Erythranthe guttata

Erythranthe guttata (DC.) G.L. Nesom (syn.: Mimulus guttatus DC.) (N-Am.) – A rare but much increasing, locally naturalized or locally invasive escape from cultivation. Apparently first documented from Biourge (Bertrix) where it was found since 1953 and repeatedly confirmed afterwards (see also van Rompaey & Delvosalle 1978). Subsequently also seen in Martilly in 1971 and since 1985 in Bouillon. However, by far most records are fairly recent. In an increasing number of localities it is known since quite a long time now and obviously naturalized. This holds true, for instance, for Parc de Woluwé (Brussels, at least since 1994; Saintenoy-Simon 1998) and several different riverlet valleys in Wallonia: riverlet Ywoigne (Saintenoy-Simon 2008), riverlet Haute-Vierre near Saint-Médard (with historical as well as recent records). Most other Walloon records seem recent. In Flanders perhaps slightly rarer but also increasing, especially in some river valleys (Leie, Maas, Schelde; see Verloove 2002, Verloove 2006).

Erythranthe guttata usually grows by ponds and rivers, in marshland and other damp places. For quite a long time it was considered non-invasive but at least in some places it produces lots of viable seed and seems to be a treat for native waterside vegetation. Additional information on its invasive behaviour in Belgium is available here: http://ias.biodiversity.be/species/show/116. Information for the whole of Europe was gathered by Tokarska-Guzik & Dajdok (2010).

Most populations seen so far seem to correspond with genuine Erythranthe guttata: 100% fertile plants with corollas with unspotted lobes and more or less closed throat. However, at least one hybrid has been reliably recorded in Belgium, Mimulus xrobertsii Silverside (Erythranthe guttata x lutea). It is a common and widely dispersed plant in the British Isles (Silverside 1990, Stace 2010) and possibly overlooked in Belgium. It is more or less intermediate between both parents. It was recorded in 1991 as an escape in the Wespelaar arboretum in Haacht.
