Corms
A corm, bulbo-tuber, or bulbotuber is a short, vertical, swollen underground plant stem that serves as a storage organ that some plants use to survive winter or other adverse conditions such as summer drought and heat ( perennation). The word ''cormous'' usually means plants that grow from corms, parallel to the terms ''tuberous'' and ''bulbous'' to describe plants growing from tubers and bulbs. Structure A corm consists of one or more internodes with at least one growing point, generally with protective leaves modified into skins or tunics. The tunic of a corm forms from dead petiole sheaths—remnants of leaves produced in previous years. They act as a covering, protecting the corm from insects, digging animals, flooding, and water loss. The tunics of some species are thin, dry, and papery, at least in young plants, however, in some families, such as ''Iridaceae'', the tunic of a mature corm can be formidable protection. For example, some of the larger species of '' W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taro
Taro () (''Colocasia esculenta)'' is a root vegetable. It is the most widely cultivated species of several plants in the family Araceae that are used as vegetables for their corms, leaves, and petioles. Taro corms are a food staple in African, Oceanic, and South Asian cultures (similar to yams). Taro is believed to be one of the earliest cultivated plants. Names and etymology The English term '' taro'' was borrowed from the Māori language when Captain Cook first observed ''Colocasia'' plantations there in 1769. The form ''taro'' or ''talo'' is widespread among Polynesian languages:*''talo'': taro (''Colocasia esculenta'') – entry in the ''Polynesian Lexicon Project Online'' (Pollex). in Tahitian; ...

Colocasia Esculenta Dsc07801
''Colocasia'' is a genus of flowering plants in the family Araceae, native to southeastern Asia and the Indian subcontinent. Some species are widely cultivated and naturalized in other tropical and subtropical regions. The names elephant-ear and cocoyam are also used for some other large-leaved genera in the Araceae, notably ''Xanthosoma'' and ''Caladium''. The generic name is derived from the ancient Greek word ''kolokasion'', which in Greek, botanist Dioscorides (1st century AD) may have inferred the edible roots of both '' Colocasia esculenta'' and ''Nelumbo nucifera''. The species ''Colocasia esculenta'' is invasive in wetlands along the American Gulf coast, where it threatens to displace native wetland plants. Description They are herbaceous perennial plants with a large corm on or just below the ground surface. The leaves are large to very large, long, with a sagittate shape. The elephant's-ear plant gets its name from the leaves, which are shaped like a large ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alismataceae
The water-plantains (Alismataceae) are a family of flowering plants, comprising 19 genera (17 extant and 2 fossil) and 117 species. The family has a cosmopolitan distribution, with the greatest number of species in temperate regions of the Northern Hemisphere. Most of the species are herbaceous aquatic plants growing in marshes and ponds. Description Most Alismataceae are robust perennials, but some may be annual or perennial, depending on water conditions — they are normally perennial in permanent waters, annual in more seasonal conditions but there are exceptions. The stems are corm-like or stoloniferous. Juvenile and submerse leaves are often linear, whilst more mature and emerse leaves can be linear to ovate or even sagittate. Most have a distinct petiole, with a sheathed base. The inflorescence is usually compound with whorls of branches, though some are umbel-like, and others have solitary flowers. The flowers are regular, bisexual or unisexual. There are three sep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alocasia Macrorrhizos Corm (Philippines) 01
''Alocasia'' is a genus of rhizomatous or tuberous, broad-leaved, perennial, flowering plants from the family Araceae. There are about 90 accepted species native to tropical and subtropical Asia and eastern Australia. Around the world, many growers widely cultivate a range of hybrids and cultivars as ornamentals. Description The large, cordate or sagittate leaves grow to a length of on long petioles. Their araceous flowers grow at the end of a short stalk, but are not conspicuous; often hidden behind the leaf petioles. The corms of some species can be processed to make them edible, however, the raw plants contain raphid or raphide crystals of calcium oxalate along with other irritants (possibly including proteases) that can numb and swell the tongue and pharynx. This can cause difficulty breathing and sharp pain in the throat. Lower parts of the plant contain the highest concentrations of the poison. Prolonged boiling before serving or processing may reduce risk of adver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a Plant stem, stem that is composed of a main branch or a complicated arrangement of branches. Morphology (biology), Morphologically, it is the modified part of the shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a Peduncle (botany), peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a Pedicel (botany) , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of '' Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The group is widespread across Africa, the Mediterranean, and central and southwestern Asia. The genus name is a tribute to the English botanist Robert More. Moraeas have iris-like flowers.
