I am amazed by his wealth of knowledge and experience and was in awe of the beautiful photos he took over the years and showed on the screen for our viewing. It came as no surprise that he featured a lot of bromeliads, known as broms in short, especially since he is a well-known authority on this plant group in the botanical community. Midway through the talk, I realized I didn't take any notes and decided to record some pointers for my own noting. They are briefly as follows:
- Hemi-epiphyte - I mentioned this term before in some of my posts and refers to plants e.g. strangling figs, that begin its life as an epiphyte by growing on another plant such as a tree and which eventually sends its roots down to the ground and grow into a self-supporting plant on its own.
- Tank bromeliad - This refers to the group of bromeliads e.g. Neoregelia species, with broad leaf bases that overlap each other in a rosette to form a central reservoir, sometimes referred to as an urn or a cup, that functions as a receptacle that collects water, leaf-litter, decaying animals etc. These broms are often excellent biodiversity multipliers.
- Bodiversity multiplier - This is the first time I heard this term. The tank broms are regarded as such because their central reservoir of water is an ecosystem on its own and supports a multitude of living organisms up the food chain and web, from the microscopic bacteria and protozoan to the worms, insects, crustaceans, frogs, birds, snakes and so on.
- Pteridophyte - This refers to a specific group of vascular plants that do not produce flowers or seeds. These plants are very specialized and reproduce themselves via spores. Ferns and mosses belong to this group. Some common examples of pteridophytic epiphytes include the Bird Nest Fern, Stag Horn Fern.
- Broms with large inflorescence of warm coloured flowers - The pollinators of these broms with red and orange-coloured flowers are usually small birds e.g. hummingbirds, sunbirds, which are attracted by the showy colours to visit the flowers for their nectar.
- Aeschynanthus is from the Old World and Columnea is from the New World - I have always wonder how we can distinguish between the two easily and today I was rewarded as an attentive listener! It is the first time that I realized that they come from two different worlds. The latter is bird pollinated and its flowers are two-lipped as in typical hummingbird or sunbird pollinated flowers.
- Medinilla magnifica - I was reminded of this beautiful epiphyte that is often planted as a ground shrub instead. I first saw photos of it as an epiphyte in the book Tropical Garden Plants and wanted to try planting it on tree forks for years but never got to actually do it. I feel very tempted to try it now.
- Broms evolution - Broms are finely attuned to its habitat, which strongly influences its morphological evolution into many different forms e.g. narrow leaves, broad leaves.
