1832 Encycl. Brit. V. 42/1 When a capsule opens transversely, it is called a pyxidium.

1857 A. Henfrey Elem. Course Bot. 143 The Pyxidium is a one- or more-celled, many-seeded fruit, the upper part of which falls off like a lid by circumscissile dehiscence.

1909 A. F. M. Johnson Text-bk. Bot. for Students i. iv. 64 In the Scarlet Pimpernel..the top of the capsule comes off as a lid... This form of capsule is called a Pyxidium.

1946 Amer. Jrnl. Bot. 33 681/1 Dehiscence in the pyxidium cannot be accounted for completely by differential drying. It occurs while both halves of the fruit still contain living cells.

1993 A. H. Gentry Woody Plants Northwest S. Amer. (1996) 497 The fruit of most genera [of the Lecythidaceae] is a pixidium, or ‘monkey pot’, with an operculate lid that comes off to release the seeds.
