, and a membra- 
nous capsular fruit; finally, M/azwellia, which greatly resembles 
the Lasiopetalee by its very small glanduliform petals, but 
which has double fertile oppositipetalous stamens, an ovary with 
incomplete cells, and a woody indehiscent fruit with longitudinal 
wings.
