SCROPHULARINE^E. 279 



1. G. ebracteata, Benth. Glabrous, obscurely viscid, erect, 25 in. 

 high: leaves lanceolate, acute, mostly entire: calyx with no bractlets at 

 base, the segments almost equalling the small yellow-throated white 

 corolla: capsule globose. Low wet places in fields; Sonoma Co., Bioletli. 



13. ILYSANTHES, Raf. Slender glabrous low annuals, with opposite 

 sessile leaves and filiform naked peduncles in their axils, the upper 

 becoming racemose by the reduction of the subtending leaves to bracts. 

 Calyx 5-parted; the divisions subequal. Upper lip of corolla short, 

 2-lobed, erect; lower larger, 3-cleft, spreading. Only 2 stamens fertile, 

 these included, their anthers 2-celled; sterile anterior pair inserted high 

 in the throat of the corolla, each of an .unequally 2-lobed filament; 

 shorter lobe small, tooth-like, the longer glandular. Many-seeded small 

 capsule 2-valved; edges of the valves separating from the partitions, 

 these being left with the undivided placenta. 



1. I. gratioloides (L.), Benth. Diffusely branching, 37 in. high: 

 leaves ovate or oblong, sparingly toothed or entire: peduncles surpassing 

 the leaves, in fruit divergent: corolla light purple or bluish, 3 4 lines 

 long. Muddy banks of the lower San Joaquin. July Oct. 



14. PL ANT AGIN ELL A, Ruppius. Glabrous dwarf annual with run- 

 ning stems putting forth at their ends clusters of narrow entire fleshy 

 leaves; 1-flowered scapes. Calyx and nearly regular corolla campanu- 

 late, 5-toothed and -cleft. Stamens 4, nearly equal; anthers with con- 

 fluent cells. Style short, clavate; stigma thickish. Capsule globose, 

 many-seeded, 2-valved; valves separating from the thin partitions; 

 placentae remaining central. 



1. P. aquatica (L.), Moench. Leaves with petioles longer (when 

 growing in water much longer) than the spatulate-oblong or oval blade, 

 and exceeding the scapes, but the whole leaf usually only 1 3 in. long: 

 corolla very small, white or purplish. Margins of fresh water ponds 

 and lakes on the San Francisco peninsula; usually terrestrial only. 



15. VERONICA, Fuchs. (SPEEDWELL). Herbs, with at least the 

 lowest leaves opposite. Flowers small, white or blue, in racemes, or 

 solitary in the axils. Calyx and nearly rotate corolla each 4-parted; 

 lower lobe of the latter, and sometimes the lateral ones, narrower than 

 the upper. Stamens 2, one on each side of the uppermost corolla-lobe? 

 exserted; anther-cells confluent at apex. Stigma somewhat capitate. 

 Capsule compressed, 2-lobed, or at least emarginate, few many- seeded; 

 dehiscence loculicidal. 



1. V. Americana, Schwein. Perennial, glabrous, the decumbent 

 stems ^2 ft. long; herbage rather fleshy: leaves oblong, serrate, 

 truncate or slightly cordate at base, short-petioled: racemes opposite, 

 slender peduncled, many-flowered: pedicels slender: corolla blue, with 

 purple stripes: capsule turgid, many-seeded. Shallow margins of 

 streamlets, growing in sand or gravel.
