Order 68. SCROPUULARIACI^^. (Figwort Family.) 



Chiefly herbs (rarely trees')^ with didynamous or diandrous (or very rarely 

 6 perfect) stamens inserted on the tube of the flipped or more or less irveffu- 

 lar corolla^ the lobes of which are imbricated in the hud: fruit a 2'CeUed and 

 usually many-seeded podj with the placentce in the axis : seeds anatropous, 

 with a small embryo in copious albumen. — Style single : stigma entire or 

 2-lobed. Leaves and inflorescence various ; but the flowers not terminal 

 in any genuine representatives of the order. — A large order of bitterish, 

 some of them narcotic-poisonous plants : the two principal groups generally 

 distinguishable by the aestivation of the corolla.

the bud (with occasional exceptions in Mimulus, &c.). Pod usually 

 septicidal.

 raceme. Leavfes all alternate. 



1. 'Verba§ciiin. Stamens 5, all with anthers, and 3 or all of them with bearded fi.Iaments.

 Pod 2-4-vaIved. Leaves opposite. Inflorescence usually compound ; the flowers in small

6. Clielone. Corolla tubular, inflated above. Sterile stamen shorter than the others. 



Anthers very woolly. Seeds winged. 



7. Pentstemon, Corolla tubular. Sterile stamen about as long as the rest. Seeds wingless. 

 Tribe IV. GRATIOLB.^. Corolla tubular, not saccate nor spurred. Pod 2-Talved. 



Inflorescence simple •, the flowers being single in the axil of the bracts or leaves, the pe- 

 duncles bractless. Leaves all or the lower ones opposite. No rudiment of a fifth stamen. 

 # Stamens 4, all anther -bearing and similar. 



8. Mimulus. Calyx prismatic, 5-angled, 5-toothed. Corolla elongated, 



9. Conobea. Calyx 5-parted, the divisions equal. Corolla short. 



10. Herpestis. Calyx 5-parted, unequal, the upper division largest. Corolla short. 



* * Anther-bearing stamens 2 : usually also a pair of sterile filaments. 



II. Gratiola. Calyx 5-parted. Stamens included ; the sterile pair short ornone. 



12. Ilysanthes. Calyx 6-parted. Stamens included } the sterile filaments protruded. 



11. RHINANTHIDE^. Under lip or the lateral lobes of the corolla 



covering the upper in the bud. Pod commonly loculicidal. 



Tribe V. SIBTHORPIE^E, VERONICE.^, &c. Corolla wheel-shaped, ealver-
