302 PITTONIA. 



paiiiculately branching, the verticillasters forming unilateral 

 racemes. Bracts and floral bractlets small, reflexed, cuspidate- 

 tipped. Calyx and corolla strongly bilabiate, the latter with 

 slender tube, almost obsolete upper lip, the lower lip greatly 

 elongated (a half-inch long), narrowed at base, abruptly con- 

 stricted in the middle, folded abruptly backward over the 

 tipper lip and the tube, concealing both. Filaments dilated, 

 inserted on the middle ol the lower section of the lip ; anther- 

 iferous connective of each elongated and exserted, extending 

 backward toward the calyx by inversion of the corolla-lobe 

 bearing it; sterile connective greatly reduced, appearing as 

 a prominent tooth. Style slender, long-exserted, bent abruptly 

 to one side near the base, and protruding laterally from the 

 corolla at almost a right angle. 



That the very odd and highly complicated structure of the 

 flower in this common plant should never have been made out 

 even approximately by any of the masters of herbarium 

 work, is evidence of the insufficiency of the data which such 

 materials furnish, where accurate knowledge of these organs 

 is needful to determine affinities. There is no ISalvia or 

 Audihertia which maTkes the slightest approach to Ramona 

 in the cut of the corolla. Its lower lip is not only thrice the 

 length of all the rest of the flower, but is fiddle-shaped, the 

 two lobes of this body being folded first downwardly the 

 Tipper upon the lower one, and then the whole body, thus 

 doubled, is laid back over the tube, throwing the long-exserted 

 stamens (whose foothold is upon one of these lobes) backward 

 so that their anther cells lie down toward the orifice of the 

 calyx; and then the style, coming out at one side of the 

 closed orifice of the corolla, is bent squarely about in order 

 that the stigma may be near the anther-cells. The one 

 species is
