PART 3.— Several months of field work in La Palma (western Canary Islands) yielded a number of interesting new records of non-native vascular plants. Alstroemeria aurea, A. ligtu, Anacyclus radiatus subsp. radiatus, Chenopodium album subsp. borbasii, Cotyledon orbiculata, Cucurbita ficifolia, Cynodon nlemfuensis, Datura stramonium subsp. tatula, Digitaria ciliaris var. rhachiseta, D. ischaemum, Diplotaxis tenuifolia, Egeria densa, Eugenia uniflora, Galinsoga quadri- radiata, Glebionis segetum, Kalanchoe laetivirens, Lemna minuta, Ligustrum lucidum, Lotus broussonetii, Oenothera fal- lax, Paspalum notatum, Passiflora caerulea, P. manicata × tarminiana, P. tarminiana, Pelargonium capitatum, Phaseolus lunatus, Portulaca trituberculata, Pyracantha angustifolia, Sedum mexicanum, Trifolium lappaceum, Urochloa mutica, U. subquadripara and Volutaria tubuliflora are naturalized or (potentially) invasive xenophytes or of special floristic in- terest, reported for the first time from either theCanary Islands or La Palma. Three additional, presumably ephemeral taxa are reported for the first time from the Canary Islands, whereas seven ephemeral taxa are new for La Palma.
