longation of the midnerve, on the margin ciliate or almost spinulose, at base 

 obtuse or rounded, glabrous above or somewhat strigillose on the midnerve only, 

 beneath densely strigillose on the primary nerves, sparsely so on the secondaries, 

 very sparsely on the surface, 3-pli-nerved with an additional pair of submarginal 

 nerves; secondaries straight, 4-7 mm. apart, diverging at an angle of 75-80°; 

 tertiaries obscure. Flowers 6-merous, solitary and almost sessile on the old 

 wood well below the leaves. Hypanthium broadly conic, glabrous, thick- walled, 

 6 mm. long to the torus. Calyx-tube prolonged 2 mm. to acute sinuses, the limb 

 prolonged about 0.8 mm. farther and very obscurely notched; exterior teeth none. 

 Petals red, about 9 mm. long, very asymmetric, the exposed margin entire, the 

 covered portion greatly widened, very thin and delicate with irregular margin. 

 Stamens 12, isomorphic; filaments stout, somewhat flattened; anthers straight, 

 4 mm. long; connective prolonged down the back of the thecae about 3 mm. as a 

 thin flat ridge, ending abruptly in a rounded tip. Ovary wholly inferior, ap- 

 parently 3-celled; ovules few. Style stout, glabrous, 11 mm. long; stigma capitate. 



TYPE; from lowland rain-forest, vicinity of Base Camp, foot of Cerro Sipapo,

Frutex arborescens ad 8 m.; ramulis cinereo-tomentulosis novellis striatis 

 vetustioribus obscure quadrangulatis; petiolis ad 2 cm. longis, laminis coria- 

 ceis 9-15 cm. longis 3.0-4.5 cm. latis eliiptico-lanceolatis, ad basim decurrenti- 

 bus (in sicco irregulariter recurvis), ad apicem acuminatis, ad marginem obscure 

 vel ad apicem evidenter repando-denticulatis, supra glabris nervis subtomentosis

 squamis ad apicem pulverulis, corolla extus modice glandulosa albido-viridi, 

 tubo 2.4-3.9 mm. longo lobis 2.5-2.8 mm. longis, achaenio 9-10-nervo turbinato

TYPE: shrub or small tree, along water course, central east drainage, Cerro 

 Sipapo, alt. 1800 m., Jan. 14, 1949, Bassett Maguire & Louis Politi 28366; New 

 York Botanical Garden. Paratypes, Cerro Sipapo, Maguire & Politi: small tree, 

 Carlo Profundo, vicinity of Carlo Negro, alt. 1600 m., 28272; small tree or shrub, 

 flowers^greenish-white, terraces, left fork, East Basin, alt. 1800 m., 28339. 



Closely related to Oliganthes schomburgkii Schultz-Bip., but distinguished by 

 2-3- rather than 3-4-flowered capitula, the much larger achenes, larger interior 

 pappus segments, the leaves with a dense reticulum of venules with minute darker 

 areolae (giving a punctate appearance to the upper leaf surface), and the at- 

 tenuate leaf bases which curl irregularly at least in the dried specimens. 



Orthopappus angustifolius (Sw.) Gleason. 



Corolla white, Culebra savanna, Rio Cunucunuma, Maguire & Maguire 29062. 



Mikania phelpsii Maguire & Steyermark. 



Subsucculent shrub 1 m. high, flowers white, summit West Peak, Cerro Sipapo, 

 alt. 1800 m., Maguire & Politi 21180. Known otherwise only from Ptari-tepuf, near 



Kavanayen, and Yavi. 



Mikania trinitaria DC. 



Slope forest, Cerro Sipapo, alt. 900 m., Maguire & Politi 28195.
