SCROPHULARIA CE^. 



Sub-order I. — Antirrhinidae. Corolla 5-lobed or 3-lipped, imbricate in 

 the bud, the upper lip or two upper lobes outside. Inflorescence centripetal 

 or, in genera not Australian, compound. 



Sub-tribe I. — Eugratioleae. Leaves, at least the lower ones, opposite. 

 Stamens all inserted in the tube and (in the Australian genera) entirely 

 included. Capsule (in the Australian genera) opening loculicidally in two 

 entdre or bifid valves or 4-valved, or septicidal with bifid valves. 



Calyx tubular, 5-angled, 5-toothed. Anther-cells contiguous. — 1. 

 Mimulus. 



Calyx divided to the base or nearly so. Anther-cells more or less stipitate 

 or separated Tfrom each other. 



Dissepiment of the capsules splitting and forming the inflexed mar- 

 gins of the valves, leaving the two placentas free and separate. 

 Anthers of the longer stamens 1-celled. — 5. Adenosma. 

 Anthers all 2-oelled. — 4. Stemodia. 

 Diseeipiiment of the capsule splitting, but leaving the placentas con- 

 solidated in a single column. — 3. Morgiania. 

 Dissepiment of the capsule remaining entire, at least at the base, 

 and forming wiiiigs to the placental column. — 2. Ambulia. 

 Calyx divided to the base, the outer segment much broader than the 

 others. Anther-oells contiguous. — 6. Baoopa. 



Sub-tribe II. — Linderndeae. Stem-leaves opposite. Upper stamens per- 

 fect and included in the tube. Lower sptamems inserted in the throat, either 

 reduced to staminodia or with long arched filaments with an angle or small 

 liobe or appendage near the base, the lanthers contiguous or cohering under 

 the upper lip. Capsule opening in two entire valves parallel to the dis- 

 sepiment. 



Perfect stamens 4. — 9. Lindemia. 



Perfect stamens 2. Staminodia 2. Calyx divided to the base. — 10. 

 Ilysanthes. 



Sub-tribe III. Limoselleae. Small creeping or prostrate herbs, with 

 opposite or clustered leaves. Corolla (minute) with a short tube and five 

 aearly equal lobes. Anthers 1-celled. Capsule various. 



Capsule indehiscent or bursting irregularly or obscurely 4-valved. — 8. 

 Peplidium. 



Capsule loculicidally 2-valv6d. — 7. Microcarpia«a. 



Suborder II. — Bhinanthideae. Corolla either with 4, 5 (or rarely more 

 in genera not Australian) spreading lobes, variously imbricate in the bud, 

 the upper onea very rarely outside, or 2-lipped with the upper lip inside. 

 Inflorescence centripetal, or very rarely in genera not Australian, compound
