i like visiting the greenhouse in the hong kong park a lot, because of the thick moist green atmosphere in there and because it grows a lot of fern in it.
and one cannot miss appreciating the leaves of begoniaceae. they are of different shapes and have their different styles of marking and colours.

- begonia is a genus in the flowering plant family begoniaceae. the only other member of the family begoniaceae is hillebrandia, a genus with a single species in the hawaiian islands. the genus symbegonia is now included in begonia. “begonia” is the common name as well as the generic name for all members of the genus.
- the plants are monoecious, with unisexual male and female flowers occurring separately on the same plant, the male containing numerous stamens, the female having a large inferior ovary and two to four branched or twisted stigmas. in most species the fruit is a winged capsule containing numerous minute seeds, although baccate fruits are also known. the leaves, which are often large and variously marked or variegated, are usually asymmetric (unequal-sided).
