Plants Collected in Paraguay. 63 



5-15 mm. long; stipules lanceolate, acute, 12 mm. long, 4 or 5 mm, 

 broad. Flowers small, yellow, in an elongated, naked panicle. 

 Calyx 5-lobed, the lobes f as long as the petals and very hairy. 

 The variety is much more slender, much branched from the base. 

 Leaves shorter and narrower ; stipules 4 or 5 mm. long, setaceous 

 or 1 mm. broad at the base. Inflorescence in a contracted terminal 

 panicle, or a few flowers at the ends of the branches. Both occur- 

 ring near Caballero and Yilla Rica.

Climbing, softly pubescent, branched, tlie twigs channeled. Leaves short- 

 petioled, lanceolate, rather coriaceous, obscurely reticulate, blunt-pointed, 

 remotely dentate near the apex or entire, glabrous above, slightly pubescent 

 beneath, 4-6 cm. long, about 1 cm. wide ; flowers in short, axillary cymes ; 

 lamina of the petal filiform ; fruit globose-ovoid, about 1 cm. in diameter, the 

 spines conic acute, 3-4 mm. long ; seed obliquely oblong, brown, smooth, 

 rounded on the back, the sides nearly flat. 



In thickets, Asuncion (288). December. Same as Balansa's 2002. 



1 do not use the generic name Biittneria, Loefl., because it is a 

 homonym of Butneria, Duhamel = Calycanthus, L. N. L. B. 



A singular liana which is not uncommon in the thickets around 

 Asuncion. The stems are armed with small, recurved prickles, by 

 means of which it climbs upon shrubs and low trees. It clings so 

 closely to its supports that it is difficult to detach the branches. 

 The largest leaves I found were 12 cm. in length by 5 cm. broad, 

 and often had small prickles along the midrib beneath, with a petiole 



2 mm. to 2 cm. long. Calyx monosepalous, with 5-pointed segments 

 longer than the corolla. The whole flower is greenish-yellow in 

 hue, and quite peculiar in appearance. The petals are flat at the 

 base and 2-lobed, throwing up what appear to be 5 yellowish horns, 

 which are the most conspicuous part of the flower. The capsule is 

 normally 5-carpelled, but often several of the cells of the ovary are 

 abortive, and not more than 2 or 3 of the ovules ripen into seeds. 

 The fruit is down-covered, and has a curious prickly look about it.
