New Species of South American Plants 151 



acuminate lobes about a fourth of the length, strongly recurved, 

 the recurved style-branches long-exserted. Akenes oval, 

 strongly compressed, short-stipitate, pilose. Sterile akenes 

 turbinate, half as long as their corollas, bearing a pappus of 

 fine, short, soft white hairs. Sterile corollas shorter than the 

 fertile, broadly cylindric-campanulate, lobed a third of the way, 

 the lobes ovate, obtuse, densely pilose. Anthers black, nearly 

 equaling the erect corolla-lobes, the style about equalling the 

 latter. 



Collected by Herbert H. Smith in the Santa Marta moun- 

 tains, but without number, locality or date. 



Baltitnora ovata. 



Sparsely white-pilose on the inflorescence and younger por- 

 tions and on the lower leaf surfaces, harshly strigose on the 

 upper leaf-surfaces. Stems slender, 3 to 4 feet high, loosely 

 branched, the branches very slender and sparsely leaved and 

 flowered. Upper leaves only seen, their petioles slender, 5 to 

 20 mm. long, the blades 4 to 10 cm. long, 1.5 to 4 cm. broad, 

 lance-ovate, abruptly short-acuminate at the base, long-acumin- 

 nate at the summit, lightly crenate-dentate or serrate, a pair of 

 slendar nerves starting from near the base, the venation not 

 conspicuous. Inflorescence sparsely bracted, the peduncles 

 filiform, mostly 10-15 rnrn- long. Heads 3 to 4 mm. long and 

 broad, the involucre approximately hemispherical-cupulate. 

 Involucral scales about 8, ovate or lanceolate, finely nerved and 

 pilose, unequal. Ray-corollas wanting. Akenes of the ray- 

 flowers 2 or 3, turbinate, the pappus of 5 sub-equal scales, the 

 akenes at length about equaling the involucral scales, black, 

 turgid, strongly tuberculate, the summit convex. Scales of 

 the disk floweis 2 or 3, oval, nerved. 



"Common on hot dry plains and rocky hills within 3 or 4 

 miles of the sea at Cienaga, Papare, Santa Marta, Braba, etc., 

 September to November." (Herbert H. Smith, No. 536.) 



Montanoa serrata. 



Strigose throughout. Branchlets ascending, slender, sul- 

 cate, leafy, the upper leaves alternate. Petioles i to 1.5 cm., 

 long, slender, mostly divaricate, or some recurved, the blades 

 thin, 5 to 10 cm. long, 2 to 4 cm. broad, ovate, the base blunt, 

 many of the smaller slightly inequilateral, regularly long-acumi- 

 nate and acute at the summit, serrulate with mucronate teeth 

 and acute sinuses, slenderly 3-nerved, the venation inconspicu- 

 ous Heads rather few, loosjly paniculate, slenderly peduncled, 

 6 to 8 mm. long, exclusive of the rays. Involucre campanulate, 

 about 4 mm. broad, and 6 mm. long, the scales 2 or 3 serialled, 

 narrow, acuminate, erect or the tips slightly spreading. Rays
