Volunteer Park Conservatory different "Tillandsia" species. The conservatory also displays terrestrial species of the bromeliad family, such as the pineapple (Ananas comosus). A fern is any plant classified in the phylum or division Pteridophyta (also known as Filicophyta), a group composed of roughly 20,000 species. The conservatory's collection features a number of cycads. Other featured plants in the Fern House include a Mexican breadfruit ("Monstera deliciosa") and tropical flowers including passionflower ("Passiflora" sp.) and hibiscus. This house also features bog gardens with a collection of carnivorous plants including Venus fly traps ("Dionaea muscipula"), sundews ("Drosera" sp), pitcher plants ("Sarracenia" sp).

1000 Plant Genomes Project based on the expression level (how many mRNA molecules it produces). This means that highly expressed genes get better coverage because there is more sequence to work from. The result, then, is that some important genes may not be reliably detected by the project if they are expressed at a low level yet still have important biochemical functions. Many plant species (especially agriculturally manipulated ones) are known to have undergone large genome-wide changes through duplication of the whole genome. The rice and the wheat genomes, for example, can have 4-6 copies of whole genomes (wheat) whereas animals typically only have
