New xenophytes from la Palma (Canary Islands, Spain), with emphasis on naturalized and (potentially) invasive species-Part 2

Abstract

Several months of feld work in La Palma (western Canary Islands) yielded a number of interesting new records of non-native vascular plants. Abutilon theophrasti, Agrostis ×fouilladeana, Alternanthera brasiliana, Bupleurum salicifolium subsp. salicifolium, Callisia fragrans, Emilia coccinea, Hyparrhenia sinaica, Ipomoea purpurea, Jasminum polyanthum, Macfadyena unguis-cati, Malvastrum coromandelianum subsp. coromandelianum, Misopates calycinum, Nephrolepis cordifolia, Opuntia microdasys, Passiflora subpeltata, Plantago lanceolata, Polygonum aviculare subsp. rurivagum, Pseudogynoxys chenopodioides, Psidium littorale, Robinia pseudoacacia, Rosa micrantha, Rumex bucephalophorus subsp. gallicus, Sorghum bicolor subsp. verticilliflorum, Sphagneticola trilobata, Syzygium jambos, Thunbergia alata and Youngia japonica subsp. japonica are naturalized or (potentially) invasive xenophytes, reported for the frst time from either the Canary Islands or La Palma. Fourteen additional, presumably ephemeral taxa are reported for the frst time from the Canary Islands, whereas 15 ephemeral taxa are new for La Palma.
