David Douglas (botanist)
David Douglas (25 June 1799 – 12 July 1834) was a Scottish botanist, best known as the namesake of the Douglas fir. He worked as a gardener, and explored the Scottish Highlands, North America, and Hawaii, where he died. Early life Douglas was born in Scone, Perthshire, the second son of John Douglas, a stonemason, and Jean Drummond. He attended Kinnoull School and upon leaving found work as an apprentice to William Beattie, head gardener at Scone Palace, the seat of the Earl of Mansfield. He spent seven years in this position, completing his apprenticeship, and then spent a winter at a college in Perth to learn more of the scientific and mathematical aspects of plant culture. After a further spell of working at Valleyfield House in Fife (during which time he had access to a library of botanical and zoological books) he moved to the Botanical Gardens of Glasgow University and attended botany lectures. William Jackson Hooker, who was Garden Director and Professor of Bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ...

Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...
