Isle, August 16, 1880, by Gustave Guttenberg, and a large bundle of 

 typical material collected September 9—11, 1900, by J. A. Shafer. 



The specific name incurvum is given this species from the quite 

 strongly and sharply incurved callosities, a constant character, which 

 will at once serve to distinguish this species from lbidium cernuum 

 (Linnaeus) House. Perhaps the most closely related species is the more 

 southern lbidium odoratum (Nuttall), which ranges from Virginia and 

 Kentucky southward through the Gulf States, but the differences are, 

 nevertheless, quite marked between the two species.

22. Passiflora Warmingii Mast, subsp. chacoensis Pries, 1. c, p. 4, tab. 

 I, fig. 7—8. 



Herba laeteviridis, glabriuscula, in partibus omnibus pilis laxis molli- 

 bus minutis obsita. Laminae foliorum tenuiter membranaceae, supra laete- 

 virentes, subtus glaucae, utrinque minutissime pilosulae, profunde trilo- 

 batae, lobis ovatis, acutis vel obtusiusculis, irregulariter crenatis, basi 

 exquisite contractis (i. e. incisuris angustis, lobis invicem fere attigenti- 

 bus vel rarius etiam paulo tegentibus): laminae circ. 9 cm longae et 

 10 cm latae. Baccae pilis tenuibus, mollibus obsitae. 



Bolivia: Gran Chaco, ad Portin Crevaux (17. IV. 1902; Pr. 1600; 

 floribus fructibusque ornata). 



In den dichten Uferwaldern, hauptsachlich von der Composite 

 Tessaria integrifolia gebildet, welche den oberen Teil des Rio Pilcomayo 

 im Chacogebiete umgeben, kam diese Passiflora reichlich vor, einen 

 charakteristischen Bestandteil der Untervegetation bildend. Sie steht 

 P. Warmingii Mast, sehr* nahe;' jedoch ist sie stets durch eine ver- 

 schiedene Blattform ausgezeichnet, weshalb ich sie als Unterart derselben 

 aufstelle.
