From Fritz Müller 1 December 1866
Summary
Gives observations on orchid ovules ripening long after blooming.
Infertility with own pollen sometimes does and sometimes does not indicate dimorphism; gives observations on Ximenia, Eschscholtzia and Oncidium flexuosum.
Describes some striking seeds eaten by birds,
and some new dimorphic species.
Variation in Thillia.
Confirms CD’s suspicion that the lancet-fish [Amphioxus] lives in competition with invertebrates: it shares its habitat with a similar-looking Ophelia, which is quite unlike other annelids, just as the lancet-fish is unlike other fishes.

I am now in a position to give you two new examples of plants that have conspicuous seeds stuck to the valve of the fruit. One is a small tree of the Meliaceae, probably a Guarea. The plant has eight brick-red seeds stuck to the valve of the fruit (they are too big to be sent in a letter). The other is a big tree of the genus Talauma (Magnoliaceae). I still remember my surprise about 12 …
