Thanks TFC for his extremely interesting paper ["On the fertilisation of the New Zealand species of Pterostyles", Trans. & Proc. N. Z. Inst. 5 (1872): 352–7]. Has no doubt his explanation [of the fertilisation mechanism] is correct. The case is analogous to that of the Cypripedium though TFC’s case is much more curious.
Sends his paper on Selliera fertilisation [Trans. & Proc. N. Z. Inst. 9 (1876): 542–5]; contrasts it to CD’s description of Leschenaultia [Collected papers 2: 162–5].
Describes the irritability of Glossostigma elatinoides which he concludes is a mechanism to ensure cross-fertilisation.
Writes for CD, thanking TFC for his pamphlet on Selliera. CD was so interested that he ventured to forward it to Nature for publication.
