Working on monstrous Primula. Is ovule anatropous as Asa Gray says, or amphitropous? Does he know natural path of pollen tubes in Primula. Can the tube enter the ovule by the chalaza?

Encourages JS to publish on sterility of orchids and to experiment on Passiflora.

Doubted Hooker’s poppy case.

Thanks for CD’s Linum paper [Collected papers 2: 93–105].

Has not published much because he would be ignored as a gardener; hence he is looking for a foreign appointment.

Has prepared orchid sterility paper at CD’s suggestion [Trans. Bot. Soc. Edinburgh 7 (1863): 543–50].
