Taste of Bryophyllum: A Trip Down
Problem: In 1813 Benjamin
Heyne wrote the following letter to the Linnean Society.
I had an opportunity some time ago of mentioning to you a remarkable deoxidation of the leaves of a plant in day-light. As the circumstance is in itself curious, and throws great light on the opinion of those celebrated philosophers who have written on the subject, I will state it shortly in this letter, which if you please, you may in extract, or in any way you think proper, lay before the Society. The leaves of the Cotyledon calycina, the plant called by Mr. Salisbury Bryophyllum calycinum, which on the whole have an herbaceous taste, are in the morning as acid as sorrel, if not more so. As the day advances, they lose their acidity, and are tasteless about noon; and become almost bitterish towards evening. This is the case in India, where this plant is pretty generally cultivated in our gardens and it remains to be seen if the same takes place in the hot-houses in England, where it has been lately introduced.
