Tacca
The genus ''Tacca'', which includes the batflowers and arrowroot, consists of flowering plants in the order Dioscoreales, native to tropical regions of South America, Africa, Australia, Southeast Asia, and various oceanic islands. In older texts, the genus was treated in its own family Taccaceae, but the 2003 APG II system incorporates it into the family Dioscoreaceae. The APG III and APG IV systems continue to include ''Tacca'' in Dioscoreaceae. Description Many ''Tacca'' species have nearly black flowers, with conspicuous involucral bracts and bracteoles like whiskers. Engbert Drenth hypothesized that species of this genus attracted "carrion and dung flies" for pollination and that the fleshy seam of the seed might be attractive to ants and hence that ants might aid in seed dispersal. Taxonomy Earlier classifications placed the genus within the monogeneric family Taccaceae, which in turn was the sole family in the order Taccales. Dahlgren recognised the similarities to t ...

Tacca Leontopetaloides
''Tacca leontopetaloides'' is a species of flowering plant in the yam family Dioscoreaceae. It is native to Island Southeast Asia but have been introduced as canoe plants throughout the Indo-Pacific tropics by Austronesian peoples during prehistoric times. They have become naturalized to tropical Africa, South Asia, northern Australia, and Oceania. Common names include Polynesian arrowroot, Fiji arrowroot, East Indies arrowroot, and pia. History of cultivation Polynesian arrowroot is an ancient Austronesian root crop closely related to yams. It is originally native to Island Southeast Asia. It was introduced throughout the entire range of the Austronesian expansion during prehistoric times (c. 5,000 BP), including Micronesia, Polynesia, and Madagascar. Polynesian arrowroot have been identified as among the cultivated crops in Lapita sites in Palau, dating back to 3,000 to 2,000 BP. It was also introduced to Sri Lanka, southern India, and possibly also Australia through tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tacca Chantrieri
''Tacca chantrieri'' is a species of flowering plant in the yam family Dioscoreaceae. It is commonly called the black bat flower. It was first described in 1901 by Édouard André. Description ''Tacca chantrieri'' is an unusual plant in that it has black flowers. These flowers are somewhat bat-shaped, are up to 12 inches across, and have long 'whiskers' that can grow up to 28 inches. There are ten species in the genus ''Tacca''.:517 One of these, '' T. integrifolia'', is commonly called the "white bat plant." ''T. integrifolia'' is similar to ''T. chantrieri'', but has white bracts which are veined purple. ''T. integrifolia'' is larger than ''T. chantrieri'', reaching up to four feet in height (almost twice the size of ''T. chantrieri'' at a height of 24"-36"). ''Tacca'' species have been thought to be pollinated by flies seeking decaying organic material. This hypothesis was tested for ''T. chantrieri'', but the populations studied were found to be essentially self-pollinat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tacca Integrifolia
''Tacca integrifolia'', the white batflower, is a species of flowering plant in the yam family, Dioscoreaceae, native to tropical and subtropical rainforests of Asia. It was first described by the English botanist John Bellenden Ker Gawler in 1812. Description ''Tacca integrifolia'' is a herb growing from a thick, cylindrical rhizome. The leaf blades are borne on long stems and are oblong-elliptical to oblong-lanceolate, some , with tapering bases and slender pointed tips. The flower scape is about long and is topped with a pair of involucral bracts, broad and erect, white with mauve venation. Among the individual nodding flowers, which are arranged in an umbel, are further long, filiform (thread-like) bracts. The perianth of each flower is tubular and purplish-black, long, with two whorls of three perianth lobes, the outer three narrowly oblong and the inner three broadly obovate. The fruits are fleshy berries some long, and the seeds, which have six longitudinal ridges, hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tacca Maculata
''Tacca maculata'' is a plant in the Dioscoreaceae family, native to Western Australia, the Northern Territory, Fiji and Samoa It was first described by Berthold Carl Seemann in 1866. Description ''Tacca maculata'' has few leaves on petioles up to 1.9 m long, and (usually greater than 1 m long). The leaf lamina start trisected but then become irregularly dissected. The scape of the inflorescence is up to 2 m long. There are three or four involucral bracts and they are lanceolate to ovate. There are 20 to 40 flowers on pedicels which are up to 5 cm long. The sepals and petals are similar, and green on the outside, maroon on the inside. The style is about 2 mm long and has three glandular patches at the base. The fruit is rounded and topped with a persistent perianth. Habitat ''T. maculata'' usually grows in well-drained lateritic soils.

Dioscoreales
The Dioscoreales are an order of monocotyledonous flowering plants in modern classification systems, such as the Angiosperm Phylogeny Group and the Angiosperm Phylogeny Web. Within the monocots Dioscoreales are grouped in the lilioid monocots where they are in a sister group relationship with the Pandanales. The Dioscoreales must contain the family Dioscoreaceae which includes the yam (''Dioscorea'') which is an important food source in many regions. Older systems tended to place all lilioid monocots with reticulate veined leaves (such as Smilacaceae and Stemonaceae together with Dioscoraceae) in Dioscoreales. As currently circumscribed by phylogenetic analysis using combined morphology and molecular methods, Dioscreales contains many reticulate veined vines in Dioscoraceae, it also includes the myco-heterotrophic Burmanniaceae and the autotrophic Nartheciaceae. The order consists of three families, 22 genera and about 850 species. Description Dioscoreales are vines or herb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
