of -S. Dnomnondii, Bentli., and S. Wrif/ldil, Gray, but distinguished 

 from the former by its ligneous base and clearly perennial nature, 

 and from the latter by the form of the leaves, character of the pu- 

 bescence, smaller blue flowers, and less cucullate ujiper lip. Whilt! 

 it may ultimately prove to be a variety of ^S. WrigJitii, such a disposi- 

 tion of it in the absence of connecting forms and with the difference of 

 geographic occurrence would at present be unwarranted. 



Mi.MULUS CoNGDONii. Very small, at flowering subacaulescent ; 

 stems glandular-pubescent, becoming in iVuit 1 to 4 inches higii, much 

 branched near tlie base ; branches simple : leaves ovate or lanceolate, 

 obtuse, entire, dark purple beneath, \ an inch long, narrowed at base 

 to ciliate petioles of nearly equal, length ; peduncles in fruit 1-^ to 

 2 lines long, often reflexed : flowers very small; calyx-tube very 

 slender, prismatic, glandular-puberulent, moderately gibbous at base, 

 becoming strongly so in fruit, ending obliquely in short teeth, the 

 upper tooth the longest; corolla rose-purple, the slender tube 4 to 6 

 lines in length, with little or no distinctly enlarged throat, the sub- 

 regular abruptly spreading limb H to 2 lines in diameter; stamens 

 strongly didynamous, the upper pair much shorter and occasionally 

 with abortive anthers: style puberulent above; capsule cartilaginous, 

 very gibbous, laterally compressed, narrowed from a moderately broad 

 base, acute, deeply furrowed on the sides ; seeds minute, acute at each 

 end. — Collected by Mr. J. W. Congdon, in Mariposa County, Cali- 

 fornia, at Zimmerman's Ranch, in March, 1887, in April, 1888 

 (flowers and fruit), and in iMay, 1888 (fruit); also at Stockton Creek, 

 March, 1889 (flowers) ; and at Agua Fria (fruit). The diminutive 

 size and nearly acaulescent character of flowering specimens of this 

 plant made it at first appear probable that it represented merely a 

 dwarfed, early-spring form of one of the larger-flowered species. The 

 constant characters of Mr. Congdon's specimens, however, collected as 

 they were at different dates and localities, and representing verj' dif- 

 ferent stages of development, prove it a normal form and a distinct 

 species. While the vegetative habit is much like that oi 31. Kelloygii, 

 Curran, it is distinguished from that species by its much shorter co- 

 rolla-tube and smaller limb, as well as by its acute and not at all 

 oblong capsules. From M. pnlcheUns, Greene, it differs in its smaller 

 rose-purple corolla without the yellow lip, in its much shorter calyx- 

 teeth, and in other ways. In its short corolla-tube and very gibbous 

 capsule it resembles 31. latifoUus, Gray, but differs in its smaller size, 

 in its habit of branching from the base, (the stem of 3f. latifoUvs 

 although branching al)ove is simple below,) in its very slender calyx-
