Getting to know Ixoras
Ixora is a large genus comprising about 400 species of
evergreen trees and shrubs in tropical Africa, Asia, Australia and the
islands of the south Pacific. Ixora and some of the popular
garden plants such as Gardenias, Mussaendas and important crops like
Morinda (noni) and Coffea arabica (coffee) belong to the same Rubiaceae
family. In Peninsular Malaysia, in addition to the cultivated species,
there are some 20 wild species of mainly shrubs or small trees and
rarely as large trees. Flowering is seasonal in the wild species with
preference for light shaded habitats in the lowland forests and
mountains or near rivers and streams.
Interestingly “the name Ixora is a Portuguese rendering of the
Sanskrit name of the Indian god Siva” and synonymous with Iswara, a
Malabar deity. Contrary to the divine names, the Malays call it
pecah periuk referring to the four petals which resemble a broken
earthenware pot. They must have referred to the ‘more rounded petals’
of the cultivated Ixora coccinea at the time! Sometimes it is known as
jarum-jarum or jejarum referring to the unopened flower buds and the
projecting styles of the open flowers which resemble bunches of
needles. In this respect, from a distance or at a glance, Carphalea, an
old favourite becoming popular again may be confused with Ixoras.
Closely related genera with relatively similar flowers as Ixoras
include Pavetta and Pentas.
Garden, Mosquitoes & Dengue
Gardens, mosquitoes and dengue, a continuous concern
especially those who live in urban and suburban areas. While we are
excited about having gardens we should be aware of the danger of dengue
which is a mosquito-borne viral disease, and mosquitoes are not
uncommon in gardens. We hope the following information will benefit the
readers and all garden enthusiasts.
Phytotelmata
In many gardens, there may be plants that will provide suitable
breeding sites for mosquitoes. These come in the form of phytotelmata
(singular phytotelma), that is, non-aquatic plants that impound water.
They include leaf axils, inflorescence, modified leaves, stem holes or
depressions, fallen leaves and open fruits. Some examples are
bromeliads, bananas, taro, gingers, Dillenia suffruticosa (simpoh), and
Ficus auriculata (Ficus roxburghiana; ara).
The leaf axils and inflorescences are often overlooked as potential
breeding sites for mosquitoes. Examples of mosquitoes breeding in leaf
axils include members of the genera Aedes, Culex, Topomyia,
Toxorhynchites, Tripteroides and Uranotaenia.
