410 SCROPHULAKIACE^. 



1. 1. gratioloides Benth. Diffusely branching, 3 or 4 in. high, 

 the stems and branches very slender; herbage glabrous; leaves ovate 

 or oblong, 4 to 8 lines long, sparingly denticulate or entire; peduncles 

 long and slender, several times longer than the flowers, solitary in the 

 axils or subracemose above by the reduction of the subtending leaves 

 to bracts; calyx 1 line long; corolla 3 to 4 lines long, bluish. 



Muddy shores of the lower San Joaquin. Aug.-Sept. 



15. SYNTHYRIS Benth. 



Perennial herbs with the rounded petioled leaves in a radical tuft. 

 Flowers racemose. Calyx 4-parted. Corolla with very short tube 

 and 4-lobed rotate-campanulate limb. Stamens 2, inserted close to the 

 upper sinuses, exserted. Anther cells parallel, not confluent. Cap- 

 sule compressed, loculicidal. (Greek sun, together, and thuris, a little 

 door, referring to the continued adherence of the base of the valves to 

 the placentse.) 



1. S. rotundifolia Gray. Plants 2J to 5 in. high; herbage 

 appressed-scabrulose; leaves ovate-cordate, doubly crenate, 2 in. long, 

 shorter than the petioles; peduncles scarcely longer than the leaves; 

 inflorescence loosely corymbose-racemose; the bracts small and the 

 pedicels, at least the lower, several times longer than the flowers; 

 corolla white, 2 lines long; capsule scarcely known. 



Cataract Gulch, east slope of Bolinas Eidge, Chesnut and Drew, 

 Apr. 17, 1891; Cazadero, J. Burtt Davy, Mar., 1895; hills near Mad 

 River, Marshall, Jan., 1887. Nearly related to S. reniformis Benth. 

 of Oregon and Washington state; but that species is nearly glabrous, 

 with reniform leaves shorter than the scapes, the pedicels very much 

 shorter than the bluish flowers (which are disposed in a short dense 

 raceme), and the capsule emarginate. 



16. VERONICA L. Speedwell. 

 Ours herbs with opposite leaves and flowers in axillary or terminal 

 racemes, or solitary. Pedicels without braotlets. Calyx in ours 

 4-parted. Corolla subrotate, deeply 4-oleft, the upper lobe commonly 

 broader than the lateral lobes or the lower one. Stamens 2, o-ne on 

 each side of the upper corolla-lobe, exserted. Stigma entire. Cap- 

 sule flattened, often obcordate. Seeds few to many. (Name thought 

 to be in memory of St. Veronica.) 



Mowers solitary in the axils, the leaves alternate or the lowest opposite: 

 annuals.
