Type: VEXEZI T ELA: Estado Bolivar, Rio Pargueni, Rio Orinoco, frequent 

 at river edges 1-10 km above mouth, alt. 90 m, tree 3 m, fls. purple, Dec 10, 1955, 

 J. J. Wurdack and J. V. Monachino 39769 (holotype XV. isotype K). 



VENEZUELA: Estado Apure: Rio Cinaruco, Rio Orinoco, locally frequent between 

 mouth and Las Galeras de Cinaruco, alt. 80-90 m, shrub 3 m, fls. purple, Jan 25, 1956, id. 

 41365 (NY, K). 



The large leaves of sterile shoots, which I have described above and which, 

 it is interesting to note, retain the small number of pinnae, were taken from a 

 single example of the "population" from which the flowering specimens of no. 

 39769 were collected. Dr. Wurdack writes that "the plants of 39769 were very 

 abundant along the Pargueni, but were fknvering sporadically, so the collection 

 number probably represents at least 6 different plants. '* 



The two collections are not uniform, no. 41365 showing leaves with more 

 numerous pinnae and shorter calyx lobes than those of 39769, but I am confident 

 that they represent a single entity which is of interest because of its apparent 

 relationship in floral characters with two species, J. hesperia and J. caucana. 

 and especially the former, with a very different distribution in Colombia (see 

 Dugand, Mntisia 23: 1-11. 1954). The other somewhat similar species of sect. 

 Monolobofy J. obtusifolia H. & B. which, with its vars. obtusifolia and rhombi- 

 folia, is Veil known in the Orinoco basin, is at once distinguished from J. orino- 

 C( nsis by the numerous leaflets of the usually more numerous pinnae, by the 

 inflorescence arising from old wood, the shortly deltoid teeth of the calyx, and 

 the absence of glandular hairs on the outside of the corolla tube towards its base. 



Lundia densiflora DC. 



VENEZUELA: Estado Bolivar: woody vine, corolla white with pale yellow tube, com- 

 pletely white with age, Rio Parguaza, occasional on crystalline laja along river 2 km below 

 Raudal Maraca (about 110 river km from mouth), 120-150 m, fl. Dec 1955, J. J. Wurdacfy & 

 J. V. Monachino 41026. Colombia,' Guiana, Amazonian Brazil. First record for Venezuela. 



Memora flaviflora (Miq.) Pulle, forma. 



VENEZUELA: Estado Bolivar: woody vine climbing 18 m on trees, calyx greenish, 

 corolla yellow-orange, Rio Parguaza, locally frequent on river banks 1-3 km above El Carmen 

 (about 50 river km from mouth), 110 m, fl. Dec 1955, J. J. Wurdack 4' J. Y. Monachino 40950. 

 Guiana. First record for Venezuela.
