To J. D. Hooker [26 February or 4 March 1860]1
My dear Hooker
I forgot in this morning’s note to say that I have tried in vain to get any Goodenia from large nursery here.— If you have any plant which you can perfectly spare & would send it as by enclosed address.— But it does not of course really at all signify; as it half mere amusement— —2
Do get some of your men (is Mr Oliver to whom you alluded one of them?)3 to cross with distinct individual 2 or 3 times in morning a bunch of flowers of some healthy Australian mimosa. perhaps also Eucalyptus I see in Lecoq’s work he speaks of sterility of the group under culture; it may possibly be from want of crossing; but not probably.4
Remind your man that the stigma may be ready after or before pollen of own flower is shed.—
Ever yours | C. Darwin
