leaves 2-6 cm. long ; blades pinnately-lobed, the lower ones 

 long-petioled, the upper short-petioled ; lobes entire, ascend- 

 ing : racemes lax, few-flowered, 4-12 cm. long; pedicels spread- 

 ing or recurved, much longer than the calyx at maturity : calyx 

 sparingly bristly ; segments obovate or suborbicular, 4-6 mm. 

 long, obtuse, ciliate, variable in same calyx : corolla lilac or light 

 blue, 1 cm. broad ; segments rounded, entire, about as long as 

 the tube ; appendages present : stamens glabrous, shorter than the 

 corolla : capsules suborbicular, hirsute near the top. 



Diners from Phacclia pataliflora in the less dense pubescence 

 and in the petioled few-lobed leaf-blades. Besides these differences 

 in foliage, the short pedicels, the short obovate or suborbicular 

 calyx-segments and the smaller corolla (1 cm.) all furnish ready 

 means of separating Phacelia laxa from P. patuliflora. 



The type specimens were collected by Mr. Heller along Nueces
