 After a period spent studying and working in the Veitch orchid houses, he set off back to South America.Chesterton was given specific instructions to locate and bring back to England ""the much-talked-of and long-desired "scarlet Odontoglossum"" ("Miltoniopsis vexillaria") which several collectors, including David Bowman, had previously located but had been unable to send live samples back to England, with samples often arriving at Chelsea ""dead or in a dying condition"".Chesterton eventually located the plant in the northern Cordillera Occidental in Colombia.
