Encloses MS of his paper ["On individual sterility of Oncidium", J. Linn. Soc. Lond. (Bot.) 8 (1865): 162–7].

His next will be on Passiflora, Disemma, and Tacsonia [J. Linn. Soc. Lond. (Bot.) 8 (1865): 197–206].

When he receives proofs of his Primula paper he will add CD’s case about equal-styled cowslip.

Thanks for communicating Oncidium sterility paper [see 4485] to Linnean Society.

Surprised that CD’s seedlings of non-dimorphic cowslip breed true.

Surprised also that the red primrose he sent reverts to wild form. He had reasoned from red’s infertility with yellow that it was an established variety. Tries to correlate inheritance of colour and sterility between varieties.

Discusses the negative testimonial provided him by James McNab.

Sends testimonial from J. H. Balfour.

Would be glad if offered the sort of colonial opportunity Hooker suggests.
