New Species of South American Plants 109 



ducing a great many fibrous roots. Branchlets erect, i to 3 cm. 

 high, densely matted, stout, the leaves densely imbricated, 

 sessile 1.5 to 2 cm. long, 3 to 6 mm. broad, oblanceolate with 

 long-acuminate base and obtuse summit, ths upper portion 

 incisely serrate, about 3 teeth on each side. Thick, apparently 

 fleshy when fresh, rigid when dry, uniformly gray-green. 

 Heads terminal, short-peduncled, at length i cm. or more long 

 and 4 or 5 mm. broad, the scales very densely imbricate. Floral 

 bracts about 3 mm. long and nearly as broad, the broad claw 

 about one-third of the length, the broad rounded summit ciliate 

 and sharply mucronate. Calyx campanulate, strongly com- 

 pressed so as to have a similar form to that of the bract, but 

 with a deeply notched summit, the lips being transverse to the 

 compression. Corolla 3 mm. long, the tube abruptly much 

 contracted above the base, the throat rather abruptly expanded, 

 the upper lip nearly twice as long as the lower, very broad, with 

 nate margin, the lower 3-lobed, the lobes spreading. 



"Growing in dense mats, in sand, at Mollendo, Peru, sea- 

 level, the flowers blue, August 5, 1901." (R. S. Williams, No. 

 ere 2933.) 



Salvia tenuistachya. 



Inflorescence minutely puberulent. Stems slender, sharply 

 angled above. Upper petioles indistinguishable from the 

 acuminate leaf bases, some of the lower up to 3 or 4 cm. long, 

 slender. Blade 6 to 12 cm. long, 3 to 7 cm. broad, ovate and 

 somewhat rhomboidal with the base abruptly contracted into 

 the petiole and the summit abruptly acuminate and acute; 

 coarsely serrate with acute teeth and sinuses, thin, bright 

 green, the slender venation slightly prominent beneath, the 

 secondaries three on each side, sub-erect, connected by few 

 crooked tertiaries. Racemes simple or branched at the base, 

 much elongated, narrow, the whorls subtended by deciduous 

 lanceolate attenuate bracts, the lower mostly 6-to 8-flowered, 

 the pedicels about as long as the calyx in the fruiting stage, 

 half as long in flower. Flowering calyx 4 or 5 mm. long, sharply 

 five-ribbed, the tube narrowly campanulate, the lips about a 

 third of the total length. Upper lip entire, the lower a little 

 longer, bifid, all acuminate and acute. Corolla 8 mm. long, 

 the lips nearly half of the length, the upper entire, and concave, 

 the lower three-lobed, its middle lobe narrower. Filaments 

 1.5 mm. long, thick, the connective much thickened, the upper 

 branch about as long as the filament, attenuate toward the 

 summit and attached at about the middle of the slender anther 

 cell. Lower branches of the connectives connate in their 

 lower two-thirds, and a little longer than the upper. Lower 

 style-branch short, broad, obtuse, the upper elongated and 

 filiform.
