New Species of South American Plants 161 



This species is very near L. fulvo-tomentosum O. Kuntze. 

 It appears by its superficial characters to be the same asTriana's 

 102 and 1140 and Kalbreyer's 650. 

 Liabutn falcatutn. 



More or less floccose-puberulent, with the exception of the 

 upper leaf -surf aces. Stems erect or ascending, a meter high, 

 only the upper portions seen, slender, sub-quadrangular and 

 lightly sulcate, the internodes 12 to 18 cm. long. Petioles about 

 I cm. long, stoutish, the blades 6 to 12 cm. long, 2 to 4 cm. broad,, 

 long-acuminate and acute, abruptly contracted into the petiole, 

 more or less falcate toward the summit, serrate with very small 

 ascending teeth, white underneath, where the 3 slender brown 

 ribs, starting from the summit of the petiole, are conspicuous, 

 green above, where the venation is not conspicuous, thin. 

 Panicles crowded in a terminal corymb, with occasional smaller 

 ones in the upper or lower axils, stoutly peduncled, the flower- 

 ing portion 2 to 3 cm. long, linear-bracted, the peduncle and 

 rachis brown- tomentose, the heads mostly sessile or very short- 

 peduncled. Heads about 8 mm. long, the involucres nearly 

 equaling the pappus, its scales in about 6 series, the outer short, 

 ovate, acute, thick, the innermost thin, long-acuminate and 

 acute. Ray-corollas exceedingly slender, not or little exceeding 

 the involucre. Disk flowers numerous, the corollas yellow, the 

 exceedingly slender tube expanded abruptly into the limb, 

 which is half as long as the tube and three times as wide, and 

 lobed more than half way down. Anthers small, the cells 

 obtuse at the base. Style slender, little exceeding the anthers, 

 its branches short. Akene small and slender, hispid. Outer 

 pappus sparse, short and slender, the inner copious, slender, 

 short-plumose. Receptacle densely chaffy, the chafif slender, 

 acuminate and acute. 



"Rare on rocks on the banks of streams in the forest, 1500- 

 3,000 feet. January 20." (Herbert H.Smith, No. 2012.) 

 Liabum acuminatum. 



White-floccose throughout, except the upper leaf-surfaces. 

 Stems slender, erect or ascending, angled and sulcate, the inter- 

 nodes 3 to 5 cm. long, or the uppermost much longer. Petioles 

 slender, 8 to 16 mm. long, the base lightly dilated and clasping. 

 Blades 6 to 12 cm. long, i to 3 cm. broad, lanceolate, the base 

 acuminate, the summit long and narrowly acuminate and acute, 

 finely serrate with salient teeth, 3-nerved, the lateral pair start- 

 ing from the midrib above the petiole and running near the 

 margin. Corymb terminal, linear-bracted, small, densely flower- 

 ed, the heads sessile or very short-peduncled, occasionally 

 smaller corymbs in the upper axils. Heads about 6 mm. long, 

 the involucre nearly equalling the pappus, campanulat2, the
