4 University of California Publications in Botany [Vol.5 



Since it is my intention to discuss this matter later and since, 

 at present, it is desirable only to enumerate and make reason- 

 ably plain what plants have been used in the work carried on 

 in the Botanical Garden of the University of California (U. C. 

 B. G.), I shall content myself with giving a list with descriptive 

 remarks of the types which have appealed to me as being 

 possibly fundamental or of other interest in experimentation. 

 In connection with each I shall use the number by which it 

 has been designated in the U. C. B. G. 



"Brazilian" 



11 

 TJ. C. B. G. 05. — The seed of this number was received 



under the name of "Choice Brazilian American" from the 

 United States Department of Agriculture in 1905. Its habit 

 and general characters are well shown in the photograph repro- 

 duced in plate 1. It is a tall plant, averaging about six feet 

 in height, producing laterals in succession above, but barely 

 being overtopped by them. The leaves are long, broad, and 

 decidedly cucullate at the tip. They are thin and silky in 

 texture, being minutely glandular-pubescent. The corolla is 

 pink, tubular below graduallv and moderatelv infundibuliform

equally so with those of 05. Altogether the plant is very near 

 to a plant grown in the U. C. B. G. from seed sent by Professor 

 Dr. 0. Comes, labelled as being of his Nicotiana Tahacum var. 

 hrasiliensis. It does not seem to answer exactly to his figure 

 of that variety (1899, VI) nor exactly to that of .V. Tahacum 

 var. havanensis {loc. cit. VII). In his later work (1905, p. 

 81, fig. 27) Comes figures a plant which he designates as 

 "Bahia" and which he considers as a combination of 

 his varieties hrasiliensis and havanensis which is close to our 

 plant, but not exactly of the same inflorescence at least. The 

 plant designated by Anastasia (1906, opp. p. 102) as A. Tah- 

 acum var. hrasiliensis is verv nearly the same as ours. It seems 



21 

 therefore, that we may designate the plants bred from 05 



U. C. B. G. seed as "Brazilian." Its exact characters and 



relation to other "Brazilian" combinations as well as "Havana" 



combinations will be considered when certain experiments involv-
