Crowea
''Crowea'' is a genus of small evergreen shrubs in the family Rutaceae, sometimes known as waxflowers. There are three species and many subspecies and cultivars, all of which are popular as ornamentals because of their abundant, attractive flowers which often occur during autumn and winter. ''Crowea'' species are all endemic to Australia, where they occur in Victoria, New South Wales and Western Australia. Description Croweas are evergreen shrubs to about 1.5 m tall. The leaves are simple, glabrous and, as with other members of the Rutaceae, have oil glands and are aromatic. The flowers occur singly in the axils of the leaves, are pink and star-shaped have five petals, five sepals and ten stamens in two rings around the ovary. ''Crowea'' are closely related, and the flowers similar in appearance to those of other member of the family Rutaceae, especially ''Philotheca'', ''Eriostemon'' and ''Boronia''.

He was an alderman of Norwich and elected as mayor in 1774 and 1797 Crowe had an interest in botany and was noted for his collection of willow species.

Glabrousness
Glabrousness (from the Latin ''glaber'' meaning "bald", "hairless", "shaved", "smooth") is the technical term for a lack of hair, down, setae, trichomes or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabresce ...

Salix
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Linnean Society Of London
The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and taxonomy. It possesses several important biological specimen, manuscript and literature collections, and publishes academic journals and books on plant and animal biology. The society also awards a number of prestigious medals and prizes. A product of the 18th-century enlightenment, the Society is the oldest extant biological society in the world and is historically important as the venue for the first public presentation of the theory of evolution by natural selection on 1 July 1858. The patron of the society was Queen Elizabeth II. Honorary members include: King Charles III of Great Britain, Emeritus Emperor Akihito of Japan, King Carl XVI Gustaf of Sweden (both of latter have active interests in natural history), and the eminent naturalist and broadcaster Sir David Attenborough.

Boronia
''Boronia'' is a genus of about 160 species of flowering plants in the citrus family Rutaceae. Most are endemic to Australia with a few species in New Caledonia, which were previously placed in the genus ''Boronella''. They occur in all Australian states but the genus is under review and a number of species are yet to be described or have the description published. Boronias are similar to familiar plants in the genera ''Zieria'', ''Eriostemon'' and '' Correa'' but can be distinguished from them by the number of petals or stamens. Some species have a distinctive fragrance and are popular garden plants. Description Plants in the genus ''Boronia'' are nearly always shrubs although a very small number occur as herbs or as small trees. The leaves are usually arranged in opposite pairs and may be simple leaves or compound leaves with up to nineteen or more leaflets, in either a pinnate or bipinnate arrangement. The flowers are arranged in groups in the leaf axils or on the ends ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
