Acmella Nana
''Acmella nana'' is a species of land snail discovered from Borneo, Malaysia, in 2015. It was described by Jaap J. Vermeulen of the JK Art and Science in Leiden, Thor-Seng Liew of the Institute for Tropical Biology and Conservation at the Universiti Malaysia Sabah, and Menno Schilthuizen of the Naturalis Biodiversity Center in Leiden. It was named ''nana'' (Latin for "dwarf") due to its minute size. Measuring only 0.7 millimeters in size, it is the smallest known land snail as of 2015. It surpasses the earlier record attributed to ''Angustopila dominikae'', which is 0.86 mm in size, described from China in September 2015. Etymology The genus name ''Acmella'' is derived from a Greek word ''akme'' meaning "(the highest) point, edge or peak of anything." The species name ''nana'' was derived from a Latin word ''nanus'' meaning "dwarf", and was chosen because of its small size. Description ''Acmella nana'' has a gastropod shell, shell, which is whitish in colour and has a shin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micromollusk
A micromollusk is a shelled mollusk which is extremely small, even at full adult size. The word is usually, but not exclusively, applied to marine mollusks, although in addition, numerous species of land snails and freshwater mollusks also reach adult size at very small dimensions. These tiny mollusks or their tiny shells are easy to overlook, as many of them are not very noticeable to the naked eye, and thus many people are not aware that they even exist. Nonetheless there are large numbers of families and vast numbers of mollusk species, in particular marine gastropods or sea snails, which are minute enough to be considered micromollusks. Considerable numbers of marine gastropod species are only about 5 or 6 mm in adult size; many others are only about 2 or 3 mm in adult size; and a few have adult shells which are as small as one millimeter or even smaller still. Despite their tiny size, many of the shells have a good deal of elaborate sculpture. A fair numbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acmella Striata
''Acmella'' is a genus of plants in the family Asteraceae, described as a genus in 1807. It is native to the Americas and has been introduced to Asia, Africa, the Pacific islands, and Australia. One familiar species is '' Acmella oleracea'', which has been widely cultivated for centuries. It is used for food and medicine, and as an insecticide and an ornamental plant. Its common use as an herbal remedy for toothache and oral infections earned it the nickname toothache plant. These are annual or perennial herbs with branching stems usually reaching 10 to 20 centimeters in length, growing prostrate or erect. The oppositely arranged leaves are smooth-edged or toothed, and usually have rough or soft hairs. The flower heads A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, compos ... are u ...

Acmella Subcancellata
''Acmella'' is a genus of plants in the family Asteraceae, described as a genus in 1807. It is native to the Americas and has been introduced to Asia, Africa, the Pacific islands, and Australia.

These are annual or perennial herbs with branching stems usually reaching 10 to 20 centimeters in length, growing prostrate or erect. The oppositely arranged leaves are smooth-edged or toothed, and usually have rough or soft hairs. The flower heads are usually solitary at the tips of the stem branches, or occasionally borne in inflorescences. There are several to many disc florets with bell-shaped throats and 4 or 5 triangular lobes, usually yellow, or sometimes orange. Some species lack ray florets, but ...
