New Species of South American Plants 129 



Species dedicated to Dr. Lindan who has kindly confirmed 

 my determination. 



Collected at Playa Brava on the northern coast of Colombia, 

 on a dry, rocky hillside on June 6, 1899, by Herbert H. Smith, 

 who reports it as a foot high, and having crimson flowers. (No. 

 2821.) 



Rondeletia colombiana. 



Pilose with somewhat appressed hairs. Stems slender, 

 quadrangular above. Stipules i cm. long, ovate, acuminate 

 and acute, thin, browa. Petioles 2 cm. or mora long, thin-mar- 

 gined. Blade (only one seen) 2 dm. long, i dm. wide, oval or 

 ovate with both ends very abruptly short-acuminate, thin, 

 bright-green, the slender venation prominent beneath, the 

 secondaries about 12 on a side, the lower widely spreading, then 

 falcate and erect, the upper erect-falcate, all coarsely pilose 

 beneath, the remaining venation finely and strongly anastomos- 

 ing. Panicle long and slenderly peduncled, loosely and openly 

 branched, the bracts elongated, narrowly linear, the flowers 

 inclined to be erect. Pedicels 3 to 5 mm. long. Calyx 7 mm. 

 long, the ovoid tube nearly as long as the 4 lobes, which are 

 slightly unequal, narrowly lance-linear and acuminate. Corolla- 

 tube strongly pilose, 12 mm. long, slender, slightly enlarged 

 two-thirds of the way toward the summit which is abruptly 

 expanded into a short throat. Limb 8 mm. broad, sub-rotate, 

 the lobes rounded. 



"Forest, Sierra de Onaca, 5,000 feet. A tree 20 feet high. 

 This appears to be the normal form, the specimen from Las 

 Nubes being from more or less stunted plants in second growth. " 

 (Herbert H. Smith, Colombia, No. 1813, in part.) Mr. Smith's 

 note refers to other specimens sent under the same number. 

 The two species are, however, obviously distinct, though closely 

 related. 



Rondeletia ovata. 



Inflorescence, lower leaf -surf aces, etc., gray-pilose with 

 appressed hairs. Stipules nearly i cm. long, lanceolate, acumi- 

 nate. Petioles to 12 mm. long, broad, keeled. Blades i to 

 1.5 dm. long, 4 to 7 cm. broad, with very abruptly contracted 

 and very shortly produced acute base and abruptly acummate 

 and acute summit, entire, thin, drying brown, the venation 

 prominent beneath, the secondaries about 12 on a side, strongly 

 falcate-ascending, rather stout, connected by numerous straight, 

 stoutish, short tertiaries. Panicle terminal, at length loose and 

 open, the bracts narrowly linear, to 7 mm. long. Pedicels 3 

 or 4 mm. long, rather stout, slightly thickened at the summit.
