This lovely little thing was dedicated to the promoter of our 
present work in these terms :—‘ ‘Thus we have regarded it our 
duty to act as an interpreter both of the thankful and confidential 
feelings of Plewrothalloids, and of our own, by making W. W. 
Saunders, Esq., the godfather of a lovely young anonymous 
Plewrothallis, coming, we believe (papers not seen) out of Mr. 
Low’s Nursery, into which it was introduced froin Brazil.” Alas! 
the “papers not seen” would appear to have been written in a 
prophetical spirit. When (in October, 1857) at Reigate, I was 
informed that the indication Brazilian was not correct, but that 
the grand book of Saundersian Orchids (kept with perfect 
accuracy) indicated a Lindenian origin, and W. Wilson Saunders, 
Esq., suggested that the plant might come from Popayan.
