Lathyrus grandiflorus (do) = is in this country more or less sterile. It never sets pods unless the flowers are visited by humble-bees (and this happens only rarely happens ), or unless they are artificially fertilised: see my article in Gardeners' Chronicle, 1858 page 828.

Sarothamnus scoparius (do) extremely sterile when the flowers are not neither visited by bees, and nor are not disturbed by being beaten by the wind against the surrounding nets.

Melilotus officinalis (do) an unprotected plant visited by bees produced at least 30 times more seeds than a protected one. On this same latter plant many scores of racemes did not produce a single pod; several racemes produced each one or two pods; five produced three pods ; six produced four pods ; and one produced six pods. On the unprotected plant several racemes produced fifteen pods; nine produced between 16 and 22 pods, and one produced 30 pods.

Lotus corniculatus (Leguminosæ do), several covered-up plants did not produced only two empty pods, & not a single good seed. and
