Streptoglossa Steetzii
''Streptoglossa'' is a genus of flowering plants in the family Asteraceae and is endemic to Australia. Plants in the genus ''Streptoglossa'' are aromatic herbs or shrubs with simple leaves, composite flowerheads with 15 to more than 100 fertile florets, the outer florets female and the disc florets bisexual. Description Plants in the genus ''Streptoglossa'' are shrubs, or annual or perennial herbs, often aromatic, with simple, often glandular leaves. The daisy-like flowers are pink to purple and have 15 to 100 or more fertile florets, the outer florets female with a lobed ligule, and the disc florets bisexual and tube-shaped. There are 3 to 6 rows of overlapping involucral bracts at the base of the heads. The fruit is a hairy achene, the pappus with many barbed or feathery bristles. Taxonomy The genus ''Streptoglossa'' was first formally described by Joachim Steetz, but published in 1863 by Ferdinand von Mueller in the ''Edinburgh New Philosophical Journal''. Mueller used th ...

Pappus (botany)
In Asteraceae, the pappus is the modified calyx, the part of an individual floret, that surrounds the base of the corolla tube in flower. It functions as a wind-dispersal mechanism for the seeds. The term is sometimes used for similar structures in other plant families e.g. in certain genera of the Apocynaceae, although the pappus in Apocynaceae is not derived from the calyx of the flower. In Asteraceae, the pappus may be composed of bristles (sometimes feathery), awns, scales, or may be absent, and in some species, is too small to see without magnification. In genera such as ''Taraxacum'' or ''Eupatorium'', feathery bristles of the pappus function as a "parachute" which enables the seed to be carried by the wind. The name derives from the Ancient Greek word ''pappos'', Latin ''pappus'', meaning "old man", so used for a plant (assumed to be an ''Erigeron'' species) having bristles and also for the woolly, hairy seed of certain plants. The pappus of the dandelion plays a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteraceae Genera
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technically ...
