Plants Collected in Paraguay. 181 



Common both in the Argentine Republic and Paraguay. A very 

 bushy shrub, 1-2J m. high, with clusters of pale yellow, tubular 

 flowers. Fruit an oblong purple berry-like capsule. Often grown 

 in gardens at Asuncion, and common in thickets about the city. 



]¥icotiana glaiica, Graham, Bot. Mag., t. 2837. 



Asuncion (38). 



Usually a shrub, but sometimes a small tree 5-7 m. in height. 

 Stem and leaves glaucous, the latter ovate, acute at apex and 

 rounded or cuneate at base, on petioles 3 or 4 cm. long. Flowers 

 very numerous, in large, naked, terminal, drooping clusters or pani- 

 cled racemes. Corolla yellow, tubular, 4 cm. long, glandular hairy 

 on the outside. Fruit a thickish ovoid capsule, dehiscing in 5 valves 

 at the apex. 



Common in the lowlands and on the river banks, where it is very 

 conspicuous. It is often found in small forms growing upon the 

 tiled roofs of houses along the gutters at Asuncion. It blossoms 

 from November to February, and even longer. 



Nicotiana longiflora, Cav., Descr. PL, 106. 



Asuncion (44). November-February. 



This tobacco is very common in the suburbs of Asuncion, and 

 frequently grows in the streets and waste grounds of the city itself. 

 The flow^er opens at night and closes early next day. Corolla with 

 a slender tube 7 or 8 cm. in length, white or bluish-white. Foliage 

 viscous-pubescent. The largest leaf which I noted was about 10 

 cm. long, and the largest described by DeCandoUe is 23 cm. long 

 by *l^ cm. wide. 



Nicotiana longiflora, Cav., var. grandifolia, Morong, n. var. 



This form is distinguished from the type by its magnitude, unequal calyx 

 lobes, and its denser pubescence. The stems are nearly twice as thick, tube 

 of the corolla 9 or 10 cm. long, lobes of calyx 15 to 20 mm. long, and the 

 largest leaves are 4-5 dm. in length by 1^-2 dm. in breadth. Flowers noc- 

 turnal, and slightly fragrant when freshly open and wet with the morning 

 dews. 



The large leaves often lie flat on the ground, and when hung in 

 the sun to dry cure like those of N. riistica. I have no doubt that 

 they contain nicotine enough to make a very good tobacco, as they 

 have all the taste of that while green.
