author
b. 1876
Known for practical books on weeds and poisonous plants, this British botanist wrote for readers who needed clear, useful guidance in the field as much as in the library. His surviving works suggest a specialist focused on agriculture, plant identification, and the everyday problems plants could cause.

by Harold Cecil Long
Harold Cecil Long was a British botanist and writer born in 1876. Catalog records and reference databases identify him as the author of botanical works published under the names Harold Cecil Long and H. C. Long.
He is best known for books including Plants Poisonous to Live Stock and, with John Percival, Common Weeds of the Farm & Garden. These works point to a practical interest in economic botany: helping farmers, gardeners, and agricultural readers recognize troublesome or dangerous plants.
Reliable biographical detail about his personal life appears to be scarce in the sources readily available online, so this profile focuses on what can be confirmed from library and public-domain records: he wrote clear, applied botanical books that continued to circulate well beyond their original publication period.
