Hemiandra
''Hemiandra'' is a genus of nine species of flowering plants of the family Lamiaceae and is endemic to Western Australia. Plants in the genus ''Hemiandra'' are shrubs with sessile leaves arranged in opposite pairs, petals with five lobes arranged in two "lips" and the fruit a capsule usually containing four nuts. Description Plants in the genus ''Hemiandra'' are prostrate to medium shrubs with rigid, leathery, sessile leaves arranged in opposite pairs. The flowers have five egg-shaped sepals fused at the base and five petals fused at the base to form a corolla with two "lips". The upper lip short of the corolla is erect with two lobes, the lower lip longer, spreading and three-lobed. The middle lobe itself often has two lobes. The flowers are white, pink or purple, often spotted in the throat. There are four stamens and a single style with two stigmas. The fruit is a capsule usually containing four nuts.

Hemiandra Pungens
''Hemiandra pungens'', commonly known as snakebush, is a shrub or trailing plant that is endemic to southwestern Western Australia. Description Ranging in height from 5 cm to 100 cm, it occurs on rock outcrops. It is a variable species that may form a trailing plant or a small shrub. The spotted flowers may be white, pink or bluish-purple and appear throughout the year. It flowers in the spring. Taxonomy The species was formally described in 1810 by Scottish botanist Robert Brown. A widely cultivated variety lacking hairs on the stems and leaves is sometimes classified as a variety (''Hemiandra pungens'' var. ''glabra''), or by some authors as ''Hemiandra glabra'', or treated as a synonym A synonym is a word, morpheme, or phrase that means exactly or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language, the words ''begin'', ''start'', ''commence'', and ''initiate'' are al ... of ''Hemiandra pungens''. C ...

Hemiandra Gardneri
''Hemiandra gardneri'', commonly known as red snakebush, is a flowering plant in the family Lamiaceae and is endemic to Western Australia. It is a prostrate, trailing plant with greyish foliage and mostly red flowers. Description ''Hemiandra gardneri'' is a prostrate, perennial mat forming shrub growing up to high, wide and stems put long. The leaves are linear to linear oblong-lance shaped, green or greyish, up to long and wide, covered in short hairs and pointed at the apex. The red to dark pink flowers are borne usually in clusters near the end of stems. The fused corolla (botany), corolla tube petals about long, 2 lipped, three lower lobes, 2 upper lobes and anthers protruding a short distance from the corolla. The calyx (botany), calyx is bell-shaped, hairy, long and two lipped. Flowering occurs from August to October. Taxonomy and naming ''Hemiandra gardneri'' was first formally described in 1927 by Oswald Hewlett Sargent and the description was published in ''Jo ...

Hemiandra Linearis
''Hemiandra linearis'', commonly known as speckled snakebush, is a species of prostrate to ascending shrub that is endemic to the south-west of Western Australia. Description ''Hemiandra linearis'' is a prostrate to ascending shrub that typically grows to a height of up to . It has leaves long and wide arranged in opposite pairs. The are four sepals joined at the base with lobes long. The petals are long and white, cream-coloured, purple, lilac or violet with dots or stripes near the base. Flowering occurs from October to November or December. Taxonomy ''Hemiandra linearis'' was formally described in 1837 by George Bentham in Stephan Endlicher's ''Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel'' from material collected near the Swan River by Charles von Hügel.

Lamiaceae Genera
The Lamiaceae ( ) or Labiatae are a family of flowering plants commonly known as the mint, deadnettle or sage family. Many of the plants are aromatic in all parts and include widely used culinary herbs like basil, mint, rosemary, sage, savory, marjoram, oregano, hyssop, thyme, lavender, and perilla, as well as other medicinal herbs such as catnip, salvia, bee balm, wild dagga, and oriental motherwort. Some species are shrubs, trees (such as teak), or, rarely, vines. Many members of the family are widely cultivated, not only for their aromatic qualities, but also their ease of cultivation, since they are readily propagated by stem cuttings. Besides those grown for their edible leaves, some are grown for decorative foliage. Others are grown for seed, such as '' Salvia hispanica'' (chia), or for their edible tubers, such as '' Plectranthus edulis'', '' Plectranthus esculentus'', ''Plectranthus rotundifolius'', and ''Stachys affinis'' (Chinese artichoke).

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains '' microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
