148 New Species of South American Plants 



disposed to defer to the judgment of one so familiar with this 

 group, I can scarcely believe that so strong a generic tout en- 

 semble, especially when supported by this second species, should 

 fail of recognition. 



Kanitnia colombiana. 



Scabrous throughout, the branches numerous, erect, stout, 

 leafy at the summit. Petioles 4 to 6 mm. long, very slender, 

 the blades 2 to 3.5 cm. long. 6 to 10 mm. wide, lanceolate with 

 acutish base and acuminate and acute summit, entire, or with 

 a few small sharp teeth, thin, deep-green above, yellowish or 

 brownish beneath, the venation obscure on both surfaces, 3- 

 nerved, the midrib strong, the laterals rather faint. Panicles 

 contracted and head-like, densely flowered, somewhat leafy, 

 2.5 to 3 cm. broad and high. Heads very shortly and stoutly 

 peduncled or sessih, 6 mm. long, the bracts thin, ovate, acute, 

 nearly as long as the involucre, which is two-thirds the length 

 of the head, the scales oblong, acute, thick and rigid, strongly 

 ciliate or sub-fimbriate above. Akene, in flower, a little more 

 than 2 mm. long, the serrate pappus a little less than 4 mm., 

 the corolla-tube equaling the pappus, the lobes nearly a third 

 as long as the tube, ovate, obtuse. Exserted portion of styles 

 nearly as long as corolla-tube, flattened and broadened upward. 

 Mature akenes not seen. 



Label lost and locality doubtful, but probably collected by 

 Rusby and Pennell near Girardot, Colombia, July, 1917. 



Baccharis condensata. 



Youngest portions and lower surfaces of the young leaves 

 minutely and rather sparsely puberulent. Branches elongated 

 and slender, reddish-brown, leafy, more or less angled or sulcate, 

 the younger portions, like the peduncles and petioles, cortspic- 

 uously striate or costate. Leaves 7 to 10 cm. long, 12 to 30 

 mm. broad, the strongly cuneate petiole-like base more than a 

 fourth of the total length, dilated at the insertion. Blades 

 oblong-lanceolate, acute, entire, thick, deep-green, the slender 

 venation lightly prominent on both sides, the midrib very strong 

 on the lower surface, the secondaries sub-erect, the base decurrent 

 upon the midrib. Corymbs subsessile, the fertile densely 

 congested, with foliage leaves intermixed, the sterile openly 

 branched, densely flowered at the ends of the branches. 



Sterile Heads.^ — Involucre 5 mm. long, campanulate, the 

 scales thick, appressed, acuminate and acute, the receptacle 

 convex and papillose, the pappus sparse, coarse. Corolla- 

 tubes equally cylindrical, slender, 4 mm. long, the strongly 

 recurved, slender, fleshy, lance-linear lobes nearly half as long. 

 Style-branches slightly exceeding the corolla-tube, with brown, 

 obtuse, thickened appendages.
