An early taxonomic system, the de Candolle system was originally published in :
- A. P. de Candolle (2nd edition, 1819). Théorie élémentaire de la botanique, ou exposition des principes de la classification naturelle et de l’art de décrire et d’etudier les végétaux.
and followed up by the very extensive Prodromus:
- A. P. de Candolle et al. (1824–1873). Prodromus systemati naturalis regni vegetabilis sive enumeratio contracta ordinum, generum specierumque plantarum huc usque cognitarum, juxta methodi naturalis normas digesta. (available online at Gallica)
The system recognises the following groups of vascular plants:
- classis I. DICOTYLEDONEÆ
- subclassis 1. THALAMIFLORÆ
- subclassis 2. CALYCIFLORÆ
- subclassis 3. COROLLIFLORÆ
- subclassis 4. MONOCHLAMYDEÆ
- classis II. MONOCOTYLEDONEÆ
Famous quotes containing the word system:
“Our system is the height of absurdity, since we treat the culprit both as a child, so as to have the right to punish him, and as an adult, in order to deny him consolation.”
—Claude Lévi-Strauss (b. 1908)
