August 1831, The Gentleman's magazine, Volume 101, page 100, in an article titled Mexican Antiquities:

1850, M. A. Burnett, Plantae utiliores: or illustrations of useful plants, employed in the arts and medicine, part 8:
There existed only one specimen of this sacred tree in all Mexico, at least to the knowledge of the Mexicans; […] In spite, however, of the firmest convictions of the indivisibility of this tree — the Manitas, as it is commonly called — it has been propagated by cuttings, some of which are at this moment thriving in some of the larger stoves of our modern collectors.
1972, Pedro Alonso O'Crouley, Seán Galvin, A description of the Kingdom of New Spain, page 24:
There is a most singular tree called the manitas (little hands) because each leaf is a flower that is almost the exact shape of a man's hand. There is another tree, called the xochinacaztli, which produces the flor de la oreja [ear flower, so called because it is very like a human ear.
