LETTER 592. TO J.D. HOOKER. November 3rd [1862].
Do you remember the scarlet Leschenaultia formosa with the sticky margin outside the indusium? Well, this is the stigma--at least, I find the pollen-tubes here penetrate and nowhere else. What a joke it would be if the stigma is always exterior, and this by far the greatest difficulty in my crossing notions should turn out a case eminently requiring insect aid, and consequently almost inevitably ensuring crossing. By the way, have you any other Goodeniaceae which you could lend me, besides Leschenaultia and Scaevola, of which I have seen enough?
I had a long letter the other day from Crocker of Chichester; he has the real spirit of an experimentalist, but has not done much this summer.
