of the short slender branches of the subterranean caudex, very 
slender, glabrous, erect, 2-3dm. high: basal leaves rosulate on 
the crowns, relatively few, oblong-oblanceolate, 1.5—3 cm. long, 
tapering into very short petioles; stem leaves about 3 pairs, those 
of the lowest linear-spatulate, the others linear and smaller: 
flowers few, in an open obscurely glandular-pubescent cymose 
panicle with subulate bracts: sepals ovate, acute, often purplish, 
with scarious margins, 5-7mm. long: corolla _bluish-purple, 
tubular-funnel-form, about 2cm. long, the lips unequal; lower

It seems rather superfluous to add new names to our already long list, 
but the following numbers from WALKER’s collections are so aberrant that 
one hesitates to refer them to a known species without some explanation: 
no. 360, Paradox, August 1; no. 537, Coventry, Sept. 2; no. 434 (less typical), 
San Miguel Canon, August 10, 1912.
