Corms
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. 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 '' Watsonia'' acc ... [...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, stems and Petiole (botany), petioles. Taro corms are a food staple in Culture of Africa, African, Oceania, Oceanic, East Asian, Southeast Asian and South Asian cultures (similar to Yam (vegetable), yams). Taro is believed to be one of the earliest cultivated plants. Common names The English term '':wikt:taro#English, taro'' was :wikt:taro#Maori, borrowed from the Māori language when James Cook, Captain Cook first observed ''Colocasia'' plantations in New Zealand in 1769. The form ''taro'' or ''talo'' is widespread among Polynesian languages:*''talo'': taro (''Colocasia esculenta'') – entry in the ''Polynesian Lexicon Project ...

Colocasia Esculenta Dsc07801
''Colocasia'' is a genus of flowering plants in the family Araceae, native to Southeast 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 , which in the Koine Greek of the 1st century botanist Pedanius Dioscorides may have meant the edible roots of both taro (''C. esculenta'') and ''Nelumbo nucifera''. The species ''Colocasia esculenta'' is invasive in wetlands along the Gulf Coast of the United States, 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 la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lapeirousia
''Lapeirousia'' is a genus in the plant family Iridaceae. It is endemic to sub-Saharan Africa, about a third of the species occurring in fynbos. Origin of genus name The genus ''Lapeirousia'' was described by Pierre André Pourret in Mém. Acad. Sci. Toulouse 3 : 79 (1788); Bak. In FC. 6 : 88 (1896) in part; Goldblatt in Contrib. Bol. Herb. 4 : 1 (1972); Sölch & Roessl. in FSWA. 155 : 6 (1969). Chasmatocallis Foster in Contrib. Gray Herb. 127 : 40 (1939).Dyer, R. Allen, “The Genera of Southern African Flowering Plants”. , 1975 He named the genus in honour of his friend, the botanist Philippe-Isidore Picot de Lapeyrouse. The inconsistent spellings of that name no doubt led to the original genus name being spelt "Lapeirousia" and contributed to various subsequent misspellings of the genus in various reference sources, notably "Lapeyrousia".Chittenden, Fred J.

Tunica (biology)
In biology, a tunica (, ; : tunicae) is a layer, coat, sheath, or similar covering. The word came to English from the Neo-Latin of science and medicine. Its literal sense is about the same as that of the word ''tunic'', with which it is cognate. In biology, one of its senses used to be the taxonomic name of a genus of plants, but the nomenclature has been revised and those plants are now included in the genus '' Petrorhagia''. In modern biology in general, ''tunica'' occurs as a technical or anatomical term mainly in botany and zoology. It usually refers to membranous structures that line or cover particular organs. In many such contexts, ''tunica'' is used interchangeably with ''tunic'' according to preference. An organ or organism that has a tunic(a) may be said to be ''tunicate'', as in a ''tunicate bulb''. This adjective ''tunicate'' is not to be confused with the noun ''tunicate'', which refers to a member of the subphylum '' Tunicata''. Botanical and related usages In botany ...

Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), 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. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bract
In botany, a bract is a modified or specialized leaf, associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves in size, color, shape or texture. 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 or ebracteolate. Variants Some bracts are brightly coloured which aid in the attraction of 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 palea (upper bract), while each spikelet (group of florets) has a further pair o ...
