can u help me determine if they are rare species or not?

can u tell me which species are rare and which is not?

Not sure if I can answer all of them.

The following are common species (growing in a wide range of countries or habitats. So the following listed species are NOT rare:

Panicum maximum (grass)
Haematoxylum campechianum (tree)
Waltheria indica (plant), found throughout the tropics
Agave sp. grown for tequila, or available at the garden center
Heteropogon contortus; grass, a weed (too much of this one!)
Crab grass (Digitaria): lawn pest
Portulaca oleracea: a weed
Phyllanthus debilis; a weed
Leucaena leucocephala; tree, spreads as weed
Stapelia gigantea, succulent; can buy this plant at nurseries

I am not sure about the rest, but it looks as if the majority of your list are definitely NOT rare!

Lichen is not really a species, but rather a symbiosis of a fungus with a photosynthetic partner such as a alga. They are not rare, but sensitive to pollutants, and so they won’t grow in places with a lot of pollution.
