Swartz has well observed that this is distinguished from Oncidium 
tetrapetalum by its broader serrulated leaves, and its acuminate not - 
tuse sepals. For fine specimens gathered in Saint Domingo I am indebte 
to Charles Mackenzie, Esq. 
Like many other species it varies remarkably in stature; the spec" 
rye in the Banksian Herbarium from Swartz are not half the size 
of mine.
