Elizabeth Andrew Warren facts for kids

Elizabeth Andrew Warren (born April 28, 1786 – died May 5, 1864) was a famous botanist from Cornwall, England. She was especially good at studying seaweeds, also known as marine algae. Elizabeth spent most of her life collecting plants along the beautiful southern coast of Cornwall. Her big dream was to create a special collection, called a herbarium, of all the plants native to Cornwall. She even helped other plant collectors and sent many plant samples to William Jackson Hooker at Kew Gardens for his research.

Biography

Early Life and Passion for Plants

Elizabeth Warren was born in Truro, Cornwall, on April 28, 1786. She spent most of her adult life in a small village called Flushing. This village was close to the busy port of Falmouth.

At a time when women in Britain could not go to universities, Elizabeth taught herself botany. She spent her time collecting and preparing plant samples. She also wrote letters to other botanists and worked with science groups.

Exploring Cornish Plants

Elizabeth focused her plant-collecting trips along the southern coast of Cornwall. She especially loved exploring the area around the River Fal. She paid close attention to marine algae (seaweeds) and cryptogams. Cryptogams are plants like ferns, mosses, and fungi that do not produce seeds or flowers.

Contributions to Science Societies

Elizabeth Warren was a founding member of the Royal Cornwall Polytechnic Society (RCPS). She also worked closely with the Royal Horticultural Society of Cornwall (RCHS). In 1833, the RCHS started holding yearly contests for the best and rarest plant samples. Elizabeth won these competitions many times.

She was soon put in charge of collecting plants for a special RCHS project. This project aimed to create a collection of all the native plants of Cornwall. Elizabeth herself contributed a huge number of plants. She provided 73% of the nearly 470 samples!

In 1837, the RCHS gave her a silver medal for her hard work. They praised her for helping to promote the study of local plants. In 1844, she became an honorary member of the society.

Discovering New Species

Elizabeth discovered new plant species in Cornwall. One of these was Kallymenia dubyi, a type of seaweed. This plant had not been found in Britain before.

In 1842, she published her findings on Cornish cryptogamic plants in the RCPS Annual Report. Later, in 1849, she shared her discoveries of marine algae from near Falmouth.

Working with William Hooker

In 1834, Elizabeth began writing letters to William Hooker. He was a very important botanist at Kew Gardens. Their letters continued for 25 years. She once called herself his "pupil, unluckily placed." This suggests she wished she could have studied with him more closely.

Over the years, she sent him many plant samples from Cornwall. She also sent samples from other countries that arrived in Britain through Falmouth. Hooker mentioned her as "Miss Warren" in his 1841 book, Manual of the British Algae. He thanked her and 18 other collectors for their help.

In his book about British seaweeds, Phycologia Britannica, Hooker listed an algae named after her. It was called Schizosiphon Warreniae by botanist Robert Caspary. Today, this algae is known as Rivularia biasolettiana.

Educational Chart for Schools

In 1843, Elizabeth Warren created a large chart about botany for schools. It was titled A Botanical Chart for the Use of Schools. She dedicated this chart to William Hooker. Even though it received good reviews, it was not widely used.

Later Life and Legacy

Elizabeth also wrote to other botanists, like John Ralfs. They both shared an interest in cryptogams. Her work is mentioned in Frederick Hamilton Davey's 1909 book, Flora of Cornwall. This book is a key reference on the plants of Cornwall.

Elizabeth continued her plant-collecting trips even into her sixties. She passed away at her sister's house in Kea on May 5, 1864. Tributes to her were published in the RCPS's annual report for 1864. Another tribute appeared in an 1865 issue of the Journal for the Royal Institution of Cornwall.

Her valuable plant collections are now kept at the Royal Institution of Cornwall.
