J 82 Plants Collected in Paraguay. 



Petunia Tiolacea, Lindl., Bot. Reg., 1. 1626. 



Asuncion (185). August-September. 



As I always found this Petunia in the neighborhood of dwelling- 

 houses and in waste grounds where house rubbish was dumped, I 

 thought it probably a garden escape, but as it occurs native in 

 Southern Brazil (Fl. Bras., x, 172) it may well be a native plant 

 of Paraguay.

8ch\irenkia Americana^ L., Sys. Nat., iii, 62. 



Asuncion (112). November-December. = Balansa 21^1. 



The Schwenkias, of which there may be 20 species, all but one 

 confined to South America, were formerly classed in Scrophularinese, 

 but now placed by Bentham and Hooker in Solanaceae. The species 

 here noted is a frutescent plant about 6 dm. in height, with pubes- 

 cent stem, leafy below, with a large terminal panicle of slender, 

 naked branches. Leaves with blades 3-t cm. long, rounded or 

 semi-cordate at base, on petioles 5-12 mm. in length. The flowers 

 are peculiar. Calyx scarcely 3 mm. long, with 5 minute ovate 

 lobes. Corolla very slender, tubular, about 10 mm. long, lurid 

 purple, 5-nerved, with a thick, green, glandular border that closes 

 in 4 lobes over the stigma, from the 4 corners of w^hich project 4 

 clavate teeth. Fruit a globular capsule, 3 or 4 mm. in diameter, 

 1-celled, many-seeded, dehiscing by 2 valves. Seeds pitted, com- 

 monly hexagonal.
