Chatham Island, Watson. I have no native specimens, the above description being 
drawn up from cultivated ones. 
I find amongst Sinclair’s plants, without habitat, a small scrap of a Cynoglossum, from the 
neighbourhood of Auckland. The geuus may be known from Myosotis by the nuts covered 
with barbed bristles; the species looks like the common tropical C. micranthum, and is 
probably an introduced weed.
