Myriophyllum species are known as Water Milfoils and are members of the Haloragaceae family. Our skill at the taxonomy of this genus leaves a lot to be described. This article will describe Water Milfoils in general as they are very similar in appearance. Myriophyllums are freshwater aquatic plants whose distribution is cosmopolitan. There are about 69 species with Australia the centre of diversity with 37 endemic species and 5 naturalised.
Marsilea mutica, Banded Nardoo, is a member of the Marsileaceae family. There are about 65 species worldwide with 6 endemic to Australia.

Arching, grass-like leaves are light green up to 30 centimetres long. Each stem is crowned by a silvery spikelet (basically a small flower head).
Drosera hookeri, in common with all Sundews, is a carnivorous plant that traps insects on specialised hairs carried on the margins and upper surface of the leaves. The hairs are known as tentacles. The soluble parts of the prey are absorbed by enzymes released by the tentacles.
The common name of Thelychiton (Dendrobium) kingianum is ‘Pink rock orchid’ and as you can see, my species is a very dark pink coloured form and an outstanding reliable plant for any garden with a few rocks. This species occurs naturally along eastern Australia from just above Newcastle to the central Queensland highlands and grows naturally on rocky surfaces.
Dipodium punctatum, the Hyacinth Orchid is a leafless, terrestrial orchid. Usually one or two spikes carry up to 50 deep purplish-red hyacinth-like flowers. The photo shows an exceptional flowering with eight spikes growing close together. Summer is the peak flowering season.
Crassula helmsii, the Swamp Stonecrop, is an aquatic or bog plant. Plants may creep or float depending on the depth of water. Stems will reach a length of 30 centimetres.
