Charles Darwin believed that nyctinasty exists to reduce the risk of plants freezing. [13] Nyctinasty may occur to protect the pollen, keeping pollen dry and intact during the nighttime when most pollinating insects are inactive. [14] Conversely, some flowers that are pollinated by moths or bats exhibit nyctinastic flower opening at night. [14]
An upper pitcher of Nepenthes lowii, a tropical pitcher plant that supplements its carnivorous diet with tree shrew droppings. [1] [2] [3]Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods, and occasionally small mammals and birds.
Mimosa pudica (also called sensitive plant, sleepy plant, [citation needed] action plant, humble plant, touch-me-not, touch-and-die, or shameplant) [3] [2] is a creeping annual or perennial flowering plant of the pea/legume family Fabaceae. It is often grown for its curiosity value: the sensitive compound leaves quickly fold inward and droop ...
However, it is not known whether the digestive enzymes were produced by the plant itself or surface microbes. [5] Additionally, some definitions of carnivory require the plant to gain some tangible benefit in capturing and digesting prey, such as increased seed yield or growth. Such an experiment has not been done with this species.
Darlingtonia californica / d ɑːr l ɪ ŋ ˈ t oʊ n i ə k æ l ɪ ˈ f ɔːr n ɪ k ə / —also called the California pitcher plant, the Oregon pitcher plant, cobra lily or cobra plant—is a species of carnivorous plant in the new world pitcher plant family, Sarraceniaceae. It is the sole species within its monotypic genus, Darlingtonia.
This list of carnivorous plants is a comprehensive listing of all known carnivorous plant species, of which more than 750 are currently recognised. [1] Unless otherwise stated it is based on Jan Schlauer's Carnivorous Plant Database Archived 2016-09-18 at the Wayback Machine. Extinct taxa are denoted with a dagger (†).
Despite being carnivorous, their flowers are insect-pollinated, typically with white to purple flowers that close at night. They produce small seeds that are dispersed by wind and water. [3] Most of the members of Droseraceae are contained in the genus Drosera, the sundews. Both Dionaea and Aldrovanda have only one extant species.
The plants that bear such flowers can be tall, columnar, and sometimes extremely large and tree-like, but more frequently are thin-stemmed climbers. While some night-blooming cereus are grown indoors in homes or greenhouses in colder climates, most plants are too large or ungainly for this treatment and are only found outdoors in tropical areas.
