Bulbotuber
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 '' Wats ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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; in < ...

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 plant, herbaceous aquatic plants growing in marshes and ponds. Description Most Alismataceae are robust Perennial plant, perennials, but some may be Annual plant, annual or perennial, depending on water conditions — they are normally perennial in permanent waters, annual in more seasonal conditions but there are exceptions. The Plant stem, stems are corm-like or stoloniferous. Juvenile and submerse Leaf, leaves are often Leaf shape, linear, whilst more mature and emerse leaves can be linear to Leaf shape, ovate or even Leaf shape, sagittate.

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 stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the 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. 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. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Homeria
''Moraea'', the Cape tulips, is a genus of plants in the family Iridaceae, first described as a genus in 1758. 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. The corms of some species have been used as food, however they are usually small and some species are unpleasant, and some are poisonous. Some ''Moraea'' species are: * ''Moraea albiflora'' G. J.

Pocket Gopher
Pocket gophers, commonly referred to simply as gophers, are burrowing rodents of the family Geomyidae. The roughly 41 speciesSearch results for "Geomyidae" on thASM Mammal Diversity Database are all endemic to North and Central America. They are commonly known for their extensive tunneling activities and their ability to destroy farms and gardens. The name "pocket gopher" on its own may refer to any of a number of genera within the family Geomyidae. These are the "true" gophers, but several ground squirrels in the distantly related family Sciuridae are often called "gophers", as well. The origin of the word "gopher" is uncertain; the French ''gaufre'', meaning waffle, has been suggested, on account of the gopher tunnels resembling the honeycomb-like pattern of holes in a waffle; another suggestion is that the word is of Muskogean origin. Description Gophers weigh around , and are about in body length, with a tail long. A few species reach weights approaching . Within any sp ...

Blesmol
The blesmols, also known as mole-rats, or African mole-rats, are burrowing rodents of the family Bathyergidae. They represent a distinct evolution of a subterranean life among rodents much like the pocket gophers of North America, the tuco-tucos in South America, or the Spalacidae from Eurasia. Distribution Modern blesmols are found strictly in sub-Saharan Africa. Fossil forms are also restricted almost exclusively to Africa, although a few specimens of the Pleistocene species ''Cryptomys asiaticus'' have been found in Israel. Nowak (1999) also reports that †''Gypsorhychus'' has been found in fossil deposits of Mongolia. Anatomy Blesmols are somewhat mole-like animals with cylindrical bodies and short limbs. They range from in length, and from in weight, depending on the species. Blesmols, like many other fossorial mammals, have greatly reduced eyes and ear pinnae, a relatively short tail, loose skin, and (aside from the hairless naked mole rat) velvety fur. Blesmols ...
