Regmacarp

Taking the word Schizocarp as a type, I venture to suggest the term Achænocarp for the group of Achænes as used by Dr. [Alexander] Dickson, thus avoiding all confusion, and allowing the term Achæne to remain in its restricted sense. Regmacarp I would apply to the group of capsules, using the term capsule for one division of the group. […] The derivation of these terms at once explains their application. […] Regmacarp from regma, a rupture, in allusion to the dehiscence. […] In using these terms I would employ them in the following manner:— […] II. Dry Dehiscent Fruits. 3. Regmacarps. A. Follicle. Simple, dehisces by one suture. […]

The truth is, that it is impossible to find a classification of fruits which is founded on strictly scientific principles—the forms merging into each other; […] Accordingly, in the following classification, in which we have mainly followed Dr [Maxwell Tylden] Masters, all the less easily defined forms are omitted, and the list reduced as much as possible, without at all destroying its usefulness. […] monothalmic fruits. A. Ripe pericarp uniform. […] Fruits dehiscent.—II. Pods, or Regmacarps—viz., Follicle, Legume, Siliqua, Capsule, Pyxis.

Dr. Master's [i.e., Maxwell T. Masters'] modification of [Alexander] Dickson's and [William Ramsay] McNab's classification of simple fruits, as to primary kinds, is into 1. Nuts, or Achænocarps, dry and indehiscent; 2. Pods, or Regmacarps, dry, dehiscent; 3. Stone-fruits, or Pyrenocarps, fleshy without, indurated within, indehiscent; 4. Berries, or Sarcocarps, fleshy throughout, indehiscent.
