Nematolepis
''Nematolepis'' is a genus of seven species of plants in the family Rutaceae, all Endemism, endemic to Australia. They are shrubs or small trees with more or less flat leaves arranged alternately and flowers with five overlapping petals and ten stamens. Six species are found in eastern Australia and one in Western Australia. Description Plants in the genus ''Nematolepis'' are shrubs or small trees with their stems, leaves and sepals covered with shield-like scales. The leaves are simple and arranged alternately. The flowers are arranged singly or in Cyme (botany), cymes in leaf axils, and have five sepals, five partly overlapping petals and ten stamens, all free from each other in most species. The five Gynoecium#Carpels, carpels are free from each other, each with two ovules and the Stigma (botany), stigma is not differentiated from the Style (botany), style. The fruit usually has a single seed in each of the five Follicle (fruit), follicles. Taxonomy The genus ''Nematolepis'' w ...

Style (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and slen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Plant Census
The Australian Plant Census (APC) provides an online interface to currently accepted, published, scientific names of the vascular flora of Australia, as one of the output interfaces of the national government Integrated Biodiversity Information System (IBIS – an Oracle Co. relational database management system).

Nikolai Turczaninow
Nikolai Stepanovich Turczaninow ( ru , Николай Степанович Турчанинов, 1796 in Nikitovka, now in Krasnogvardeysky District, Belgorod Oblast, Russia – 1863 in Kharkov) was a Russian botanist and plant collector who first identified several genera, and many species, of plants. Education and career Born in 1796, Turczaninow attended high school in Kharkov. In 1814, he graduated from Kharkov University, before working as a civil servant for the Ministry of Finance in St. Petersburg. Soon after, in 1825, Turczaninow published his first botanical list. Despite being employed in a different field, he continued his largely self-taught botanical work. In 1828, he was assigned an administrative post in Irkutsk, Siberia. This allowed him to collect in the Lake Baikal area, which is known for its rich biodiversity. A spate of papers followed, and Turczaninow established his own herbarium containing plants from the region. In 1830, he was appointed a Fellow o ...

Follicle (fruit)
In botany, a follicle is a dry unilocular fruit formed from one carpel, containing two or more seeds. It is usually defined as dehiscing by a suture in order to release seeds, for example in ''Consolida'' (some of the larkspurs), peony and milkweed (''Asclepias''). Some difficult cases exist however, so that the term indehiscent follicle is sometimes used, for example with the genus ''Filipendula'', which has indehiscent fruits that could be considered intermediate between a (dehiscent) follicle and an (indehiscent) achene. An aggregate fruit that consists of follicles may be called a follicetum. Examples include hellebore, aconite, ''Delphinium'', ''Aquilegia'' or the family Crassulaceae, where several follicles occur in a whorl on a shortened receptacle, or ''Magnolia'', which has many follicles arranged in a spiral on an elongated receptacle. The follicles of some species dehisce by the ventral suture (as in ''Banksia''), or by the dorsal suture (as in ''Magnolia'').Kapil, R. ...
