Delissea
The Hawaiian lobelioids are a group of flowering plants in the bellflower family, Campanulaceae, subfamily Lobelioideae, all of which are endemic to the Hawaiian Islands. This is the largest plant radiation in the Hawaiian Islands, and indeed the largest on any island archipelago, with over 125 species. The six genera involved can be broadly separated based on growth habit: ''Clermontia'' are typically branched shrubs or small trees, up to tall, with fleshy fruits; ''Cyanea'' and ''Delissea'' are typically unbranched or branching only at the base, with a cluster of relatively broad leaves at the apex and fleshy fruits; ''Lobelia'' and ''Trematolobelia'' have long thin leaves down a single, non-woody stem and capsular fruits with wind-dispersed seeds; and the peculiar ''Brighamia'' have a short, thick stem with a dense cluster of broad leaves, elongate white flowers, and capsular fruits. The relationships among the genera and sections remains unsettled . Many species have beauti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Campanulaceae
The family Campanulaceae (also bellflower family), of the order Asterales, contains nearly 2400 species in 84 genera of herbaceous plants, shrubs, and rarely small trees, often with milky sap. Among them are several familiar garden plants belonging to the genera ''Campanula'' (bellflower), '' Lobelia'', and ''Platycodon'' (balloonflower). '' Campanula rapunculus'' (rampion or r. bellflower) and ''Codonopsis lanceolata'' are eaten as vegetables. '' Lobelia inflata'' (indian tobacco), '' L. siphilitica'' and '' L. tupa'' (devil's tobacco) and others have been used as medicinal plants. '' Campanula rapunculoides'' (creeping bellflower) may be a troublesome weed, particularly in gardens, while '' Legousia'' spp. may occur in arable fields. Most current classifications include the segregate family Lobeliaceae in Campanulaceae as subfamily Lobelioideae. A third subfamily, Cyphioideae, includes the genus '' Cyphia'', and sometimes also the genera '' Cyphocarpus'', '' Nemacladus'', '' ...

Lobelioideae
Lobelioideae is a subfamily of the plant family Campanulaceae. It contains 32 genera, totalling about 1200 species. Some of the larger genera are '' Lobelia'', '' Siphocampylus'', ''Centropogon'', '' Burmeistera'' and '' Cyanea''. They are perennials, sometimes annuals, ranging in form from herbs to small trees. Most species are tropical in distribution, but in total this subfamily occurs almost worldwide, being absent only from Arctic regions, central Asia and the Near East. The subfamily is particularly diverse in Hawaii, where well over 100 species of Hawaiian lobelioids have radiated from a single introduction. This subfamily was formerly given family rank as Lobeliaceae, under a somewhat different circumscription. The leaves are simple and alternate. The plants have milky sap. The flowers are bilaterally symmetric with five lobes and stamen The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stam ...

Cyanea (plant)
''Cyanea'' is a genus of flowering plants in the family Campanulaceae. The name ''Cyanea'' in Hawaiian is ''hāhā''. These Hawaiian lobelioids are endemic to Hawaii with over 90% of ''Cyanea'' species are found only on one island in the Hawaiian chain.Givnish, T. J., et al. (2009)Origin, adaptive radiation and diversification of the Hawaiian lobeliads (Asterales: Campanulaceae).''Proceedings of the Royal Society B: Biological Sciences'' 276(1656), 407-16.

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree. History The theoretical f ...

Manduca Blackburni
''Manduca blackburni'', the Hawaiian tomato hornworm, Hawaiian tobacco hornworm or Blackburn's sphinx moth, is a moth in the family Sphingidae. The species was first described by Arthur Gardiner Butler in 1880. It is endemic to Hawaii. Previously known from all of the main islands, this rare moth is now limited to Maui, the Big Island, and Kahoolawe. It is found in coastal mesic and dry forests at elevations from sea level to . ''Manduca blackburni'' is closely related to the tomato hornworm (''M. quinquemaculata''), which it also physically resembles. It was listed as an endangered species by the United States Fish and Wildlife Service in 2000, making it the first Hawaiian insect to receive such a status. Larvae feed on plants in the nightshade family, Solanaceae, especially native ''aiea'' (''Nothocestrum'' spp.), but also non-native tomatoes (''Solanum lycopersicum''), tobacco (''Nicotiana tabacum''), tree tobacco (''N. glauca''), jimson weed (''Datura stramonium''), an ...

Sphingidae
The Sphingidae are a family of moths (Lepidoptera) called sphinx moths, also colloquially known as hawk moths, with many of their caterpillars known as “hornworms”; it includes about 1,450 species. It is best represented in the tropics, but species are found in every region.Scoble, Malcolm J. (1995): ''The Lepidoptera: Form, Function and Diversity'' (2nd edition). Oxford University Press & Natural History Museum London. They are moderate to large in size and are distinguished among moths for their agile and sustained flying ability, similar enough to that of hummingbirds as to be reliably mistaken for them. Their narrow wings and streamlined abdomens are adaptations for rapid flight. The family was named by French zoologist Pierre André Latreille in 1802. Some hawk moths, such as the hummingbird hawk-moth or the white-lined sphinx, hover in midair while they feed on nectar from flowers, so are sometimes mistaken for hummingbirds. This hovering capability is only known to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollination
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. Pollinating agents can be animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid offspring in nature and in plant breeding work. In angiosperms, after the pollen grain (gametophyte) has landed on the stigma, it germinates and develops a pollen tube which grows down the style until it reaches an ovary. Its two gametes travel down the tube to where the gametophyte(s) containing the female gametes are held within the carpel. After entering an ovum cell through the micropyle, one male nucleus fuses with the polar bodies to produce the endosperm tissues, while the other fuses with the ovule to produce the embryo. ...

Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are posi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Succulent
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulent plants may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%, such as ''Glottiphyllum semicyllindricum'' and ''Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in alpine ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, which makes them equipped to su ...
