When Swartz described Epidendrum trigoniflorum, he 
based his description on his own collection from Jamaica. He 
also prepared detailed drawings of it for inclusion in his Icones 
Plantarum Incognitarum, t. 49, but they remained unpublished. 
Under Epidendrum trigoniflorum Swartz cited in synonymy 
the plate of Epidendrum ophioglossoides, t. 133, f. 2, which 
Jacquin published in 1763. In 1791, in his Observationes 
Botanicae, p. 332, under E. ophioglossoides Swartz remarks: 
**Plantae Plumieri & Jacquini certe distinctae. ... JAC- 
QUINI... ad E. trigoniflorum (Prodr. p. 125) pertinet, affir- 
mante planta Ipsius in Museo BANKSIANO servata.”’ I have 
examined the Jacquin material and it is specifically different 
from Epidendrum trigoniflorum, while the Plumier material is a 
true Pleurothallis. 
Although convinced that the Plumier and Jacquin illus- 
trations and material were different from one another, in 1800, 
in proposing the genus Sre/is, Swartz united them under Stelis 
ophioglossoides under which name the error persisted until 
recently (See Garay & Sweet in Journ. Arnold Arb. 53: 391 and 
528, 1972). I have recently noticed that Turton has already 
separated Epidendrum ophioglossoides Jacq. and Epidendrum 
trigoniflorum Sw. as two distinct species in his Vegetable 
Kingdom 2: 1508 and IS5I1, 1806.
