Core NG members might have realised I'm not contributing as often as before. The reason is simple: the field season for my aquatic plant project has started, and I'm emersing myself (literally) in the collecting, identification, and photo documentation of all the species on my "to-do" list for 2020.
Some species need to be cultivated as part of the identification process. This applies to most of the various duckweeds. Thus I extend my (limited) skills as an aquatic gardener these days

Here are 6 culture jars with collections for last days. There are about 4 species of duckweed involved in them.
