Domingo Bello y Espinosa (31 July 1817, La Laguna, Canary Islands – 21 January 1884) was a Spanish lawyer and botanist.
Here he befriended Leopold Krug, a German consul stationed in Mayagüez, who like Bello y Espinosa, was an amateur botanist.
With Krug, he collected flora native to the island, and in the meantime, took copious notes of the various plants.
Bello y Espinosa's original plant collections from Puerto Rico were eventually destroyed by insects.
[1] In 1880 Bello y Espinosa published a book of prose, titled "Un Jardín Canario".
