- Comments
- For this exotic spurge so far there is one voucher in the Watershed: Rio Grande Co, in a fallow field near Monte Vista (1992). Apparently this record is rejected by BONAP (2022). So the photorecord of a plant by a road in Conejos Co near Mogotes Cpgd (2015, 2021) would add Conejos to counties in BONAP (Ackerfield 2022 has no distribution map for the species). More observation might be expected in the Watershed. Cypress spurge has spread throughout the USA except for the southern third, and in six years BONAP has added 10 Colorado counties to the 3 shown in Ackerfield 2015. It is not yet recorded from New Mexico or Texas, so the Conejos observation is the only one for the entire Rio Grande drainage. It is on Colorado's A list of "noxious weeds."
