In the past few decades several different species of the genus Oxalis have been recorded as new to Belgium. Horticultural activities play an important role in the introduction and local dispersal of both cultivated species (as garden escapes) and weeds. A key for the identification of twelve species is followed by brief comments. Particular attention is drawn to gaps in the present state of our knowledge: distribution and status in Belgium, morphological variation within certain species, and identification problems.}, url = {http://www.br.fgov.be/DUMORTIERA/DUM_101/Dum\%20101_9-22_Oxalis_Hoste.pdf}, author = {Ivan Hoste} } @article {dum4632, title = {A revision of Bromus section Ceratochloa (Pooideae, Poaceae) in Belgium.}, journal = {Dumortiera}, volume = {101}, year = {2012}, month = {10/2012}, pages = {30-45}, chapter = {30}, author = {Filip Verloove} } @article {dum4452, title = {Drie slecht gekende taxa van het genus Calystegia(Convolvulaceae) in Belgi{\"e}}, journal = {Dumortiera}, volume = {100}, year = {2012}, month = {04/2012}, pages = {25-29}, chapter = {25}, abstract = {Three little-known taxa of the genus Calystegia (Convolvulaceae) in Belgium. Recent fieldwork and a thorough herbarium revision have resolved some taxonomic problems within the genus Calystegia in Belgium. The enigmatic and non-native Calystegia silvatica is reliably reported for the first time. It is probably often overlooked and seems well-naturalised locally. Several additional records (including a recent one) are provided for non-native Calystegia pulchra. Finally, we ascribe pink- flowered forms of native Calystegia sepium to subsp. sepium f. colorata.
