it in 1825 on the banks of a small branch of the "Multnomak 

 River," one of the southern tributaries of the Columbia River. 

 The plants cultivated today are, with little doubt, descended 

 from the plants grown from the seed collected by Douglas. No 

 plants of N. multivalvis are found wild at the present time, and 

 it is more than probable that even in the time of Douglas it 

 was not known except in Indian cultivation. It is still cul- 

 tivated and used ceremonially by certain Indian tribes. 



Nicotiana repanda Willd. 



Lehmann (1818, p. 40, pi. Ill) is responsible for the pub- 

 lication of this species which Willdenow apparently christened 

 as an herbarium specimen. The native country of the type 

 specimen is given as Cuba. The species grows in Mexico and 

 southwestern Texas, where seeds were obtained through the kind- 

 ness of Professor F. D. Heald of the University of Texas. The 

 plants are not easily grown but have been continued on under

U. C. B. G. 09. They agree with Lehmann's figure (loc. cit.) 

 as well as with that of Sims (1823, pi. 2484). They are well 

 represented by the photograph reproduced in plate 27. Our 

 plant is probably the N. repanda var. pandurata (Dunal.) 

 Comes (1899, p. 47). 



Nicotiana trigonophylla Dunal. 



In the southwestern United States and northern Mexico, in 

 the drier regions, there grows a species which varies quite a little, 

 which has been, and even still is, used by certain Indian tribes 

 for smoking. This is Nicotiana trigonophylla. It has been 

 grown, but with difficulty, in the U. C. B. G. for several seasons

under Nos. 07 and 09. The seed of the former was from San 

 Bernardino County and of the latter from Inyo County, both 

 of the State of California. In both cases it was from wild plants. 



In 1911 by planting in soil well underdrained and by using 

 cheese-cloth protection, the plants were grown successfully and 

 some of them with protection have even withstood the winter. 



The species is correctly placed in the Petunioides-section of
