Abstract
DURING the past summer I have found the following species in a gyno-diœcious condition, namely, Ranunculus acris, R. repens, R. bulbosus, and Stachys germanica, all of which have the corolla considerably reduced in size, and the stamens in R. acris and S. germanica either absent or reduced to scale-like bodies devoid of pollen. In R. repens and R. bulbosus the stamens are not so much reduced, but so far as I can judge they produced little or no pollen. The female form in R. acris is very common in Lancashire, but I failed to find any on the Lincolnshire coast although I searched carefully for it. In R. repens the female form is very rare, having seen only about thirty plants in all. I have also found the Geum rivale to be andro-monœcious. So far as I can ascertain these plants have not been noticed in the state described above.
