Transcriber’s Notes
Reading edition
Retained publication information from the printed edition: this eBook is public-domain in the country of publication.
Corrected a few palpable typographical errors.
Slightly relocated species images before descriptive text, and flower color after the descriptive text, where they had been dislocated because of page layout issues in the printed exemplar.
In the text versions only, text in italics is delimited by _underscores_.
