Harveya

Harveya is a genus of parasitic plants in the family Orobanchaceae. The approximately 29 species included are native to Africa from Eritrea to South Africa, Madagascar and the Mascarene Islands, the Arabian Peninsula, and Turkmenistan in Central Asia. In South Africa they are commonly known as 'inkblom', because early settlers used the flowers to make ink, and this is the source of the English common-names for the genus of ink flower or ink plant. The genus was named after William Henry Harvey, thus achieving one of his childhood ambitions. Discussing his vocational prospects as a youth, Harvey wrote that he was "neither fit to be a doctor nor a lawyer, lacking courage for the one, and face for the other, and application for both.... All I have a taste for is natural history, and that might possibly lead in days to come to a genus called Harveya, and the letters F.L.S. after my name, and with that I shall be content."...read more on Wikipedia.
