Sterculiaceae (Cacau Family)
Cacau (
Theobroma cacao
)
0054 This species is well known, as the seeds are the source
of chocolate. The sweet, aromatic pulp around the
seeds is eaten by local peoples. The exact origin of the
cacau is uncertain, since it was so widespread in pre-
Colombian times, but it possibly came from north-
western Amazonia. The large fruits are borne on the
trunk and branches of the trees. They are either ellips-
oid or round. The rounder fruits are termed the criolo
variety. The thick hard outer shell is yellow or
red. The edible pulp surrounds 20–40 round seeds
arranged in five rows.
Cupuac¸ u
´
(
Theobroma grandiflorum
)
0055 This species of the cacau genus is cultivated for the
aromatic pulp of its most delicious fruits. The small
trees produce large ellipsoid football-like fruit 12–25
10–12 cm that can weigh up to 1.5 kg. The exterior
has a rust colored scaly covering. Inside, the 20–50
seeds are in five rows and adhere strongly to the thick
pulp. The pulp is very popular in Brazil as an ice-
cream flavor and for other sweets. The seeds have
recently started being used to make cupulate, which
tastes much like chocolate but has a different fatty
acid profile. The tree is a native of eastern Amazonia,
where the fruits are also harvested from wild trees.
0056 The fruits of several other species of Theobroma are
used locally for the pulp, especially the cacau sacha (T.
speciosum) in Peru. Theobroma bicolor or macambo
is commonly cultivated by indigenous peoples of the
upper Amazon in Peru for the flat, disc-like seeds,
which are roasted and eaten like nuts. This species is
widely cultivated from Mexico to Brazil.

Introduction
0001Tropical rain forests of South-east Asia in general, and
that of the Indo-Malayan region in particular, are
known to endow a tremendous variety of plant genetic
resources. These include species of valuable and mar-
ketable timber species, medicinal plants, and fruit tree
species. Many fruits originated from the Malaysian
forest. However, out of this wide range of fruits,
many are considered rare or lesser-known. They are
generally neglected because they have not been ex-
ploited commercially and there is a lack of improved
varieties. They occur in the wild or grown in scattered
home gardens. These rare fruit species are also a source
of useful genes for related crop species and promise to
add to both nutrition and economic development.
0002Tropical fruits have been recognized as a rich and
natural source of vitamin A and vitamin C, potassium
and high dietary fiber. Fruits such as guava (Psidium
guajava) contain 150 mg 100 g
1
vitamin C. Jackfruit
(Artocarpus heterophyllus) and cempedak (Artocar-
pus integer) are highly nutritious and they are a very
valuable carbohydrate source. The seed also has
plenty of carbohydrates, as well as a fairly high pro-
tein content. The nutritional value of many more
tropical fruits is not well documented.
0003Table 1 shows some examples of the lesser-known
species. A more detailed outline is given below on 12
of the fruits listed in Table 1.
Artocarpus odoratissimus
(Terap, Tarap,
Marang)
0004The terap fruit is a syncarpium, a multiple fruit with
numerous carpels fused with the fleshy receptacle.
The rind is a mass of closely packed soft spines
about 2 cm long with a small nob. It is green when
immature and becomes fig-brown and soft when
ready to eat. The numerous seeds are embedded in a
firm white flesh closely packed together and lightly
attached to the central core (receptacle).
0005Terap is unique to Brunei Darussalam and parts of
Sabah and Sarawak in Borneo. Although the fruit was
described from and better known in the Philippines,
its distribution there is limited and it was probably
introduced from Borneo. In the Philippines, the
species occurs only cultivated, but in Borneo it is
common in the wild state. The large fruit is esteemed
