146 PROCEEDINGS OF THE ACADEMY OF [May~Oct., 



bracteolate. Stem quadrangular, the angles ridged or 

 slightly winged. 

 Sepals united over one-third length. Filaments all with 

 anthers. Seeds not with transverse lines. Leaves 

 petioled, serrate-dentate. Angles of stem slightly 

 winged. 

 Pedicels 1-2 mm. long. Sepals united nearly one- 

 half their length, much shorter than the capsule. 

 Corolla straight, the tube strongly horizontally 

 flattened, the posterior lip purple-brown, else- 

 where corolla white throughout, pubescent within 

 on ridges to antero-lateral sinuses; the free por- 

 tions of the anterior filaments appearing as up- 

 curved from the apices of these ridges. Capsule 

 accuminate, finely pubescent to glabrous. Seeds 

 tuberculate. Leaves oval, rounded, narrowed at 

 base. Plant repent, pubescent. 



13. Vandellia. 

 Pedicels 10-25 mm. long. Sepals united over three- 

 fourths length, equaling or slightly longer than 

 the capsule. Corolla decurved, the tube scarcely 

 or not flattened horizontally, blue or white, gla- 

 brous within on the ridges to antero-lateral sin- 

 uses; the free portions of the anterior filaments 

 appearing as outgrowths proximad to the apices 

 of these ridges which therefore terminate as short 

 knobs. Capsule mucronate or acute, glabrous. 

 Seeds shallowly pitted. Leaves ovate or lanceo- 

 late-ovate, acute, truncate-cuneate at base. Plants 

 repent to erect, glabrous. 14. Torenia. 



Sepals distinct or nearly so. Antero-lateral filaments 

 without anthers. Seeds with fine transverse lines. 

 Leaves sessile, mostly clasping, slightly crenate or 

 entire. Angles of stem ridged, not winged. Corolla 

 blue. Plant diffused-ascending, glabrous. 



15. Ilysanihes. 

 Leaves pinnatifid. Capsule linear-attenuate in outline. 

 Seeds regularly cylindric, spirally ridged, disposed in one 

 row within each valve of the capsule. Corolla purple- 

 blue. Plant low, branched, erect. 16. Schistophragma. 



II. MIMULEAE. 



Capsule oblong, dehiscing loculicidally, its walls dry, mem- 

 branous, brownish. Calyx-tube longer than and enclos- 

 ing the capsule, its ribs slightly winged, its lobes decidedly 

 unequal, the posterior longest. Corolla 10-15 mm. long, 

 yellow, with many red-brown spots within throat on the 

 anterior side. Leaves broadly ovate, shortly petioled, 1-4 

 cm. long. Inflorescence of axillary simple pedicels. Stem 

 obscurely angled, not winged. Plant low, repent-ascend- 

 ing. 17. Mimulus.
