pressed hairs, the margins ciliate, several of the lower pairs 

 crowded, their winged petioles about icm. long; those of the 

 middle and upper part of the stem on successsively shorter peti- 

 oles, the internodes distant, ordinarily longer than the leaves: 

 inflorescence long-spicate, often 2dm. long, w^iorls distant, usu- 

 ally 3-5 flowered, the lowest pair of floral leaves two or three 

 times longer than the calyx, the others becoming successively 

 shorter, the uppermost shorter than the calyx: calyx funnel- 

 form, maximum length about 6mm., width at top 4mm., rather 

 densely pubescent with soft spreading hairs, the broad, ovate 

 lobes tipped with prominent spines, ribs not prominent: corollas 

 a little more than twice the length of the cah^x, pale, the tube 

 well exserted, upper lip pubescent on the outside, the broad 

 middle lobe of the lower lip commonly slightly deflexed, the 

 lateral lobes rather inconspicuous. 



No. 71 14, collected August 6, 1903, in moist places on the 

 banks of the Truckee river, one mile above Truckee, Nevada 

 county. This may be the plant referred to by Professor Greene 

 in Pittonia, 3: 341, under 6". littoralis as a form, but it seems to 

 be distinct from that species.

 most often linear, all prominently veined and pubescent on the
