Fresh matter production by two forms of Oxalis latifolia as influenced by soil and climate

Oxalis latifolia is a widely distributed weed that mainly affects corn fields, orchards, plant nurseries and gardens. Two forms of the weed have been identified: the common form, with fish-tailed leaflets, bulbils growing on stolons and dark pink flowers, and the Cornwall form, with rounder leaflets...
