Species Rochea bicolor

For Daniel de la Roche (Delaroche) (1743–1813), Swiss botanist and physician. De la Roche studied in Geneva, Leiden and Edinburgh, where he stayed until 1771, then practised in Geneva until 1881. He moved to Paris in 1782 as physician to the Swiss guards and consulting physician to the Duke of Orleans. When the 1792 revolution broke out, he emigrated to London, then Lausanne, returning to Paris in 1798 where he worked in various hospitals and on vaccines for smallpox. He gave botanical help to Augustin Pyramus de Candolle (1778–1841), who named the genus Rochea after him in 1802. He died from typhus brought to Paris by Napoleon’s troops returning from Russia, as did his doctor son, François Etienne (1780–1813).
